Choose the Correct Heavy Duty Wheels for Your Industrial Caster and Wheel Applications

Choose the Correct Heavy Duty Wheels for your Industrial Caster and Wheel Applications


We have talked about how heavy duty casters can provide an amazing benefit in your heavy material handling transporting and moving equipment.  I consider heavy duty wheels to be 1,200# capacity to about 40,000# capacity.  However if you do not have the correct wheels for moving these heavy items you will have nothing but problems.  Some of the issues you may encounter when using an under rated capacity wheel include:  wheel breaking or flattening, bearings busting out of the wheel, using incorrect wheel material which can damage the floor.  All of these scenarios can cause a catastrophic failure of the casters and cart that you are moving the equipment on resulting in possible damage and injury to operators…. Not to mention the job will not get done.  Therefore, let’s see what factors we need to consider when choosing the correct heavy duty wheel for moving heavy equipment.  At www.heavy-dutycaster.com we list the size of the wheels and wheel options, and capacity to help you choose the best wheel for your heavy duty caster application.   
(1)  Know the weight you will be pushing, pulling, towing, or moving.
(2)  Know the type of floor and the condition of the floor you are rolling the wheels.
(3)  Are you manually pushing or pulling the cart?  Or are you using a tugger or towing the cart?
(4) Do you have harsh environments the wheels will be exposed to?
(5) How tall can you go?  What size diameter and width wheel can you use?
We offer over 40 different styles of heavy-duty wheels. Our wheels come in many different diameters, tread widths, colors, and capacities. Specific wheels provide floor protection, high heat applications, wash down, chemical resistance, and more. Our wheels come with a variety of bearings such as: roller bearings, tapered roller bearings, precision ball bearings, stainless steel bearings, delrin and bronze bearings, and oilex bearings. Specific wheels feature flat tread, crowned tread, donut tread with different durometers and hardness. Wheels available: phenolic wheels, high temp wheels, hard and soft rubber wheels, thermoplastic rubber wheels, polyurethane wheels, elastomer wheels, cast iron steel wheels, ductile steel wheels, drop forged steel wheels, semi-pneumatic wheels, rubber on cast iron and poly on cast iron wheels, poly on aluminum wheels, v-groove wheels and others.           

Wheel selection and wheel bearings are another very important factor when selecting heavy duty casters.  The larger the wheel the easier it will be to get started rolling and keep rolling, especially over rough terrain or uneven floors and thresh holds.  Heavy duty casters usually start with a 6” diameter wheel however even a 3” diameter wheel can be used in heavy duty casters when a low profile is needed.  6” x 3” up to 16” – 4” wide wheels are commonly used.  Different types of wheel material is also very important.  Steel wheels and ductile steel and forged steel wheels give you the most carrying capacity but can be rough on floors.  Heavy duty polyurethane on cast iron wheels can give wonderful floor protection and still yield a great capacity.  High impact polymer wheels and Ergolastomer wheels work great in many applications.  We can use standard straight roller bearings in these wheels but the best wheel bearings for heavy duty applications are precision sealed ball bearings, and tapered roller bearings.  The precision ball bearings and tapered roller bearings allow for an easier start and better roll with less force and also will withstand towing.  The larger the wheel the heavier the axle as well.

4 Key Factors to Consider When Using a Heavy Duty Caster for Your Material Handling Application.

4 Key Factors to Consider When Using a Heavy Duty Caster for Your Material Handling Application.

Heavy duty casters can provide an amazing benefit in your heavy material handling transporting and moving equipment.  I consider heavy duty casters to be 1,500# capacity to about 40,000# capacity.  However if you do not have the correct caster for moving these heavy items you will have nothing but problems.  Some of the issues you may encounter when using an under rated capacity caster include:  wheel breaking or flattening, bearings busting out of the wheel, caster forks bending and bowing, top plate bending, damaging the floor.  All of these scenarios can cause a catastrophic failure of the casters and cart that you are moving the equipment on resulting in possible damage and injury to operators…. Not to mention the job will not get done.  Therefore, let’s see what factors we need to consider to choose the correct heavy duty caster for moving heavy equipment.  At www.heavy-dutycaster.com we list the size of the casters, top plate size, wheel options, and capacity to help you choose the best caster for your heavy duty application.

                      
 (1)  Know the weight of the cart or the items you are installing the heavy duty casters.  Also consider if the weight being transported will be a centralized load or an offset load.  It is very important for most of the weight to be evenly distributed over 3 or 4 casters depending on how many casters you use and the pattern of the casters.  It is a very safe formula to divide the weight you are going to be moving by a factor of 3.  Typically most equipment uses 4 casters in a square or rectangular pattern… If this is the case then divide by 3 and you will get a safe weight capacity per caster needed.  So if your cart and equipment weighs 6,000 lbs.  Then divide 6,000 / 3= 2,000# capacity per caster.  This way you will definitely have enough capacity over 4 casters.  If you have a great floor with no cracks or obstructions and the weight will always be evenly distributed over the 4 casters then you can divide by 4 and be ok.  Caster patterns can be diamond style, rectangular, square, tri-style, rigid in the center and 2 swivel on each end, etc.

(2)  Kingpinless swivel caster versus a swivel caster with a kingpin.  The kingpin in a swivel caster is the bolt that goes through the center of the swivel raceway and is held together with a bradded nut and threaded bolt.  The raceway has ball bearings that go around the king pin in a swivel race and allows the swivel action to flow free.  This is the most common way a swivel caster is manufactured and typically provides great swivel action up to about 1,500#.  When selecting a heavy duty caster with more than 1,500# we typically go to a kingpinless swivel caster.  This means the caster does not have a kingpin.  Instead it has a precision machined and hardened sealed swivel raceway that is larger diameter.  Inside the sealed race is 3/8” or larger ball bearings that withstand heavier shock load and towing.  This gives the swivel action a more robust swivel lead and stronger more durable swivel action when under a heavy load.

 
(3)  Top Plate Size and fork thickness is another factor in selecting the heavy duty casters.  We have top plate sizes ranging from 4” x 4.5” x ¼” thick, 4.5” x 6.25” x ¼” thick, 5.25” x 7.25” x 3/8” thick, 6.25” x 7.5” x 5/16” thick, 8.5” x 8.5” x ½” thick among other sizes.  The heavier the load then the larger the top plate and thicker the top plate and fork thickness will be.  Make sure you choose the correct top plate and bolt hole spacing for your equipment if you are bolting the casters to the cart or dolly.


(4)  Wheel selection and wheel bearings are another very important factor when selecting heavy duty casters.  The larger the wheel the easier it will be to get started rolling and keep rolling, especially over rough terrain or uneven floors and thresh holds.  Heavy duty casters usually start with a 6” diameter wheel however even a 3” diameter wheel can be used in heavy duty casters when a low profile is needed.  6” x 3” up to 16” – 4” wide wheels are commonly used.  Different types of wheel material is also very important.  Steel wheels and ductile steel and forged steel wheels give you the most carrying capacity but can be rough on floors.  Heavy duty polyurethane on cast iron wheels can give wonderful floor protection and still yield a great capacity.  High impact polymer wheels and Ergolastomer wheels work great in many applications.  We can use standard straight roller bearings in these wheels but the best wheel bearings for heavy duty applications are precision sealed ball bearings, and tapered roller bearings.  The precision ball bearings and tapered roller bearings allow for an easier start and better roll with less force and also will withstand towing.  The larger the wheel the heavier the axle as well.

5 Key Features of Stainless Steel Swivel Casters for Wash Down Applications

Blog:  5 Key Features of Stainless Steel Swivel Casters for Wash Down Applications
Many applications require a stainless steel swivel and rigid caster for wash down industrial applications.  Typically this happens in food processing facilities, pharmaceutical production, marine equipment, bakeries, and other clean or corrosive environments.  Different cleaners, steam, water, and even salt water can destroy mild steel casters and certain types of wheel material in a matter of months.  So we employ 5 key features on the stainless steel casters to keep your operation running and might I say……. Rolling!
(1)  Use a high quality #304 stainless steel swivel and rigid rig that is machined and polished if possible.  A typical medium to heavy duty stainless steel caster will have a double ball raceway with a 5/8” kingpin.  The plate is typically a 4” x 4.5” top plate with slotted 3” x 3” bolt hole spacing and ¼” thick.  All the ball bearings in the swivel race to be stainless steel also to disallow corrosion in the swivel race.










(2)  Have raceway seals installed on the upper and lower swivel raceways.  The rubber raceway seals help keep debris from lodging into the raceway bearings and creating drag when swiveling.  Also when washing with a high power sprayer they can help prevent direct blasting of the water or detergent from spraying directly into the race.  The seals also help keep food grade grease or high temp grease packed into the bearings and not as likely to be washed out.

(3)  Grease fittings should always be in the swivel race.  This allows maintenance to provide preventative maintenance on the casters and keep them properly lubed from the wash down sprays and detergents or salty environment.

(4)  Wheel selection is probably the second most important feature to address.  When selecting a wheel for a stainless steel caster application you need to take into account the wash down protocol.  Will detergent be used?  Will there be grease, oils, chemicals, cleaners, salt, brine, blood or steam?  All of this is good information to know before selecting the wheel.  Wheels can range in a wide price range.  For some applications a phenolic wheel with stainless steel roller bearings will work for around $70.00 but in other applications you will need a much more durable wheel that will withstand more chemicals and cleaners.  In this case a solid elastomer polyurethane wheel with stainless steel precision ball bearings will be better and they run about $120.00 per swivel caster.  Also always make sure you have a stainless steel or delrin or bronze bearing in these wheels.  Delrin is a solid plastic bearing that withstands just about every chemical and wash down application.  The provide good rollability but not the best.  Stainless steel roller bearings make for a good ergonomic roll but after time can give out due to long use.  Stainless steel precision ball bearings are a great option because they are sealed and do not let debris or chemical or water into the actual bearings.  These can provide long lasting use and are very ergonomic to push.









(5)  Accessories for the stainless steel casters are important also.  If you want a brake for the wheel then the brake mechanism also needs to be stainless steel so it too will withstand the wash down environment.  Same goes for swivel locks or other accessories.

Can Spring Loaded Casters Solve Your Sensitive Material Handling Problem?

Spring loaded casters are actually only helpful in a few applications in the industrial and commercial material handling world.  Spring loaded casters have three specific advantages.  One is they are designed to reduce vibration while rolling or maneuvering product on a cart.  The second is to help prevent shock loads when placing product or pallets on a carts or platform truck.  Third is noise reduction while transporting on a cart or buggy or truck.
Many times there may be sensitive material such as electronic components, glass, medical supplies and equipment and other material that needs little vibration while being transported.  Preventing shock locks is another unique feature of the spring loaded caster.  Typically the casters begin to engage the spring at about 400 – 700 pounds depending on the type of wheel used.  Also these casters can help eliminate excessive noise while transporting across rough floors or transitions.  The wheel chosen in this application is also important as we can use many types of rubber or urethane wheels to help with noise, shock load, and vibration.
Our spring loaded caster wheels have a standard 4.5” x 6.25” top plate to give the swivel race a larger footprint to help distribute the live load.  The springs are encapsulated in a polyurethane block under the swivel raceway.  There is about ¼” compression travel for the springs.

 

The spring loaded casters are only available in the swivel action caster.  The rigid if needed in an application do not have a spring actuation.

Electrically Conductive and Anti-Static Caster Wheels Can Be an Important Solution for Many Industrial and Commercial Caster Applications

Electrostatic discharge (ESD) can be created by swivel and rigid caster wheels when they are rolled across the floor. In some applications the buildup of electricity can be harmful to the products being transported on the cart.  The operator can also be shocked when touching the steel or plastic cart.  If you are in the medical instrumentation market, electrical or semi-conductor production market, automotive industry, hospitals, pharmaceuticals, or chemical industries then you may need anti-static caster wheels.  Not to mention flammable or highly explosive environments then it is best to have a wheel that dissipates an electric charge.
Most of the conductive wheels that we use for these applications are made of a thermoplastic rubber compound on poly core.  The wheels in the picture are a grey Performa wheel with precision ball bearings and are non marking.  They have a capacity of 410 lbs. and are 6” diameter x 2” wide tread width.  These are available in 3” up to 8” in varying capacities.

Performa Conductive wheels have been rigorously tested and approved by an independent lab and meet the requirements of federal specification FF-C-88C. This specification requires an average electrical resistance of less than 250,000 ohms. For other wheel sizes, please consult factory for availability.
