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.
Temperature Range: -45ºF to +180ºF intermittent service (120º continuous service)
Hardness: 75(±5) Durometer Shore A scale
· Easy rolling and turning – for ergonomic advantage
· Quiet rolling, impact resistant, and very floor protective
· Absorbs shock to help protect equipment
· Maximum weather-ability and resistance to chemicals, water and steam
· USA-Made for fast lead times and the highest quality
· Rejects floor debris, such as metal shavings, for long service life
Not to mention the Colson Performa wheel is all MADE IN THE USA!!!
