Features and Benefits of Super Erecta Stem Casters
- Polyurethane is a synthetic rubber with significant resistance to temperature, shock, fuels, oxidation, detergent and oils. This material offers a long life, with the wear resistance of hard rubber and the resilience of soft rubber, and high floor protection for use in a cleanroom environment.
- High Modulus Cleanroom-Approved casters provide vibration dampening in controlled environments. Each caster includes a nickel horn, resilient tread wheel, dust cover and Celcon bearing. These casters also resist virtually all cleaners, solvents, oils and acids. Not recommended for wet or humid environments.
- High Modulus Cart-Washable Cleanroom-Approved casters can be washed with the power washers commonly used to clean carts. These casters are grease sealed with zerk fittings in the swivel and axle.
A Note on Load Ratings
"Rated Capacity" is, by definition, the maximum load per caster recommended by the manufacturer for use over smooth floors at operating speeds of 3 mph or less. As a general rule, the true load-bearing capacity of a four-caster cart is rarely more than three times the rated capacity of a single caster. Unbalanced loads, acceleration forces, cornering, uneven floors, and other obstacles place too great a demand on each wheel to permit extensive operation at full rated capacity.
