These wheels provide high load capacity without causing floor wear associated with metal wheels. Unlike polyurethane wheels, there is no risk of flat spots or delamination if these wheels are left parked for a prolonged period. Instead of injection molding, these wheels are compression molded and then machined. Their straight sided shape maximizes load capacity.
Non Marking Black Polymer Wheels. Compression Molded, then machined Straight sides to maximize load capacity. 4 Precision Sealed Ball Bearings in wheels that are 3″ and 4″ wide. Tread Face: FLAT No Flat Spots, No Delamination! Resists corrosion and most chemicals Hardness ( Durameter ): 80 shore D Temperature Range: -20° F to 250° F Approximate Melting Point: 500 degrees Fahrenheit.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
