Ultra High Capacity Polymer
Caster Wheels
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.

Hub Length and Bearing ID are measured with Top Hat Spanners.
You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these wheels are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
