4" x 2" RUBBER ON NYLON WHEEL SWIVEL CASTER WITH 3/4" THREADED STEM - Part #: 7RTP042RIR

Specifications: 

Rubber on nylon wheels offer a smooth, quiet, & cushioned ride that will protect floors for an economical price. The nylon core provides equivalent load and impact capacities to cast iron, but is rust free and can be used for applications requiring wash downs, high humidity, and outdoor environments. The down side to rubber wheels is they can leave marks on the floor and do not hold high capacities. If you need a non-marking wheel or more capacity, we recommend our thermoplastic rubber wheels or polyurethane wheels.

We would not recommend these wheels for applications that require sitting in one spot for long periods of time under heavy loads.
