Phenolic wheels also have a high resistance to impact damage while providing protection for floors in commercial and industrial settings. These easy rolling wheels are quieter than comparable steel wheels. Phenolic resin wheels feature a resistance to water, oil, and grease. Being non-metallic, these resin wheels are also spark proof.

Please Note: For 3/4″ axles, simply remove the spanner bushing (reduces 3/4″ to 1/2″). For axles requiring 5/8″ bore, spanner bushings and bearings in stock, also. Need a different style bearing? We have Delrin, Precision ball bearing, and tapered bearings available.
