Phenolic wheels 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.
Quality casters featuring bright zinc plating, 1/2" diameter axle bolt and grease fittings. Machined forged steel dual ball bearing raceway absorbs load and thrust in a radial direction, which provides superior shock loading capabilities. This unique design eliminates problems associated with kingpin failure due to severe shock loading. 4 Position notches to accept 4-position locks (locks sold separately). Ideal for industrial and commercial equipment, platform trucks, shop floors, warehouse carts and freight terminals.
