5 Inch High Temp Phenolic Wheel Swivel 10mm Threaded Stem Caster SCC The Service Caster Series #20 is ideal for bakery racks, light and medium duty material handling, carts, equipment, and shop projects. The zinc plated finish provides durability under any condition, and the high temp phenolic wheels- quieter than comparable steel wheels- have a high resistance to impact damage, providing protection for floors in commercial and industrial settings. This caster is ideal for use in high temperatures associated with baking, performing consistently in temperature ratings of 475°F continuous usage to 525°F intermittent usage. Not only are they resistant to water, oil, and grease, but because they are non-metallic, these wheels are spark proof, keeping you safely moving forward.
