Heat Resistant
Phenolic and hi-temp nylon wheels rated to 230°C and 320°C. For ovens, autoclaves, and hot-process environments.
Standard PU and nylon castors soften and deform above 80°C — a critical failure point for any equipment entering ovens, autoclaves, sterilisers, or high-temperature curing lines. CastorTrade's heat resistant range uses hi-temp nylon wheels (rated to 230°C) and phenolic resin wheels (rated to 320°C) to keep carts rolling safely through thermal process cycles.
Phenolic wheels are the industry standard for bakery oven trolleys, powder-coating oven racks, and food processing equipment. Phenolic's 320°C rating also suits more demanding cycles found in aerospace composite curing, rubber vulcanisation, and industrial autoclave operations. Both materials maintain dimensional stability under sustained heat and resist the thermal shock of rapid oven entry and exit.
All heat resistant castors use high-temperature grease-packed precision bearings rated to match the wheel's thermal specification. Brackets are zinc-plated steel across the range. If your application involves steam, chemical exposure, or temperatures above 320°C, contact us for custom specification guidance.
