Product Overview
When racks roll in and out of ovens all day, ordinary polyurethane and rubber wheels soften, flat-spot and fail — phenolic wheels exist for exactly this duty. The material, a macerated-fabric phenolic composite, is dimensionally stable and load-capable at temperatures where polymers give up, with commercial ratings commonly quoted around 220–260°C depending on construction; buyers should confirm whether the quoted rating covers continuous or intermittent exposure, since sustained heat degrades both wheel and grease. Two honest caveats belong in any specification: phenolic treads are hard and noisy and will mark or wear resinous and painted floors, and bearing grease must be rated for the actual temperature (standard grease liquefies and drains out above roughly 150°C). Manufacturers listed here supply phenolic wheel casters with plated or stainless rigs, swivel locks that keep bakery racks tracking straight, and guidance on bearing and grease selection per oven cycle profile.
