High Temp Casters for Autoclaves, Ovens & Heat-Exposed Equipment

POSI Series — Heat-resistant wheels and casters with silicone rubber tread and synthetic wheel center, up to 482°F. Silicone rubber retains its elasticity and cushioning properties at elevated temperatures — a significant advantage over standard rubber compounds that harden or crack under sustained heat. The result is quieter, more floor-protective movement in hot environments. The POSI is a strong choice for autoclave carts, pharmaceutical trolleys, and any application where floor protection and smooth operation matter alongside heat resistance.

POH Series — Nylon heat-resistant wheels and casters, up to 338°F. Nylon is inherently resistant to a broad range of chemicals, making this series suitable for environments that combine moderate heat with regular cleaning agent exposure. The POH is the entry-level heat-resistant configuration for laboratory, food processing, and sterilization equipment that operates below 338°F.

POHI Series — Nylon heat-resistant wheels and casters, up to 482°F. The POHI extends the POH’s nylon performance to the same 482°F ceiling as the POSI, but with the harder-wearing, more chemically resistant properties of nylon rather than silicone rubber. For applications where chemical exposure is heavy and floor impact is less of a concern, the POHI typically offers better durability per dollar over time.
