High Temperature Polypropylene Castors Brown 3 Inch Casters With Brake

75mm 280 Degree Celsius High Temperature PP Caster Wheel With Brake For Machine

Feature

This caster is a specialized component engineered for extreme thermal environments. Its core features focus on maintaining structural integrity and functionality at 280°C.

• 75mm Diameter: A compact size suitable for machinery with limited ground clearance, while still providing stable mobility.

• 280°C High-Temperature Resistance: This is the defining feature. The wheel is manufactured from a specialized material capable of withstanding continuous exposure to 280°C. Note: Standard Polypropylene (PP) cannot withstand this temperature. Therefore, this caster likely uses a high-performance engineering plastic (such as PEEK or Polyimide) or a specialized composite material.

• High-Temperature PP (or Equivalent) Wheel: The wheel material is specifically formulated to resist deformation, softening, and degradation at extreme temperatures. It maintains its load-bearing capacity and rolling characteristics even when exposed to ovens, kilns, or hot machinery.

• Integrated Brake System: The caster includes a braking mechanism designed to lock the wheel in place. Crucially, all components of the brake system (lever, cam, brake pad) are also constructed from or treated with high-temperature resistant materials to ensure reliable function in extreme heat.

• High-Temperature Bearing System: The wheel hub contains bearings (often precision ball bearings) that utilize high-temperature lubricants (such as PFPE grease) or solid lubrication, and may feature special steel or ceramic balls to prevent seizing or failure at 280°C.

Functions

In extreme heat environments, this caster performs critical functions to ensure safe and efficient operations:

• Safe Mobility in High Heat: Enables the movement of machinery, racks, or containers that are themselves hot or operating within a hot environment (like an oven or kiln). It allows operators to position equipment without waiting for it to cool down, improving workflow efficiency.

• Reliable Braking Under Thermal Stress: Provides secure stopping and parking capability even when the caster is exposed to 280°C. This prevents equipment from rolling unintentionally during loading/unloading in high-temperature zones, which is critical for safety.

• Structural Stability at Temperature: Maintains its dimensional integrity and load capacity despite continuous thermal expansion and exposure. It resists warping, cracking, or softening, ensuring the equipment remains level and mobile.

• Resistance to Thermal Degradation: Withstands the embrittlement and chemical breakdown that would destroy standard casters, providing a long service life in applications where ordinary wheels would fail quickly.

Ideal Applications

This caster is essential for any industry involving heat treatment, baking, or processing at elevated temperatures.

• Heat Treatment and Metalworking: For moving racks, baskets, or carts carrying metal parts through furnaces, tempering ovens, or quenching lines.

• Commercial and Industrial Baking: For bakery racks and trolleys that are pushed directly into proofers or large industrial ovens where ambient temperatures are extremely high.

• Glass and Ceramics Manufacturing: For transporting molds, freshly formed glass items, or ceramic ware through annealing lehrs or drying ovens.

• Automotive and Aerospace Manufacturing: For moving components through paint curing ovens or composite material curing autoclaves.

• Laboratory and Research Equipment: For mobile racks and stands used inside environmental chambers, high-temperature test ovens, or sterility tunnels.
