Basic Information

• Available Sizes: 4″, 5″, 6″, 8″

• Load Capacity: 250-400KG

• Our Heavy-Duty Grey TPR (Thermoplastic Rubber) Stainless Steel Casters offer the perfect combination of floor protection, noise reduction, and sterile durability. Featuring a synthetic rubber tread chemically bonded to a heavy-duty polypropylene core, these casters are housed in premium rust-proof Grade 304/316 stainless steel brackets. Supporting reliable weight capacities of up to 400 kg per caster, they are equipped with double-ball swivel raceways and sealed precision bearings to deliver effortless steering and maintenance-free longevity in wet or sterile environments.

Key Features

1. Ergonomic Shock Absorption: The soft durometer of the TPR tread acts as a cushion for your equipment. It absorbs surface shocks and impacts, making it exceptionally easy for staff to push carts over tile grout lines, elevator thresholds, and uneven thresholds without rattling delicate cargo.

2. Chemical & Moisture Resistance: TPR is highly resistant to water, mild acids, alkalis, detergents, and alcohol-based chemicals, ensuring exceptional durability in laboratories, food processing plants, and medical environments where frequent washdowns and sanitization are required.

3. Excellent Washdown & Chemical Resistance: Designed to thrive in strict hygiene regimes. The combination of synthetic TPR and an all-stainless steel frame withstands repeated washdowns, high humidity, steam cleaning, and exposure to common institutional disinfectants and alcohols without degrading.

4. Interference-Free Precision Swivel: Engineered with tight tolerances and premium stainless steel bearings that prevent wobbling, ensuring the caster follows the operator’s intent instantly and tracks perfectly straight when needed, reducing workplace physical strain.
