The 3" Rigid/Swivel/with Brake Double Bearings TPR Caster Wheel is a medium-duty mobility solution tailored for industrial and commercial scenarios. It integrates three functional modes—rigid for fixed-direction movement, swivel for flexible steering, and brake-equipped for stable positioning—to adapt to diverse workflow needs. Engineered with double bearings and TPR (Thermoplastic Rubber) tread, this caster wheel delivers smooth, long-lasting performance across multiple surfaces, from polished wood floors in offices to concrete floors in warehouses. Whether mounted on production line carts, medical trolleys, or material handling equipment, it protects both transported goods (via shock absorption) and flooring (via non-marking tread), making it a versatile choice for sectors like manufacturing, healthcare, and food processing.
TPR Tread: Features a 80-85 Shore A hardness TPR tread, which offers exceptional shock absorption to reduce vibrations during movement—critical for protecting fragile items like electronic components or medical devices. The tread is also non-marking, ensuring no scratches on sensitive floors such as tile, vinyl, or hardwood.
PP Wheel Core: The wheel core is constructed from PP (Polypropylene), a lightweight yet durable material that resists acids, alkalis, and moisture. This meets hygiene standards for food processing facilities and laboratories, where cleanliness is non-negotiable.
Double Bearings: Equipped with double bearings, the caster minimizes friction during rotation, ensuring smooth rolling even under repeated use. This design also extends the wheel’s service life, reducing replacement frequency for businesses.
Integrated Brake System: The built-in brake locks both the wheel’s rotation and swivel function, preventing unintended movement when loading/unloading heavy items or during stationary use—enhancing workplace safety.
Key Dimensions: For the 3" (75mm diameter) model (e.g., 301ZN-01-752-332-2G), it has a 32mm tread width, 105mm load height, and a 96*66mm mounting plate (with a secondary 75*45mm plate) featuring 8.5mm holes for easy installation. Its maximum load capacity reaches 90kg, fitting most medium-duty transport needs.
Superior Shock Absorption: TPR’s elastic properties absorb jolts during movement, safeguarding delicate goods like laboratory reagents or hospital supplies from damage.
Floor-Friendly Performance: The non-marking TPR tread eliminates the need for additional floor protectors, saving businesses time and cost on floor maintenance.
Temperature Resistance: Maintains flexibility in cold environments (e.g., refrigerated warehouses at -10°C) and resists deformation in high-temperature settings (e.g., manufacturing workshops up to 60°C), ensuring consistent performance year-round.
Quiet Operation: The soft TPR tread reduces noise during rolling, creating a peaceful environment—essential for libraries, hospitals, or office-based storage areas where noise disruption is unacceptable.
Multi-Surface Traction: Delivers strong grip on uneven or slippery surfaces, such as oily workshop floors or wet retail spaces, preventing carts from tipping and improving maneuverability.

A1: It offers broad multi-surface compatibility, including wood, tile, vinyl, concrete, and slightly uneven floors. The TPR tread’s texture ensures stable movement without slipping, even on semi-smooth surfaces like polished stone.
A2: The 3" (75mm) model supports up to 90kg. For heavier loads, larger options are available: 4" (100mm) models handle 100kg, and 5" (125mm) models support 125kg—ideal for industrial equipment requiring higher weight capacity.
A3: No. The brake is designed for low maintenance: its components are corrosion-resistant, and regular wiping (to remove dust or debris) is sufficient to keep it functional. No lubrication or part replacements are needed under normal use.
