Industrial Castor Wheel Materials: Rubber, TPR, PP, PU and Nylon

Elastic and Solid Rubber

Elastic rubber is often considered where quieter travel, resilience and vibration absorption matter. Solid rubber is a durable general-purpose option. Hardness, wheel center and bearing still affect starting force, heat and rated load.

Thermoplastic Rubber

TPR wheels can support quiet indoor travel and floor protection, making them common in institutional and lighter equipment groups. Verify load, temperature, speed and chemical exposure because not every TPR formulation has the same limits.

Polypropylene

Polypropylene wheels are hard, lightweight and can provide low rolling resistance. Floor noise, impact and the specific chemical environment must be considered. The harder tread can transmit more vibration to equipment and loads.

Polyurethane

Polyurethane wheels are widely used to balance load, wear and rolling performance. Tread formulation, hardness, bond, hub and temperature influence suitability. Confirm whether the floor contains metal debris, oil, moisture or joints that can damage the tread.

Nylon or Polyamide

Nylon wheels can carry higher loads with low rolling resistance on smooth floors. They are harder and can transmit more noise or shock than resilient wheels. Water absorption, temperature and chemical exposure should be checked for the exact grade and operating environment.

Include Hub and Bearing Construction

Plain bore, roller, single-ball and two-ball bearing versions can have different hub lengths, bore sizes, rolling effort and maintenance needs. A tread material comparison is incomplete without the center, axle and bearing configuration.

Compare Diameter, Width and Load

Larger diameters generally cross floor joints more easily, while wheel width influences contact pressure and turning effort. Use the exact product code table to compare these dimensions with rated load and overall castor height.

Test the Real Floor

For sensitive floors or continuous travel, trial a representative wheel at the intended load and speed. Check starting force, noise, marking, tread heat and damage after passing normal obstacles.

Compare the Product, Not Only the Material

Send application, floor, speed, temperature, chemicals, wheel diameter, mounting and quantity when requesting a recommendation. Record the approved model code so replacement parts match the tested construction.
