8 rollers mecanum wheel made of polyurethane for 100 406mm industrial applications

These mecanum wheels feature eight independent polyurethane rollers and are available in two diameters – 100mm and 406mm. Designed for industrial automated guided vehicles (AGVs), mobile robots, and heavy-duty transfer carts, they enable omnidirectional movement including forward/backward, lateral strafing, and rotation without traditional steering mechanisms. The 100mm version is suited for compact logistics robots and small assembly platforms, while the 406mm model handles larger loads in factory automation and aerospace part transportation.

Each wheel uses high-grade polyurethane for the rollers, offering a shore hardness of 92A–95A. This material provides excellent abrasion resistance, chip resistance, and floor protection compared to nylon or steel rollers. The eight-roller geometry ensures continuous contact with the ground, minimising vibration and maintaining traction even on slightly uneven surfaces. Precision bearings inside each roller reduce rolling resistance and allow smooth motion at speeds up to 2.5 m/s, depending on loading and floor conditions.

In real‑world industrial applications, these mecanum wheels reduce floor space requirements by allowing equipment to turn in place and move diagonally. Warehouses moving heavy pallets, automotive final assembly lines, and mobile lifting platforms benefit from reduced cycle times because operators no longer need three‑point turns or wide aisles. The polyurethane rollers also absorb shock loads and produce less noise (typically below 75 dB at full load) than metal alternatives, creating a safer working environment.

Longevity is a key concern for production managers. The polyurethane compound resists swelling from oils, greases, and mild chemicals commonly found in machine shops and packaging areas. For demanding outdoor or wet environments, the 406mm model can be fitted with additional sealing on the roller bearings. Regular maintenance is limited to removing debris from between rollers; no central lubrication points are needed, as each bearing is factory lubricated for the wheel’s service life (typically 10,000 operating hours under rated load).

For buyers seeking reliable motion components, Industrial Rubber Wheels from ZHXPRECI | China OEM/ODM Factory Supplier Custom Elastomer Wheels & Rollers offers full customisation of these mecanum wheels. You can specify different polyurethane hardness values (70A to 98A), alternative elastomers such as nitrile rubber or Hytrel, modified roller geometry for special floor types, and custom bores or keyways. Prototype quantities are supported, and production lead times for OEM orders start from 15 working days. All wheels are tested for roller concentricity (≤0.3 mm runout for 100mm, ≤0.5 mm for 406mm) before shipping.

Integration with existing control systems is straightforward because the kinematic behaviour of these eight‑roller mecanum wheels follows standard omnidirectional models. Speed and angle commands can be directly used in ROS, PLC‑based motor controllers, or any four‑wheel independent drive system. The consistent roller profile and uniform polyurethane hardness ensure predictable vector summing, making tuning easier for motion control engineers. Whether upgrading an existing AGV or designing a new heavy‑payload platform, these polyurethane mecanum wheels provide a field‑proven solution that balances durability, silent operation, and true omnidirectional freedom.
