100mm-406mm Mecanum Wheel Polyurethane Heavy Duty Industrial 8 Rollers Omnidirectional Wheel

Precision omnidirectional drive for demanding industrial logistics
This series of heavy duty Mecanum wheels combines polyurethane tread, an eight-roller design, and diameters from 100mm up to 406mm. Each wheel delivers true omnidirectional movement — forward, backward, lateral, and rotational — without traditional steering mechanisms. Built for continuous operation in automated guided vehicles (AGVs), mobile robot platforms, and factory material handling systems, these wheels reduce floor wear, lower noise, and offer outstanding load capacity across the full size range.

Engineered for harsh environments and high cycle life
The polyurethane tread is cast directly onto a precision roller core, providing high tear resistance, excellent chemical stability against oils and greases, and a shore hardness around 95A. The eight individually sprung rollers absorb uneven floor surfaces while maintaining smooth motion. Heavy duty steel or billet aluminium hubs are standard, with sealed ball bearings that require no regular maintenance. Every wheel is dynamically balanced before shipment, ensuring vibration‑free operation at speeds up to 2.5 m/s.

Application-focused dimensions & performance
Smaller wheels (100–200 mm) are ideal for compact AMRs, hospital logistics robots, and light industrial carts where space is limited. Mid‑range sizes (254–306 mm) serve heavy duty AGVs in warehouse pallet movement and assembly line shuttles. Large diameters (356–406 mm) handle off‑road dollies, heavy machinery movers, and port container transporters. All versions maintain precise kinematic control — each wheel’s roller angle is 45°, allowing true holonomic motion even with uneven load distribution.

Why choose this heavy duty omnidirectional wheel

Lower total cost of ownership – polyurethane lasts 3x longer than rubber under abrasive factory floors.
Minimised floor marking – non‑marking compound protects epoxy and painted surfaces.
Plug‑and‑play integration – standard shaft diameters and keyways match most DC servo and stepper motors.
Field‑replaceable rollers – each roller can be swapped in minutes without dismantling the whole wheel.

Reliability for 24/7 industrial automation
Every wheel undergoes a full radial and axial runout test, plus a 30‑minute loaded dyno run to verify roller articulation. The design avoids glued or pressed‑in rollers that can fail under shock loads; instead, each roller sits on an independent hardened steel shaft with retaining rings. For outdoor or wet environments, an optional stainless steel hub and sealed roller bearings are available. Custom diameters between 100mm and 406mm can be manufactured in low MOQs, with lead times of 15–20 working days.

Compliance and safety
These wheels meet ISO 9001:2015 manufacturing standards and comply with ANSI/ITSDF B56.5 for AGV components. Each unit is marked with a unique serial number for traceability. For safety‑critical applications, dynamic load testing certificates are supplied with every batch.
