8 Inch PU Roller Mecanum Wheel 800kg Total Load

This 8 inch mecanum wheel uses PU (polyurethane) rollers on a stainless steel core, mounted in a hard anodized 7075-T6 aluminum hub. The PU tread keeps grip high and running noise low while protecting epoxy and tile floors, and the bolt-on quick change roller module cuts maintenance downtime from hours to minutes.

Why this wheel fits outdoor AGV projects

• PU polyurethane rollers: 90A Shore tread offers abrasion resistance, high friction on dry concrete and low noise, with no marking on coated factory floors.
• 800kg total load: rated for an 800kg total platform load, about 200kg per wheel on a four wheel layout.
• Quick change roller module: each roller group is fixed by a single bolt-on module, so a worn roller is replaced on the vehicle without removing the wheel from the gearbox shaft.
• Sealed double row bearings: pre-greased and shielded to keep grit out of the bearing cavity and extend re-lubrication intervals on dusty floors.
• Hard anodized hub: 7075-T6 aluminum body with corrosion resistant anodized surface for humid working conditions.
• Stable omnidirectional motion: 9 PU rollers set at 45° give smooth lateral, diagonal and rotational travel with low vibration.

Mecanum motion principle

The mecanum wheel carries a series of rollers set at 45° to the wheel plane. By pairing left hand and right hand roller sets and driving each wheel independently, the chassis moves forward, sideways, diagonally or rotates in place without any steering mechanism. This gives AGV and AMR platforms full omnidirectional mobility in narrow aisles.

PU roller options

Standard rollers are PU. For special environments we also supply rubber rollers for higher grip, ESD conductive PU for electronics lines, and stainless steel rollers for high temperature or washdown areas. Roller hardness and color can be customized against your floor condition and duty cycle.

Typical applications

• Outdoor logistics and yard transfer AGV
• Industrial warehouse and production line AGV
• Mobile robot chassis requiring lateral docking accuracy
• Heavy duty transfer carts and automated handling platforms

Customization service

Diameter, width, shaft hole type (keyway or flange), roller material (PU, rubber, ESD conductive PU, stainless) and surface color can be customized. OEM and ODM orders are welcome, and drawing based development is supported by our in-house engineering team.

FAQ

Q: What material are the rollers?
A: Standard rollers are PU (polyurethane) with a stainless steel core, 90A Shore hardness. Rubber, ESD PU and stainless options are available on request.

Q: How long does a roller module replacement take?
A: One module is fixed by a single bolt set. On site replacement typically takes 5 to 10 minutes per wheel.

Q: What is the lead time?
A: 20-25 working days after deposit, covering both standard and customized shaft and roller configurations.
