Frequently Asked Questions
What is this wheel used for?
This heavy-duty omni wheel is ideal for mobile robots, AGVs, AMRs, robot bases, smart wheelchairs, and other automated mobility applications that require precise 360-degree multi-directional movement.
Can it fit my motor or chassis?
Please confirm the wheel diameter, bore size, and mounting pattern before ordering to ensure a proper fit. If you need assistance matching the wheels to your specific motor shaft or chassis, feel free to contact our technical support.
What surfaces is it best for?
It is best optimized for flat indoor surfaces such as smooth concrete, epoxy floors, and tile. Featuring premium TPU (Thermoplastic Polyurethane) rollers, the wheels offer excellent anti-slip traction and wear resistance while ensuring low noise and floor protection under heavy loads.
Do you offer drawings or CAD files?
Yes, CAD or STEP files are available for select models upon request. Engineering teams can contact us directly to obtain 3D models for chassis integration and simulation.
Do you support custom mounting or OEM solutions?
Yes, we provide full OEM/ODM solutions. We can customize dimensions, bore specifications, shaft adaptations, and load capacities tailored to your industrial automation projects.
Can I buy a sample or single unit?
Yes, sample or single-unit orders are available depending on the active listing and current stock level. This allows you to test and verify the performance on your prototype before committing to volume wholesale orders.
