FAQs

Do you ship your products Worldwide?

Yes. We ship worldwide and process most orders within 24 hours for fast and secure delivery.

What is included when I order the PU 45A high traction wheel?

You can choose between the tire only (pair) option or the full set (pair) with CNC aluminum hubs. Both options are lightweight, strong, and designed for robotics, RC, and automation projects.

Are polyurethane 45A wheels durable for continuous use?

Yes, PU 45A wheels are highly durable and wear-resistant. They are designed for long-term projects where consistent traction and strength are more important than maximum grip.

What shaft size does the PU 45A wheel support?

The wheel has a 6 mm bore size, which fits most standard DC and brushless motor shafts used in robotics and RC vehicles. It also includes an M4 set screw and Allen key for a secure mount.

How is the PU 45A traction wheel different from the PU 30A wheel?

The PU 45A wheel has a medium hardness rating, which means it offers slightly less grip than the 30A but much higher durability. It is ideal for robotics and automation projects that need long-lasting wheels with consistent performance.

Can these wheels be used for RC cars and robotics projects?

Yes, these wheels are designed for robotics, RC cars, automation systems, and custom engineering projects. The strong grip and CNC aluminum hub make them ideal for both competitive robots and high-performance RC vehicles.
