Genuine C&U Product

Verified the branding on the shields. These are authentic C&U bearings. Packaging was secure with anti-rust paper.

Good Industrial Quality

Using these in a small conveyor motor. They fit perfectly and run quietly. One bearing felt slightly stiffer than the others but still acceptable.

Smooth Operation

Installed in my 3D printer fan motor. Very quiet operation. Shipping took a bit longer than expected but product is good.

Perfect for Skateboard Rebuild

Bought the 608 RS bearings for my longboard. They spin smoothly and seem very durable. Great value for the price compared to local shops.

5 FAQ

Q: Are these bearings pre-lubricated?

A: Yes, all C&U bearings come pre-lubricated with standard grease suitable for general operating temperatures.

Q: Which bearing size is standard for skateboard wheels?

A: The 608 series (specifically 608-2RS or 608-ZZ) is the standard size for most skateboard wheels.

Q: Can these handle high RPM applications?

A: These are standard precision P0 bearings. They handle typical motor and wheel speeds well but are not designed for extreme high-speed spindles.

Q: What is the difference between Rubber and Metal seals?

A: Rubber seals (2RS) offer better protection against dust and water. Metal seals (ZZ) have less friction and are suitable for cleaner environments.

Q: Do you offer bulk pricing for over 100 units?

A: Yes, please contact our sales team through the store page for volume discount inquiries on bulk orders.
