Perfect Fit for 3D Printer
Exactly what I needed for my 3D printer upgrade. The 8mm inner diameter fit perfectly on the shaft.

Good Value for Money
Quality is good for the price. Shipping took a bit longer than expected but the product itself is solid.

High Speed Ready
Spins very fast without overheating. I use them in high RPM applications and they hold up well.

Smooth Operation for Drones
Used these for my drone motors and the difference is night and day. Very smooth spinning with minimal friction.
Q: Are these bearings made of stainless steel?
A: No, these are made of Chrome Steel GCr15 for optimal hardness and durability.
Q: Can I re-lubricate these bearings later?
A: Since these have ZZ metal shields, re-lubrication is difficult. We recommend replacing them when grease degrades.
Q: What is the maximum RPM for the 10mm size?
A: The maximum RPM varies by load, but they are rated for high-speed applications up to 30000 RPM under light load.
Q: What is the return policy if the size is wrong?
A: We offer a 30-day return policy for unused items in original packaging.
Q: Do you offer bulk discounts for over 50 packs?
A: Yes, please contact our sales team directly for bulk pricing options on large orders.
