High quality industrial parts

Used these for a small conveyor project. They handle the speed well and seem very durable. Will buy again.

Perfect for my 3D printer

These bearings fit perfectly on the shafts. Very smooth rotation and minimal noise. Great value for the price.

Fast shipping and well packaged

Arrived quickly and each bearing was individually wrapped. No rust or debris. Exactly as described.

Good value, minor packaging issue

The bearings themselves are excellent. One box was slightly dented during shipping, but the parts inside were fine.

Reliable for robotics

I use these in several robotic arms. The flange makes mounting easy and the tolerance is consistent across the batch.

5 FAQ

Q: What is the maximum RPM for the 10mm size?

A: The 10mm inner diameter model can safely operate up to 28,000 RPM under standard load conditions.

Q: Can these be cleaned and re-lubricated?

A: Since these are ZZ sealed, removing the shields may damage them. We recommend using them as supplied.

Q: Do you offer bulk discounts for over 100 boxes?

A: Yes, please contact our sales department directly for volume pricing on large industrial orders.

Q: Are these bearings suitable for outdoor use?

A: They are chrome steel with seals, but for prolonged outdoor exposure, we recommend additional corrosion protection.

Q: Is the flange thickness standard across all sizes?

A: The flange thickness varies slightly by inner diameter to maintain structural integrity. Please check the spec sheet.
