Quiet operation
Replaced the old bearings in my motor. The noise level dropped significantly. Genuine German quality as described.

Great for lathe machinery
Installed these on my industrial lathe. They run smooth and quiet. No vibration issues so far after 2 weeks of heavy use.

Good value for money
Solid bearings. Packaging was secure. Only giving 4 stars because shipping took a day longer than expected.

Fast shipping
Needed these urgently for a repair job. Arrived quickly and fit perfectly into the 6309 housing.
Q: Do these come pre-lubricated or do I need to add oil?
A: All bearings in this catalog come pre-greased from the factory. No additional lubrication is needed upon installation.
Q: How long does shipping take to the US?
A: Standard shipping typically takes 3 to 5 business days. Express options are available at checkout.
Q: Are these compatible with standard 6308 housings?
A: Yes, these bearings adhere to ISO standard dimensions and fit standard 6308 housings perfectly.
Q: What is the difference between ZZ and RS seals?
A: ZZ denotes metal shields on both sides, while RS indicates rubber contact seals. RS offers better dust protection but slightly higher friction.
Q: What is the maximum RPM for the 6307 model?
A: The reference speed for the 6307 is approximately 11,000 RPM, depending on load and lubrication conditions.
