Exactly as described
Needed 6904 shields for my spindle. Arrived quickly and packaged securely to prevent damage. Very satisfied.

Good but grease is stiff
Bearings are solid quality. The pre-applied grease is a bit thick for high speed, but easy to clean and re-lube.

High quality for the price
Using these in a custom robotic arm. No play in the bearings and they handle the load well. Will buy again.

Perfect replacement parts
Ordered the 6902 size for a motor repair. Fit was exact and rotation is very smooth. Great value for stainless steel.
Q: Can I use these in a wet environment?
A: Yes, being stainless steel they offer good corrosion resistance, but prolonged submersion is not recommended without additional protection.
Q: What is the maximum RPM for the 6903 size?
A: Limiting speed varies by lubrication and load, but generally around 30,000 RPM for grease lubrication under light load.
Q: Do you offer bulk pricing for 100+ units?
A: Yes, please contact our sales team directly through the customer service portal for bulk order quotes.
Q: Are these bearings sealed or shielded?
A: These feature steel shields (ZZ) on both sides. They are not rubber sealed, which allows for higher speed operation.
Q: What is the internal clearance class?
A: Standard internal clearance (CN) is used for these deep groove ball bearings unless otherwise specified.
