Solid Choice
Fitment was perfect for the S6902 model. Price is slightly higher than domestic options but worth it for the durability.

Excellent Precision
Used these for my CNC spindle upgrade. The runout is minimal and they operate very smoothly at high RPMs. Genuine German quality.
Q: What is the difference between S6900 and S6901?
A: The difference lies in the inner and outer diameter dimensions. Please refer to the size chart for specific measurements.
Q: Can I use these bearings in submerged water applications?
A: While stainless steel resists rust, these are not specifically sealed for submerged use. We recommend protective housing for water exposure.
Q: What is the maximum RPM for the S6903 model?
A: The limiting speed varies by lubrication and load, but generally, this series supports up to 30,000 RPM under ideal conditions.
Q: Are these bearings corrosion resistant?
A: Yes, they are made from 304 Stainless Steel which offers excellent resistance to rust and corrosion in most environments.
Q: Do they come pre-lubricated?
A: Yes, all bearings are pre-lubricated with high-speed grease suitable for general industrial applications.
