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.

5 FAQ

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.
