Good quality, slow shipping
The bearings themselves are top notch and fit perfectly. Only downside was the shipping took a week longer than estimated.

Packaging needs improvement
One bearing seal was slightly bent upon arrival due to thin packaging. The bearing still works, but care needed during unpacking.

Excellent corrosion resistance
Used these on a marine winch system. After six months of saltwater exposure, there is no sign of rust. Smooth operation still.

Quiet operation for 3D printer
Replaced standard steel bearings with these S6900ZZ. The noise level dropped significantly and movement is very smooth.
Q: Can these withstand high heat environments?
A: The standard grease allows operation up to 120°C. For higher temperatures, high-temperature lubrication is required.
Q: Is this genuine German BKD stock?
A: Yes, we import directly from BKD Germany and provide certificates of authenticity upon request.
Q: Are the 440 grade bearings magnetic?
A: Yes, 440 stainless steel is magnetic, whereas 304 grade is generally non-magnetic.
Q: What is the dynamic load capacity for S6901?
A: Please refer to the technical datasheet provided in the download section for specific load ratings per model.
Q: Do these come pre-lubricated?
A: Yes, all bearings are pre-lubricated with food grade grease suitable for general purposes.
