Good but tight fit
Quality is good, but the fit was slightly tight on my shaft. Needed slight sanding to glide perfectly.

Great for CNC Z-axis
Works smoothly on my router setup. The plastic material keeps noise down significantly compared to metal bearings.

Quiet and durable
No more squeaking during prints. These have lasted several months without any signs of wear.

Solid plastic build
Good for light duty applications. I would not recommend for heavy industrial loads, but perfect for hobbyists.

Exact replacement
Fit my old printer frame perfectly. The flange holes lined up without any modification needed.
Q: What is the total length of the extended bearing?

Q: Are these compatible with hardened steel 8mm shafts?
A: Yes, they are designed to work smoothly with standard 8 mm hardened linear shafts.
Q: Can I use these bearings in an outdoor environment?
