Solid construction
Heavy duty feel. The double notched flange makes mounting very secure. Would buy again for future linear motion projects.

Perfect for CNC build
These bearings fit perfectly on my linear shafts. The motion is smooth and there is no binding. Highly recommend for hobbyist CNC projects.

Good quality but tight fit
Quality seems solid. The 8mm version was slightly tight on my shaft initially but loosened up after some use. Good value overall.

Fast shipping and well packed
Arrived earlier than expected. Each bearing was individually wrapped to prevent damage. The flange holes aligned perfectly with my mounts.

Been using these in an automation rig for three months now. No wear visible and still running quietly. Very satisfied with the purchase.
