Good Quality, Tight Fit
The quality seems solid. They were slightly tighter than expected out of the box but loosened up after some use. Good value for the price.

Arrived quickly and were well packaged. No damage to the flanges during transit. Will buy again for my next automation project.

Excellent Precision
Measured the bore and outer diameter with calipers. All within specified tolerances. The oval flange makes mounting very stable.

Solid Upgrade
Used these to upgrade my 3D printer linear motion. Much quieter than the old plastic ones. Just make sure your shafts are hardened.

Perfect for CNC Build
These bearings fit my 12mm shafts perfectly. The motion is smooth and there is no noticeable play. Highly recommended for hobbyist CNC projects.
Q: What is the maximum operating temperature?
A: The standard operating temperature range is between -20°C to 120°C depending on the lubricant used.
Q: Are the flange mounting holes metric or imperial?
A: All mounting holes follow metric standards corresponding to the bore size selected.
Q: Do I need to add oil before using them?
A: They come pre-lubricated with grease. However, periodic maintenance lubrication is recommended for extended life.
Q: Can these handle vertical load applications?
A: Yes, but ensure the shaft is properly supported to prevent sagging under heavy vertical loads.
Q: Are these compatible with standard hardened steel shafts?
A: Yes, these bearings are designed specifically for use with standard hardened linear steel shafts.
