1. Fitted with specially designed semi-precision bearings, this roller is light and runs smoothly.

2. The ball bearing tolerance is greater than a precision ball bearing. These rollers have the ability to withstand higher impact loads than other series rollers.

3. The environmental working conditions are broad. They can be used in both high and low temperature applications. 

4. Anti-static design.

5.Slightly higher noise levels compared with precision ball bearings.

6.Cannot be used as belt conveyor idlers and friction belt conveyor.

7.Temperature range: - 20℃ ~ + 80℃.

Note: Not suitable for carring roller&tensioning position of belt conveyor.
