The structure and specialty of type BLR
Rotary ball screw is a nut rotating ball screw device which integrates nut and supporting bearing. The contact angle of the supporting bearing is 60 degrees and the number of steel balls is increased. It is an axial angular contact bearing with high rigidity.
The BLR type can be divided into two types: precision ball screw and rolling ball screw.
Advantages of type BLR:
1. smooth motion
2. low noise can also be maintained at high speed.
3. high rigidity
5. easy installation
