description
- To meet the requirements of the servo-controlled machinery field, Torrington has developed a new series of ball bearings specially designed for ball screw applications. Design criteria for these bearings with maximum axial rigidity, low drag torque, and extreme control of lateral eccentricity.
applications
- Ball screw support
features
- Pre-lubricated with high-performance grease
- Broad availability for increased machine uptime
- ABEC 9/ISO P2 axial running tolerances for higher accuracy
- Tighter preload tolerances for chatter-free cutting
- Tighter width tolerances for easy fit without regrinding end caps
- Clean steel supports longer service life
caution
- Should not be used in other areas such as spindles or gearbox shafting without approval by Torrington Engineering Department.
