Ballscrew Support Units

The ball screw support bearing fabricated by us are precision engineered high ability bearings. These ball bearing are designed with polyamide cages and so that bearing stiffness are greater than conventional bearing. Our bearing are supplied with a pre-set preload so complicated adjustment and measurements are removed. Features

• Compact
• Robust Design
• Corrosion Resistance
• Reliability

This BF type ball screw support bearings are manufactured with poly amide so that bearing stiffness is greater than conventional bearings. These bearings have a 60 contact angle so that radial and thrust load combination can be sustained. We also provide our clients with flush ground set combination bearings which are also available with suffix U. This permits the use of random combination where two or more bearings are mounted. These are used at actuators of high precision and high speed machines, precision measurement equipment, robots etc.
