Ball screws are precision components that convert a rotation into a rotary movement into a linear movement (or vice versa)。 They are increasingly popular in robot technology, machine tool construction, and measuring device technology. The axial angular contact ball bearings, which are manufactured for all dimensions of ball screw drives, are particularly easy to assemble with their adjustable preload The contact angle of these bearings is 60 °. A large number of balls makes these bearings very rigid.
Flush ground set combination bearings are also available with suffix U. This permits the use of random combinations where two or more bearings are mounted. This type is used for supporting the ball screws that are used as actuators of high precision and high machines, precision measurement equipment, robots, etc. This is a precision and high-ability bearing.
High stiffness These bearings are designed with polyamide cages and a greater number of balls than conventional angular contact ball bearings. For these reasons, bearing stiffness is greater than conventional bearings. Easy fitting and adjustment These bearings are supplied with a pre-set preload so difficult adjustment and torque measurement are eliminated.
