How To Look At The Bearing Seat Of The Support Seat When The Ball Screw Is Applied

The bearing seat is usually a supporting product that needs to be used for the ball screw. It is the core component of it. It has a fixed side and a support side. , BF, EK, EF and circular FK, FF.

   P5 DF (face-to-face) angular contact ball bearings are used on the fixed side of the ball screw support, with zero clearance for preload adjustment. The support seat of the ball screw support seat uses deep groove ball bearings. For the accuracy of the ball screw used, the corresponding supporting seat is usually selected when the support seat is selected. The center height of the ball screw support seat, bearing accuracy, and bearing installation hole accuracy determine the accuracy of the screw support seat. If the specified requirements are not met, there will be abnormal phenomena such as shaking and noise during operation.

The main body, angular contact ball bearing, gland, and oil seal of the ball screw support seat are integrated. Unfamiliar people should not disassemble it without authorization. Professionals should use special methods to assemble it.

There are generally two spacers and a special lock nut on the fixed side of the ball screw support seat.

The ball screw support seat has deep groove ball bearings and angular contact ball bearings. Their contact angles are different. The contact angle of deep groove ball bearings is 0°, while the contact angle of angular contact ball bearings is greater than 0°, generally 15°. 25°, 30°, etc. Angular contact ball bearings can bear both axial and radial loads, while deep groove ball bearings mainly bear radial loads. Angular contact ball bearings of the same size are usually used in combination in three ways, back-to-back, face-to-face, and parallel. Angular contact ball bearings generally have single ribs on both sides of the outer ring channel, while deep groove ball bearings have double ribs.
