What is a ball screw support

The ball screw support is a bearing for connecting the screw and the motor. The structure and the shaft end of the standard ball screw stock are prepared. The standard support unit EK and EF are prepared. The standard support unit BK is prepared for the general ball screw. , BF type. The fixed side support unit is equipped with a pre-stressed JIS Class 5 angular contact ball bearing.

The ball screw support is a bearing support for supporting the connecting screw and the motor. The support is generally divided into: fixed side (plus K for example, such as BK12) and support unit (for F, such as BF12). JIS grade 5 angular contact ball bearings.

The ball screw support seat is equipped with an ultra-compact angular contact ball bearing with a contact angle of 45° developed for the ultra-small ball screw, which achieves high rigidity, high precision and stable rotation performance.

The support unit on the support side uses deep groove ball bearings. Supporting units such as EK, BK type internal bearings are filled with an appropriate amount of lithium soap-based grease, sealed with a special sealing gasket, can be directly installed, long-term use.

(1) Adoption of bearings

Considering the rigidity of the ball screw, a high-rigidity, low-torque angular contact ball bearing (contact angle 30°, free combination) is used. At the same time, the ultra-small support units EK6, 8 are equipped with ultra-compact angular contact ball bearings developed for ultra-small ball screws. This bearing has a contact angle of 45°, a small ball diameter and a large number of balls. It is an ultra-small angular contact ball bearing with high rigidity and high precision, which can achieve stable rotation performance.

(2) Shape of the support unit

The support unit is available in angled and round series, depending on the application.

(3) Small and easy to install

The support unit is a small-sized design that takes into consideration the surrounding space. At the same time, the bearing with the adjusted preload is installed, and the assembly can be directly carried out after delivery, which reduces the assembly time and improves the assembly precision.
