The ball screw support seat is the bearing support seat that supports the connecting screw and the motor. The support seat is generally divided into: fixed side (after K to indicate such as BK12) and support unit installation (with F to indicate such as BF12), both of which are adjusted by preload JIS5 grade angular contact ball bearings.
The ball screw support seat is equipped with an ultra-small angular contact ball bearing with a contact angle of 45 degree developed for an ultra-small ball screw, which can obtain 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 and BK type internal bearings are filled with a proper amount of lithium soap-based grease, sealed with special sealing gaskets, which can be directly installed and used for a long time.
(1) Adoption of the best bearing
Considering the balance of rigidity with the ball screw, high rigidity and low torque angular contact ball bearings (contact angle 30 degree , free combination) are used. At the same time, the ultra-small support units EK6 and 8 are equipped with ultra-small angular contact ball bearings developed for ultra-small ball screws. The contact angle of this kind of bearing is 45 degree , the ball diameter is small, and the number of balls is large. It is an ultra-small angular contact ball bearing with high rigidity and high precision, which can obtain stable rotation performance.
(2) The shape of the support unit
The supporting unit has angle type and round type series, which can be selected according to the application.
(3) Small and easy to install
The support unit is a small volume design that takes into account the space around the installation. At the same time, the adjusted and preloaded bearing is installed, and the assembly can be directly carried out after delivery, which not only reduces assembly man-hours, but also improves assembly accuracy.
