The supporting unit on the supporting side uses deep groove ball bearings
The internal bearings of support units EK, FK, and BK are sealed with an appropriate amount of lithium soap based grease and sealed with special sealing gaskets, so they can be used for a long time.
The adoption of the best bearings
Considering the balance of rigidity with ball screw, high rigidity and low torque angular contact bearings (contact angle of 30 degrees, DF combination) were used. In addition, micro angular contact bearings specially developed for micro ball screws are installed in the micro models of EK/FK4, 5, and 6. This bearing has a contact angle of 45 degrees, a small ball diameter, and a large number of steel balls. It is a micro angular contact bearing with high rigidity and precision, which can achieve stable rotational performance.
Shape of supporting unit
There are square and circular series of supporting units, which can be selected according to their purpose.
Small in size and easy to install
The supporting unit is a small structure that takes into account the surrounding installation space. At the same time, due to the installation of pre pressed bearings that have been adjusted, assembly can be carried out directly without further processing. Therefore, it not only reduces assembly time but also improves assembly accuracy.
