Bearing Units is combinations of Insert bearings and housings. ETK ball bearing units provide simple and effective bearing arrangements capable of accommodating moderate initial misalignment from mounting errors. They are easily mounted onto commercial shafting and are particularly useful where fabricated machine frames are employed.

1.Mounting of set screw unit：a. Check accuracy of shaft。Before mounting the bearing unit, check the shaft accuracy for no bends, burrs, and other flawMounting of adapter sleeve unit：NOTE：The adapter sleeve unit can be reliably secured to the shaft even when it is subjected to the impact loads and vi

In order to maitain uniform qualit of materials, FK keeps fully equipped installations and performs strict acceotance tests and inspections based on the strict acceptance standards in addition to JIS-standards.
