support unit can be used in the fixed end and the support end of the screw respectively to fix the screw inn the correct position.
The support unit used in fixed end of the screw is a pair of angular ball bearings in face-to-face arrangements (DF), which can effectively carry axial load of the screw. Due to its face to face arrangement, the unit can absorb calibration
of the screw for the convenience of assembly.
As the support unit used by support end of
the screw is adopted 6 series deep groove
ball bearings, which can effectively support
the screw and control screw radial a
stable position.
