App. Example

■Slide Base Transfer Unit
■Recommended Configuration
This unit allows the slide base for workpiece/fixture loading to be position-adjusted
by manually rotating its lead screws. A dedicated lead screw, bearing unit and stopper clamp are combined
in a set.
The unit can support radial and axial loads, and can be constructed more economically in a compact manner
. Also, position indicators can be easily mounted.
