Two parallel guide shafts (4)
together with a special guide profile (7), form the body of the RK Compact linear unit.
The rotating movement of the spindle (3) with the
corresponding guide nut (6) is converted into a linear
movement of the guide table (9).
The spindle of the RK Compact
30 is protected from dust
by a surrounding PUR cover (see drawing). |
