Mechanical Linear Drive Unit WIESEL FORCELine
The power bridge (7) is used as assembly and mounting
surface for the load to be moved. The scraper brushes
(4) mounted on the sliding carriage remove coarse dirt
from the surface of the tubular section (9).
The tubular section serves as a protection for the ball
screw (1) and as a guideway for the screw supports (10)
and to receive the guideways (11). Flexible sealing strips
(3) cover the upper tube opening in front of and behind
the power bridge.

ducts (see Chapter 8 "Lubrication").
In addition to the limit switches that can be read off by
the controls, adjustable electromagnetic safety limit
switches can be added on for both end points (see
Chapter 4 "Adjusting the maximum length of travel").
