Carriage on the basis of door region with built-in bearings in the closed and the open design

摘要

The carriage has a profiled housing with built-in linear bearings in holders, two guide shafts and two support elements for the shafts. On the parallel grooves of a profiled section there are the bearing holders (5) with screws and keyway blocks as support. The bearing holders are tubular, and the bearing surfaces are machined at both ends. for the linear bearing (3). These surfaces prevent the rotation of the holder with the dynamic loading on the carriage. A boss on each holder is used to centre it on the profiled section (1). There is a groove for the centring and fastening to the section. Each bearing holder is open in design. The two guide shafts are parallel and are detachable.
