Abstract
A linear guiding unit comprises a guide housing (10). Inside the guide housing (10) there are provided linear ball bearings by which a carriage (40) is guided. Moreover, a pneumatic drive (56) is accommodated within the guide housing (10). The pneumatic drive comprises a cylinder cavity (58) inside the guide housing (10). The cylinder cavity (58) accommodates a piston (60). The piston (60) is movable along the cylinder cavity (58). The piston (60) is connected with the carriage (40) by a flexible rope (74). This flexible rope is sealingly passed through cover walls (66) of the cylinder cavity (58). The rope is deviated outside the cylinder cavity (58) and is fixed to the carriage (40). A cover belt (90) different from the rope covers a longitudinal opening (31) of the guide housing (10) through which the carriage can be connected with an object for common axial movement.
