Lineærføring

摘要

The linear guide has an interior slot and at least two roll bodies to hold the carriage on the guide rail. The roll bodies are fitted so that they cross each other, enabling the return channels to run through the body of the carriage. There may be channels in plastics bodies, mounted on the carriage and the endface. The carriage runs on steel rails (33-36) fitted in the cavity (6) of the main guide rail, preferably of extruded aluminium strip. They are pushed longitudinally into an undercut groove (37-40) in the strip.
