The modular Roller Guides feature ease of assembly, high load-bearing capacity, a choice of stroke length and high travelling speed. For easy-running, covered Roller Guides with variable aspect ratios and fastening options. Shaft Clamp Profiles : For connecting Shafts D6, D10, D14 and D25 with the grooves of the corresponding Profile Lines. After pressing the Shaft-Clamp Profile into the profile groove, the Shaft is then pressed in. Bearing Units: For easy-running, covered Roller Guides with variable aspect ratios and fastening options. Bearing Units are used in conjunction with a carriage plate for constructing the sliding carriages. Bearing Units e (eccentric) and c (centric) differ in the geometry of the bolts. The eccentric bolts can be adjusted subsequently so as to ensure that the guide unit is free from play. Bearing Units should therefore always be used in pairs in both centric and eccentric versions.
