LFS-12-3 Linear Rails and Bearings

Click image to enlarge

The LFS-12-3 linear rail can be combined with several different carriage options to handle applications where a single wider rails is needed due to cantilevered loads.
Two 12mm diameter steel rails are supported uniformly through the length of travel by a clear anodized 90 mm wide aluminum support profile
Guide rails consist of two precision GERMAN ground Ø12 mm h6 steel shafts with M5 threaded holes spaced 100 mm apart.
The shafts are hardened to RC62 +2 for durability against heavy loads and virtually no wear
The double rail and support profile is sold as a complete assembly in lengths from 400 mm to 3000 mm
Longer lengths with staggered rails are available on special order. 3m sections can be joined to make virtually any required length rail.
The support profile has mounting holes 75 mm apart at 100 mm intervals along the system length. This allows for QUICK MOUNT to our Heavy-Duty Extrusion Plates or other mounting surfaces.
MADE IN GERMANY!
