SKF profile rail LLTHR

For mounting from above

The SKF profile rail LLTHR is provided with pre drilled holes by default. These holes enable you to mount the LLTHR from above. The LLTHR is supplied with protective plastic caps as standard. The X-arrangement allows the carriages to run very smooth because it decreases the amount of friction between carriage and rail. The key feature of this X-arrangement is that there are only two points of contact in an angle of 45º between rail and carriage. The LLTHR is available in sizes between 15 and 45 mm and in different lengths. There are three different accuracy classes available for each size.

If you are unsure which size or implementation is the most appropriate for you, the differences are written below. If you are still in doubt you can always contact us on +31 (0)85 – 0661258.

Accuracy classes

Accuracy classes

The Accuracy class define the maximum permissible tolerance range of rail system in terms of height, width and parallelism. This choice determines the positioning accuracy of the system within the application. There are three different accuracy classes available for each carriage:

  • P5 – standard: ± 100 µm height- and ± 40 µm width tolerance.
  • P3 – medium: ± 40 µm height- and ± 20 µm width tolerance.
  • P1 – heigh: ± 20 µm height- and ± 10 µm width tolerance.
