SKF profile rail LLTHR D4For mounting from below
The SKF profile rail LLTHR D4 is provided with blind holes by default. These holes enable you to mount the LLTHR D4 from below.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 D4 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.
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.
