Shaft Support Rail Units

Shaft support rail units are essential for ensuring full stability along the entire length of the precision shaft. By providing continuous support, they effectively eliminate deflection and increase the overall rigidity of the system. These units are particularly well-suited for dynamic applications where low weight and high guiding precision are critical.

All dimensions in the table are provided in [mm], unless otherwise specified.
Depending on the length of the precision shaft, the shaft support unit may consist of multiple segments.
For version P1, maximum single support unit length LMAX = 1500 mm
T5,T6 = min. 20 mm
1) Upon request, LMAX = 3700 mm.
2) Maximum length of a single support unit
3) Weight specified without shaft
