K-Rail

STOCK ITEM
The compensation rails are used for the load carrier of radial and axial forces. Tolerance compensation in two planes in combination with the U-rail. A combination of compensating rail and floating rail (K+U system) manages both parallel deviations and angular errors. The unique raceway contour of the K-rail allows the slider a certain rotation around its longitudinal axis, with the same linear precision as with a T-rail. The K-rail must be mounted in such way that the radial load of the slider is always supported by at least 2 rollers on the slider, which lie on the V-shaped raceway of the rail.

The rails are available in 2 different sizes: 43, 63 mm.

Longer single rails up to max. 4080 mm on request. For longer rail systems, see section ”Joined rails” in Technical Information.

Dimensions in mm.

D1 Fixing holes for Torx® screws with low head (custom design) included in scope of supply.
D2 Fixing holes for countersunk head screws according to DIN 7991.
