Curviline products:

Constant radii
The layout of CKR guide rails corresponds to a partial section of a complete circle.

Variable radii
CVR curvilinear rail is a variable combination of various radii and straight partial pieces.

The carriage maintains desired preload over the entire rail layout. Moving roller mountings and the paired application of concentric and eccentric roller pins ensures uniform running even with a complex rail layout.
