Product Overview

Rolling-element guideways are linear motion components using recirculating steel balls or rollers between a rail and sliding carriage. They are integrated into CNC lathes, machining centers and feed-axis assemblies for repetitive positioning in metal-cutting and automated machining equipment.

Key Features

Ball Contact for Light Moving Masses

The ball-type guideway is specified for loads up to 40 kN and running speeds up to 60 m/min. On a small CNC slide repeatedly positioning a light toolholder between short cutting passes, point-contact rolling elements reduce the driving force needed for reversal.

Roller Contact for Transverse Loads

The roller-type alternative covers the published 60–120 kN load range. When a machining-center saddle is exposed to sideways forces from an offset face mill, cylindrical rolling contact distributes the load over a larger contact line and limits elastic movement.

Automatic Lubricant Delivery

The system uses timed automatic lubrication to supply the rail and carriage contact surfaces. During extended multi-shift axis cycling, metered lubrication prevents dry metal-to-metal contact inside the recirculation path and helps maintain uniform carriage motion.

Custom Rolling-element Guideways

We select the rail and block combination from the axis load case, available mounting space and travel requirement. Rail seating and fixing-hole geometry are prepared to match the machine structure, followed by installation and full-stroke sliding checks before the assembled axis is approved.

Quality Control

Guideway mounting faces are checked for flatness, rail-to-rail spacing and parallelism. The blocks are positioned and fastened in a controlled sequence to avoid introducing twist into the axis.

Carriage movement is assessed through the full travel, including changes in movement resistance at rail joints and end positions. Fasteners, seals and oil outlets are inspected again during final assembly checks.
