Efficiency of the Linear guide Rails

When it comes to linear motion, the precision, the surface condition and a high hardness value are critical parameters. Indeed, in the current industrial context, automation has reached a level of integration that requires high performance, consistency and reliability. Linear motion technologies must operate under heavy loads with no damage to the raceways over the course of its lifetime usually materialized by millions of accurate strokes of a carriage rolling along a precision guide rail.

At Swiss Profile, strong from our experience in cold forming of metal profiles, we are reputable for the smoothness of the surface, the precision and the accuracy of the shape, especially in high quality composition bearing steels and stainless steels that are specifically catered for extremely tough applications. We are now extending our knowhow and our offer on the market with the integration of our continuous hardening equipment that allows us to produce long hardened high-precision profiles for linear guide rails. The high-quality surface of a cold rolled profile along with the high hardness are both essential to ensure the reliability and durability of assemblies in motion.

Rather than creating a case-hardened surface, our continuous hardening process under protective atmosphere followed by a tempering operation at low temperature confers to the linear profiles the desired dimensional stability. This heat treatment will result in an improvement of the mechanical properties, producing a tougher and more durable profile while relieving the brittleness of fully hardened steel or stainless steel. In properly sized linear bearings, typical life ratings range from hundreds to thousands of kilometers of travel.

Our precision profile and wire races are custom made in various shapes and cross sections to be mounted on base plates, embedded into aluminum rails or directly used as rails depending on the applications and requirements. We offer an extensive product lineup that can be produced in any length up to 6m in a hardness range of 50HRC to 60HRC.
