Precision Linear Guideways for Machine Tool Accuracy and Rigidity

Egis

Machine tools demand uncompromising precision, rigidity, and load capacity—and achieving all three starts with the right linear guidance system.

EGIS precision linear guideways utilize needle or cylindrical roller flat cage assemblies without recirculating elements, delivering a fundamentally different performance profile than traditional linear bearings. The result is a compact, high-rigidity linear motion system engineered for applications where accuracy and stability cannot be compromised.

Unlike recirculating linear guides, EGIS systems maintain continuous rolling element contact across the entire motion cycle, ensuring:

This design is particularly advantageous for limited-stroke applications, where traditional recirculating systems can introduce noise, vibration, and reduced precision.

These performance characteristics are well documented in the EGIS system design, where rolling elements remain engaged throughout the full motion path, enabling consistent load distribution and reduced mechanical variation.

With over 50 years of expertise, EGIS (Switzerland) is a global leader in high-precision linear motion technology, specializing in flat cage guidance systems for machine tool and industrial applications.

Their systems are engineered for applications requiring micron-level accuracy, high rigidity, and long-term reliability.

M and V Guideways
Egis M and V Guideways

With Needle or Cylindrical Roller Flat Cage Assembly
M and V guideways are combined with angled flat cage assemblies and are particularly suitable for high load carrying capacities, rigidity, minimal friction and a high level of accuracy.

ML Guideways
Egis ML Guideways

With Adjusting Gib for Needle Roller Flat Cage Assemblies
This series combines an M guideway with an adjusting gib which distributes the preload equally over the entire length of the guidance system.

MVZ Guideways
Egis MVZ Guideways

With Integrated Toothed Rack for Positive Control of the Needle Roller Flat Cage Assembly
In this series, the angled flat cage assembly is subjected to positive control by an integrated toothed wheel/toothed rack unit.

 
M and ML Guideways
Egis M and ML Guideways with Sliding Layer

With Sliding Layer
The guideways in this series consist of an unhardened guideway with a layer fixed by adhesive. They are combined with V guideways and possess the same mounting dimensions as the M/ML and V guideways with flat cage assemblies.

S and J Guideways
Egis S and J Guideways

With Needle Roller Flat Cage Assembly
These guideways are used in combination with needle roller flat cage assemblies as linear non-locating bearings. They are supplied in two versions, one of which possesses a flat, space-saving structure.

LUE Counterstay Systems
Egis LUE Counterstay Systems

With Needle Roller and Cylindrical Roller Flat Cage Assemblies
The LUE Counterstay System consists of a locating guidance system, a non-locating guidance system and an L counterstay which preloads the two guidance systems.

End Pieces, Wipers, Insert Nuts
End pieces prevent the cage assembly from moving out of the loaded zone. Wipers protect the raceways against soiling under normal operating conditions. Insert nuts allow for the transforming of a counterbore into a threaded hole.
