Our assembly geometry provides better load distribution, enabling superior load and moment capabilities. Roller guides have greater rigidity and load capacity when compared to ball guides, as the contact area between the rollers and the rail's rolling track is a line, different from the ball guide which is only a point of contact .
Our guides are fully interchangeable with the main brands on the market and our engineering team works directly with our customers' maintenance sectors.
We have great expertise with machine manufacturers and an excellent cost-benefit ratio making your machine competitive.

Diferenciais


ETM R series roller guides are made of bearing steel.

Due to its internal V-groove design, our roller guide has a high torque capacity.

Linear roller guides are indicated in linear systems with high movement precision, rigidity and very high loads.

Our roller skates have a cage between the rollers, allowing increased operating speeds; Decreased working temperature and increased service life.

The lubricating grease stored in the cage allows for longer periods between lubrications, reducing costs with extended service life.

2D and 3D specifications

The oil layer between the roller and the cage significantly reduces friction, generating less heat during work, ensuring high speed and high precision in movement.

The contact angle between roller and track is 45°, allowing the linear roller guide to be equally loaded in all four directions.

All ETM roller guide models have a cage between the rollers to keep them separated, avoiding collisions and thus eliminating any noise. It also makes the rollers move straight and stable.
