Low-profile guide for linear motion

Edited by the Engineeringtalk editorial team Jul 17, 2002

In the wake of the success of the Super Roller Guide (SRG) linear motion system, THK has launched the SRN LM guide - specifically designed for applications that require low-profile guidance.

In the wake of the success of the Super Roller Guide (SRG) linear motion system, THK has launched the SRN LM guide - specifically designed for applications that require low-profile guidance.

Featuring THK's caged roller system, the new SRN LM guide features all the benefits associated with the SRG LM guide such as ultra-high rigidity and load capacity, while being suitable for installation in machine tools such as lathes, grinding machines and compact CNC machining centres, where space is often an issue.

The SRN LM guide's compact dimensions allow for additional construction around the unit.

This provides greater stiffness, improving rigidity of the machine, while ensuring the designated machine area remains the same.

Designed to provide users with smooth movement through low-rolling resistance, the roller geometry and retainer are crucial in ensuring that the rollers provide streamlined movement without skewing offering minimum roller resistance variation and improved smoothness of movement, leading to better component surface finish.

The design also allows for high-speed performance, giving higher productivity with a significantly lower noise level than competing guides.

Separated by the cage, the rollers are not in contact with each other, eliminating metallic noise.

Furthermore, the SRN LM guide's roller retainer, with a grease pocket between the elements, provides exactly the right amount of lubrication directly where needed, resulting in substantially longer lubrication intervals, making maintenance-free operation a reality for many applications, subject to loading and environmental conditions.

The SRN LM guide is available in sizes ranging from 25 to 65mm.

Standard and even higher capacity longer blocks are available, allowing THK to offer caged technology solutions to many applications.

Supporting the development of more efficient machines, while improving the structural possibilities in mechanical engineering and automation, is at the heart of THK's approach to manufacturing.

It is this commitment to innovation and quality that has ensured THK's reputation as a world leader in linear motion systems.
