Ultra-high Rigidity (Low center of gravity) Model SRN

Interchangeable with LM Guide model SNR, which is designed for machine tools.

The SRN is an ultra-high rigidity Roller Guide that uses roller cages to lower friction, operating noise, smooth motion and extend the units maintenance-free service life. Roller cages also reduce rolling resistance fluctuation, prevent rollers from skewing as the block enters a loaded area and facilitate smooth and stable motion.

Interchangeable with the SNR LM Guide which is designed for machine tools, it has a lower total height than the SRG Model making it ideal for compact designs. The SRN achieves a high rigidity through the use of highly rigid rolling elements and an over-all roller element length of more than 1.5 times greater than that of the roller diameter.

A 45 degree roller contact angle ensures that the LM block receives an equal load rating in the radial, reverse radial and lateral directions.

The Advantage of Linear Guide

High Accuracy
Because linear guide has little friction resistance, only a small driving force is needed to move the load. Low frictional resistance helps the temperature rising effect be small. Thus, the frictional resistance is decreased and the accuracy could be maintained for long period than traditional slide system.

High Rigidity
The design of Linear Guide rail and block features an equal lead rating in all four directions that request sufficient rigidity load in all directions, and self-aligning capability to absorb installation-error. Moreover, a sufficient preload can be achieved to increase rigidity and makes it suitable for any kind of installation.

Easy for Maintenance
Compared with high-skill required scrapping process of traditional slide system, the Linear Guide can offer high precision even if the mounting surface is machined by milling or grinding. Moreover the interchangeability of Linear Guide gives a convenience for installation and future maintenance.

High Speed
Linear Guide block, rail and ball apply by contact point of Rolling system. Due to the characteristic of low frictional resistance, the required driving force is much lower than that in other systems, thus the power consumption is small. Moreover, the temperature rising effect is small even under high speed operation.

High Performance without Clearance
Even under a preload or regular load, the ball and raceway contact one another at two points in the loading direction, as shown. This design gives rise to a smooth rolling motion.
