This is an LM guide with ball retainers, optimized for ultra-heavy loads and high rigidity, suitable for machine tools.
The adoption of roller retainers enables low friction and smooth operation, achieving long-term maintenance-free performance. 【Ultra High Rigidity】 By using high-rigidity rollers for the rolling elements and ensuring that the total length of the rollers is more than 1.5 times the roller diameter, even higher rigidity is achieved. 【Four-Way Equal Load】 The roller rows are arranged at a contact angle of 45 degrees to ensure that the same rated load acts in four directions (radial, reverse radial, and lateral) on the LM block, providing high rigidity in all directions. 【Smooth Operation Preventing Skew】 The roller retainer ensures that the rollers are uniformly aligned and circulate, preventing skew (tipping) of the rollers when entering the block load area, resulting in small fluctuations in rolling resistance and stable, smooth operation. 【Long-Term Maintenance-Free】 The roller retainer eliminates mutual friction between rollers and improves grease retention, achieving long-term maintenance-free performance. 【Thin and Low Center of Gravity】 The total height has been reduced for the LM guide SRG type with roller retainers, making it ideal for compact designs.

basic information
【Lineup】 ● SRN-C Type The flange part of the LM block is tapped for mounting. It can be installed from either the top or bottom. It is used when it is not possible to drill through holes for mounting bolts on the table. ● SRN-LC Type This type has the same cross-sectional shape as the SRN-C type but has a longer LM block length L, increasing the rated load. ● SRN-SLC Type This type has the same cross-sectional shape as the SRN-LC type but has a longer LM block length L, increasing the rated load. ● SRN-R Type This type has a narrower width W for the LM block and is tapped. It is used in areas where there is no space on the table width. ● SRN-LR Type This type has the same cross-sectional shape as the SRN-R type but has a longer LM block length L, increasing the rated load. ● SRN-SLR Type This type has the same cross-sectional shape as the SRN-LR type but has a longer LM block length L, increasing the rated load. Size range: SRN35 to SRN65
