basic information
[Features] ○ Improved heavy load capacity and damping → The "SVR/SVS" adopts a circular arc-shaped deep groove with a curvature approximating the ball diameter on the rolling surface. As the load increases, the contact area with the balls expands, resulting in a greater load capacity and improved damping characteristics. ○ Enhanced dust resistance → The newly developed protector enhances foreign object removal functionality, strengthening dust resistance. Additionally, the adoption of side scrapers reduces the inflow of foreign objects into the LM block, maintaining the performance of the LM guide over a long period even in harsh environments. ○ High rigidity → The "SVR/SVS" achieves high rigidity among LM guides with ball retainers. Furthermore, it offers a lineup of radial type "SVR" and four-direction type "SVS" in the same dimensions, allowing for selection based on specifications. ○ Abundant options → A variety of options are available, including end seals, inner seals, side seals, layered contact scrapers (LaCS), protectors, side scrapers, and GC caps, enabling compatibility with various operating environments.

Detailed information
-
"SVR-R / SVS-R" is a type with a narrower width (W) of the LM block and has been subjected to tapping. It is used in areas where there is no space for the table width.
-
"SVR-LR / SVS-LR" is a type that has the same cross-sectional shape as "SVR/SVS-R," but with a longer LM block length (L) and increased rated load.
-
"SVR-C / SVS-C" The flange part of the LM block has been tapped. 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.
-
"SVR-LC / SVS-LC" is a type with the same cross-sectional shape as "SVR/SVS-C," but with a longer LM block length (L) and an increased rated load.
-
"SVR-RH/SVS-RH" The height (M) and width (W) dimensions conform to the "SHS" HSR type, and it is a type that has been tapped on the LM block.
-
"SVR-LRH/SVS-LRH" is a type that has the same cross-sectional shape as "SVR/SVS-RH" but with an extended full length (L) of the LM block, increasing the rated load.
-
"SVR-CH/SVS-CH" The height (M) and width (W) dimensions are based on "SHS" and "HSR," and this type has been tapped on the flange part of the LM block.
-
"SVR-LCH/SVS-LCH" is a type that has the same cross-sectional shape as "SVR/SVS-CH" but with a longer LM block length (L) and an increased rated load.
