Optimal for use in a vacuum environment where oil cannot be used.
A special oil-free LM guide optimized for use in high vacuum environments where oil cannot be used. It utilizes a newly developed fixed lubrication S film for the rolling elements. Additionally, since no grease is used and all components are made of stainless steel, it achieves low outgassing and low dust generation.
Achieving a smooth movement with minimal rolling variation.
The ball is held in a cage with a spherical ball holder, and the ball rolls on the rolling surface of the four-row circular arc groove of the precision ground LM rail and LM block.
Achieving high-precision and stable linear motion.
The balls roll on the precision-ground rolling surfaces of the four-row LM rail and LM block, and the ball rows are circulated by the ball retainer and the end plate incorporated in the LM block. Each ball row is arranged at a contact angle of 45° to ensure a constant equivalent load in four directions (radial, reverse radial, and lateral) acting on the LM block, allowing for use in any posture while applying a well-balanced preload. This maintains a consistently low friction coefficient while enhancing rigidity in all four directions. With a low cross-sectional height and a high-rigidity design of the LM block, high-precision and stable linear motion can be achieved.
High rigidity LM guide that enables excellent high-speed performance.
The balls roll on the four-row rolling surfaces that are precisely ground on the LM rail and LM block, and the ball rows are circulated by the ball retainer and the end plate incorporated in the LM block. The adoption of this ball retainer enables a wide, high-rigidity LM guide that is low-noise, maintenance-free for a long period, and offers excellent high-speed performance.
Smooth operation with low friction due to the adoption of roller retainers.
The adoption of roller retainers enables low friction and smooth operation, achieving long-term maintenance-free performance in this ultra-high rigidity roller guide.
The structure of X-Y motion has been simplified and made more compact.
The balls roll on the precision-machined four-row rolling surfaces of the LM rail and LM block, and the ball rows are circulated by the ball retainer and the end plate incorporated in the LM block. This is an integrated LM guide that has a similar internal structure to the proven LM guide SHS type with a ball retainer, arranged in a cross shape with the backs aligned, combining two LM rails. The SCR type allows for a perpendicular linear motion system without the need for a conventional saddle, simplifying the structure of the X-Y motion and enabling compact design.
The "Retainer" technology developed by THK, the first in the world.
THK, which developed the world's first LM guide, created a LM guide with retainers that dramatically improves the performance of conventional products, achieving long life, high speed, and long-term maintenance-free operation, similar to rolling bearings.
A new LM guide with improved dustproof performance, designed for machine tools, featuring a heavy load and high rigidity type.
The SVR/SVS type has high rigidity and load capacity among the LM guide series with ball retainers. Furthermore, by enhancing dust-proof performance through a wide range of options considering the usage environment of machine tools, we have achieved the maintenance of LM guide performance and high reliability.
LM guide with ball retainer that achieves ultra-high rigidity.
The LM guide with ball retainers in the SPR/SPS series, which achieves ultra-high rigidity surpassing roller guides and low waviness comparable to static pressure guidance, is newly introduced.
Experience it! With the "Ball Retainer Effect," enjoy high speed, long lifespan, and low noise!
LM guides are products that have realized the rolling of linear motion components, achieving high precision, high rigidity, labor-saving, high speed, and long lifespan in machinery. LM guides with ball retainers eliminate mutual friction between balls by adopting ball retainers, resulting in low noise, good sound quality, long-term maintenance-free operation, and excellent high-speed performance. We offer a diverse lineup including: - World standard size "SHS" - Radial type "SSR" - Wide rail "SHW" - Miniature "SRS" - Ultra heavy load for machine tools "SVR/SVS" - Ultra low waviness and ultra high rigidity "SPR/SPS" For more details, please contact us or refer to our catalog.
Achieving ultra-low waviness and ultra-high rigidity!
To achieve ultra-low waviness and ultra-high rigidity that surpass conventional LM guides, we have adopted eight rolling grooves, small-diameter balls, and ultra-long blocks. This significantly increases the effective number of balls while minimizing the amplitude caused by the entry and exit of the balls. We have achieved ultra-low waviness comparable to static pressure guidance. At the same time, we have minimized the deformation of the balls, achieving ultra-high rigidity that surpasses roller guides. This contributes to the high precision of the equipment.
Heavy load and high rigidity type! Improved dustproof performance, ideal for machine tools!
"SVR/SVS" has high rigidity and load capacity among the LM guide series with ball retainers. Furthermore, by enhancing dust-proof performance with a variety of options considering the usage environment of machine tools, we have achieved the maintenance of LM guide performance and high reliability.
