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.

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.

We provide explanations from the analysis of equipment failure causes to AI predictive maintenance and integrated management!
Stable operation at manufacturing sites is a management issue that affects sales and profits. If equipment stops, production is delayed, leading to serious risks such as missed deadlines and decreased quality. This is why the question of "how to maintain efficient operations and enhance productivity" is always raised. Traditional periodic inspections and reactive measures are insufficient to cope with the advancement of equipment and the complexity of production lines. On-site, there are issues such as prematurely replacing still usable parts, wasting costs, or, conversely, unexpected failures occurring between inspections, causing production lines to halt. In light of the above, "preventing failures and maximizing operational efficiency" is crucial in the manufacturing industry. This article will explain these challenges and their solutions. *For detailed content of the article, please refer to the PDF. For more information, feel free to contact us.*

The adoption of roller retainers prevents roller skew, resulting in low friction and smooth operation, achieving long-term maintenance-free ultra-high rigidity roller guides.
LM guide with ball retainer that achieves lightweight and compact design.
The LM guide SRS type with ball retainers features a structure that incorporates two rows of rolling surfaces within a compact body, allowing it to bear loads in all directions. It can be used in space-constrained areas and locations where moments are applied, all with a single axis. Furthermore, the adoption of ball retainers eliminates mutual friction between the balls, resulting in excellent high-speed performance, low noise, good sound quality, long lifespan, and long-term maintenance-free operation.
Compact and stable linear guide mechanism.
The two rows of rolling surfaces, precisely ground on the LM rail and LM block, allow the balls to roll and circulate through the ball rows, thanks to the end plate incorporated in the LM block. The LM block holds the balls in place with a retaining plate, preventing them from falling out. The two rows of balls rolling on the LM rail have an angular contact structure that makes contact with each rolling surface at a 45° angle. When assembled in the same plane (by combining two LM rails and an LM block used in the same plane), they can bear the same load in four directions (radial, reverse radial, and lateral). Moreover, due to the low profile height, a compact and stable linear guide mechanism is achieved. It is relatively easy to adjust the gaps and has excellent ability to absorb mounting errors.
Low noise, high speed, long lifespan, and long-term maintenance-free are achieved.
The balls roll on the four-row rolling surfaces precisely ground on the LM rail and LM block, and the ball retainer and end plate integrated into the LM block circulate the ball rows. By adopting this ball retainer, mutual friction between the balls is eliminated, and the grease retention capability is improved, resulting in low noise, excellent high-speed performance, and achieving long life with long-term maintenance-free operation.
