Wide Rail LM Guide 'SHW' with Ball Retainer: THK

Wide Rail LM Guide 'SHW' with Ball Retainer: THK

The LM rail is a four-directional equal load type LM guide with excellent Mc moment due to its wide low center of gravity structure.

This is a wide-type high-rigidity LM guide that enables low noise, long-term maintenance-free operation, and excellent high-speed performance due to the adoption of a ball retainer. 【Wide and Low Center of Gravity】 The SHW type, with its wide LM rail and low center of gravity structure, is optimal for locations where space-saving is required and where MC moment rigidity is necessary. 【Four-Directional Equal Load】 Each row of balls is arranged at a contact angle of 45 degrees to ensure that the load acting on the LM block is the same in four directions (radial, reverse radial, and lateral), allowing for use in any orientation and making it suitable for a wide range of applications. 【Automatic Adjustment Capability】 Thanks to THK's unique circular arc groove front combination (DF set), the automatic adjustment capability allows for the absorption of mounting errors even when preloaded, resulting in high-precision and smooth linear motion. 【Low Dust Generation】 The ball retainer eliminates mutual friction between the balls and retains the lubricating oil (agent), resulting in excellent low dust generation properties.

Ball Retainer Ultra Heavy Load LM Guide 'SVR/SVS': THK

Ball Retainer Ultra Heavy Load LM Guide 'SVR/SVS': THK

This is a linear motion guide with ball retainers, optimized for ultra-heavy loads and high rigidity, suitable for machine tools.

This is a super heavy load, high rigidity type that is optimal for machine tools, featuring high rigidity and load capacity among the ball retainer LM guide series. ● Improved super heavy load and damping Adopting a circular arc-shaped deep groove. As the load increases, the ball contact area expands, allowing for greater load capacity and further improving damping (dissipation). ● High rigidity Achieves high rigidity among ball retainer LM guides. Additionally, offers radial type SVR and four-direction type SVS in the same dimensions. ● Enhanced dustproof performance and abundant options The newly developed protector improves foreign object removal functionality and strengthens dustproof performance. Furthermore, by adopting side scrapers, it reduces the intrusion of foreign objects into the LM block, maintaining the performance of the LM guide over a long period even in harsh environments. ● Abundant options Provides various options such as end seals, inner seals, side seals, laminated contact scrapers (LaCS), protectors, side scrapers, and GC caps, enabling compatibility with various usage environments. ● Mounting compatibility Compatible with the mounting dimensions of SNR/SNS types.

Super high rigidity LM guide 'SRN' with roller retainer: THK

Super high rigidity LM guide 'SRN' with roller retainer: THK

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.

Ultra-low waving ultra-high rigidity LM guide 'SPR/SPS': THK

Ultra-low waving ultra-high rigidity LM guide 'SPR/SPS': THK

New realm of LM guides. Achieved ultra-low waviness and ultra-high rigidity that surpass conventional LM guides.

The SPR/SPS shape has a waviness value of about 1/10 compared to conventional general LM guides (100-300nm). To achieve ultra-low waviness and ultra-high rigidity that surpass conventional LM guides, it employs eight rolling grooves, small diameter balls, and ultra-long blocks. With a significant increase in the number of effective balls, the amplitude caused by the entry and exit of the balls is minimized, achieving ultra-low waviness comparable to static pressure guidance. At the same time, the deformation of the balls is minimized, achieving ultra-high rigidity that surpasses roller guides. This contributes to the high precision of the equipment.
