NEW THK SHS45C1SS(GK)

The THK SHS45C1SS(GK) is a Size 45 Caged Ball LM Guide Block from THK's Global Standard SHS Series. It features a C-Style flanged block with tapped holes, enabling mounting from both the top and bottom surfaces, making it ideal for applications where through-holes for bolts are not possible. The block is ordered separately from the rail (GK designation) and includes End Seals plus Side Seals (SS) for contamination protection.
The SHS series uses THK's caged ball technology with four rows of precision-ground raceways and a 45° contact angle, providing equal load capacity in all four directions (radial, reverse-radial, and lateral). The self-adjusting block design absorbs mounting errors even under preload, delivering highly accurate, smooth, and quiet linear motion with extended service life.
