THK SHS-20V1SS(GK) Linear Guide Bearing Block

The THK SHS20V1SS(GK) Linear Guide Bearing Block is a standard-width V-type block from THK’s SHS-V Caged Ball LM Guide family, sold as the bearing block only (rail not included) for precise linear motion in automation systems. It accepts 20 mm guide rails and uses caged ball technology to deliver smooth, low-friction, high-rigidity movement with four-way equal load capability and a self-adjusting design for long service life. Key dimensions include a block width of 44 mm, height 30 mm, and length 79 mm, with mounting bolts from above (M5) and a grease nipple at 45 degrees (B-M6F). Seals are SS type (end, side, and inner seals), and the body is made from carbon steel. The Basic Dynamic Load Rating is 22.3 kN and the Basic Static Load Rating is 38.4 kN, underscoring its suitability for high-precision positioning tasks. Typical applications cover CNC machine tools, electronics manufacturing equipment, pick-and-place and semiconductor production equipment, automated packaging machinery, medical devices, material handling systems, and general factory automation where accurate, repeatable linear motion is essential. Maintenance teams and system integrators rely on this block for machine repair, automation retrofits, linear motion upgrades, and replacement of worn components in machine tools.
