THK SR20V1SS-GK Linear Bearing Block For LM System

The THK SR20V1SS(GK) Linear Bearing Block is a compact radial-type carriage for THK SR20 LM Guide rails, delivering precise, low-friction linear motion with excellent rigidity. Its self-adjusting four-row ball raceway supports high radial loads and smooth travel, making it ideal for CNC tooling, semiconductor equipment, robotics, packaging machinery, precision measurement devices, and automated production systems. The block is a compact V-type design configured for 20 mm rails, with overall dimensions: height 28 mm, width 42 mm, length 47.3 mm; block width 32 mm; mounting thread M5×8 mm. It provides dynamic load rating 13.4 kN and static load rating 17.2 kN, with SS seals (end, side, inner) for improved contamination protection. Constructed from stainless steel and suitable for grease or oil lubrication, it operates from -20°C to 80°C. This bearing block is favored by maintenance teams and system integrators for OEM replacement, machine repair, retrofit projects, and new precision linear-motion assemblies. The SR20V1SS(GK) combines compact form with reliable guidance for applications demanding precise positioning, long service life, and quiet operation.
