THK Co., Ltd. SR25V1SS(GK) Block Linear Guide

The THK SR25V1SS(GK) Block Linear Guide is a short-type radial LM block designed for THK SR25 rails, delivering high rigidity and smooth, low-friction motion for precision automation. Built with a four-row recirculating ball raceway and a corrosion-resistant stainless steel carriage, it withstands demanding industrial environments and offers long service life. The carriage measures 59.2 mm long and 48 mm wide, and it carries a dynamic load rating of 11.7 kN with a static load rating of 22.5 kN, making it suitable for precision positioning in compact installations. Compatible with SR25 rails, the block features top mounting, grease or oil lubrication, and a self-aligning capability to accommodate mounting tolerances. It uses SS seals (end, side, inner) for enhanced protection, and is part of the SR-V (GK) series with a V-style short block design. Common applications include CNC machine tools, semiconductor manufacturing equipment, robotics, packaging machinery, precision inspection systems, and automated production equipment, with system integrators frequently selecting it for OEM replacement, machine repair, retrofit projects, and new precision linear motion assemblies. Common replacements include THK SR25W1SS(GK), SR25TB1SS(GK), and SR25SB1SS(GK).
