Overview
The THK SR25W1SSGKBLOCK is a stainless steel linear motion guide block designed for the SR25 series LM guide rail system. Balls travel in four precision-ground raceways on an LM rail through the LM block, with endplates incorporated in the LM block. This model is the stainless steel variant of the SR series, making it suitable for environments requiring corrosion resistance and durability. The THK SR25W1SSGKBLOCK delivers precision linear motion with self-adjusting capability for mounting flexibility.
Key Features
- Each row of balls is placed at a contact angle of 45° enabling the rated loads applied to the LM block to be uniform in all four directions (radial, reverse-radial and lateral directions) for constant low friction coefficient and increased rigidity.
- Blocks self-adjust enabling mounting error to be absorbed, even under preload, for highly accurate, smooth linear motion.
- Stainless Steel Construction: Corrosion-resistant material suitable for harsh or wet environments.
- Low profile design saves space and includes pre-tapped screw holes and bolts for installation.
- Full-ball type design for multi-directional load capacity and operational flexibility.
Technical Specifications
The SR25W1SSGKBLOCK is designed to integrate seamlessly with THK SR25 guide rail systems. Standard specifications for the SR25 series include moderate load ratings suitable for precision automation equipment.
