Granite Guide Bar – 40 × 40 mm, 600 mm Length
This precision granite guide bar is manufactured from high-quality black granite and ground to tight tolerances for use in precision motion, metrology, and alignment applications. Granite offers excellent thermal stability, vibration damping, and wear resistance, ensuring long-term dimensional accuracy.
The 40 × 40 mm square cross section and 600 mm length make this guide bar ideal for linear guidance, air bearing setups, optical alignment, and inspection fixtures. All working surfaces are precision ground to provide flat, straight, and square reference faces.
