Master Cylindrical Square (Granite)
TAC Rockford Precision Granite Master Cylinders are the standard for verifying the perpendicularity, straightness, and runout of critical machine axes on high-precision machine tools and CMMs. Manufactured from select, high-density black granite, these cylinders offer unmatched dimensional stability and thermal inertness, making them essential for the most demanding metrology applications.
Standard sizes range from 200mm (7.87in) to 800mm (31.5") in height. Custom diameters, heights, and other special versions available upon request - contact our engineering team for specialized configurations.

Key Features & Benefits
Superior Accuracy: Laboratory Grade accuracy for the highest confidence in your measurements.
Thermal Stability: Granite's extremely low coefficient of thermal expansion minimizes dimensional changes due to temperature fluctuations, ensuring reliable readings in a controlled environment.
Exceptional Durability: The hard, dense granite resists wear, is non-magnetic, and is corrosion-proof, guaranteeing a long service life with minimal maintenance.
Precision Finish: Both the diameter and the ends are precision-lapped to achieve perfect parallelism, perpendicularity, and cylindricity, making them ideal for verifying the straightness and squareness of machine tool columns, calibrating the Z-axis of Coordinate Measuring Machines (CMMs) and checking the runout of rotary tables and spindles.
Traceability: Each cylinder is supplied with a calibration certificate to meet your strictest quality assurance requirements.
Applications:
- Coordinate Measuring Machines (CMMs)
- Machine Tool Calibration (Vertical Machining Centers)
- Precision Gauging and Layout
- Optical Inspection Systems
- Quality Control and Metrology Labs
