Precision Parallel Gauging Pin for Macro-Style Chuck Centering & Alignment

The PA-21008V-TR is a high-precision parallel gauging pin (control ruler) designed for use with Macro-style chucks and automation systems. It is an essential tool for setting angular positions, centering chucks, and verifying alignment during machine setup.

Unlike traditional designs that rely on a center reference hole, the PA-21008V-TR utilizes precision-ground long-edge reference surfaces to provide accurate alignment. This design approach delivers the same functional accuracy while offering a more cost-effective solution for users seeking reliable setup tools.

Manufactured from hardened stainless steel (HRC 48–52) , this gauging pin offers exceptional wear resistance and dimensional stability. The reference surfaces are precision ground to achieve a parallelism tolerance of ±0.002mm, ensuring consistent and repeatable alignment results.

Key Benefits:

• Cost-Effective Alternative: Provides reliable alignment functionality without the premium cost associated with center-hole designs.

• Long-Edge Reference: Precision-ground long-edge surfaces deliver accurate angular positioning and centering.

• High Precision: ±0.002mm parallelism tolerance ensures repeatable setup accuracy.

• Durable Construction: Hardened stainless steel withstands frequent use in shop floor environments.

• Easy Integration: Designed for use with Macro-style chucks and clamping systems.

Typical Applications:

• Setting angular positions on Macro-style chucks

• Centering chucks during machine setup

• Verifying alignment of automation workholding systems

• Tool presetting and calibration routines

Compatibility: The PA-21008V-TR is designed for use with Macro-style chucks and clamping systems utilizing industry-standard interfaces. The long-edge reference design ensures compatibility with systems requiring precise angular positioning.

Note: This parallel gauging pin provides accurate alignment via its precision-ground long-edge surfaces. For applications requiring a center reference hole, please contact our technical support to discuss alternative options.
