Mitutoyo 952623 Bore Gage Extension Rod 2-12 in

Product Description

The MITUTOYO 952623 is a bore gage extension rod designed to extend the reach of compatible bore gages within a 2 to 12 inch measurement range. Measuring 5-29/32 inches in length, this single-piece rod integrates into existing bore gage setups to accommodate deeper bore measurements that fall outside the standard gage reach. It is a direct replacement or supplemental accessory component intended for use by machinists, metrology technicians, and precision measurement professionals working in manufacturing, inspection, and tooling environments.

This extension rod is suited for applications where internal bore diameter measurement requires additional depth access. Typical use cases include quality control inspection of deep bores in machined components, engine cylinders, hydraulic housings, and similar precision-machined parts. It is used in conjunction with bore gages configured for the 2 to 12 inch range, making it applicable across a range of industrial and production measurement tasks.

Key Features

• Extends bore gage reach for measurements in the 2 to 12 inch range
• 5-29/32 inch rod length provides added depth access
• Single-piece construction for reliable, consistent integration
• Designed as an accessory replacement component for compatible bore gage systems

Compatibility

Designed for use with bore gages configured for the 2 to 12 inch (50 to 300 mm) measurement range.

Installation Notes

Installation is typically performed by a machinist or metrology technician familiar with precision measurement equipment. Before attaching or removing extension rods, ensure the bore gage is not under load and is handled on a stable, clean surface to prevent damage to measuring surfaces or threads. Follow the bore gage manufacturer documentation for proper rod attachment procedures and torque-free hand-tightening guidelines where applicable. Calibration verification is recommended after any configuration change to confirm measurement accuracy.
