Mitutoyo 301655 Drop Indicator Replacement Rod 1 in

Product Description

The MITUTOYO 301655 is a replacement rod designed for use with Mitutoyo drop indicators. The rod measures 1 inch in diameter and serves as a direct OEM-style replacement component when the original rod is worn, damaged, or lost. Drop indicator rods are precision measurement parts that must meet tight dimensional tolerances to ensure accurate gauge readings. This replacement is sold individually and is intended for installation by calibration technicians, machinists, or metrology professionals who service and maintain precision measuring instruments in shop or lab environments.

This replacement rod is suited for metrology and quality control environments where drop indicators are used to measure surface variation, runout, or part alignment. It fits into maintenance and rebuild workflows for Mitutoyo drop indicator models that accept a 1-inch diameter rod. Shops that maintain their own measurement equipment inventory typically stock replacement rods to minimize downtime during calibration cycles or after field damage.

Key Features

• 1-inch diameter rod matched to Mitutoyo drop indicator specifications
• OEM-style replacement for worn or damaged drop indicator rods
• Sold individually for single-unit service needs
• Precision-dimensioned to maintain gauge accuracy after replacement

Compatibility

Designed as an OEM-style replacement rod for Mitutoyo drop indicators that require a 1-inch diameter rod. Verify compatibility with the specific drop indicator model before ordering, as rod dimensions vary across indicator families.

Installation Notes

Installation should be performed by a qualified calibration technician or machinist familiar with Mitutoyo drop indicator disassembly procedures. Remove the indicator from service and ensure no load is placed on the mechanism before replacing the rod. Handle precision components with clean, dry hands or lint-free gloves to avoid contamination that could affect measurement performance. After installation, verify gauge zero and repeatability before returning the instrument to service.
