Description
The MITUTOYO 303611 is a replacement rod designed for use with Mitutoyo drop indicators. The rod measures 10mm in diameter and is intended to restore indicator function when the original rod is worn, damaged, or lost. Drop indicators rely on precise rod geometry to ensure accurate plunge-style measurements, and using an OEM replacement rod helps maintain calibration integrity. Installation is performed by metrology technicians, machinists, or quality control personnel working with dial-type measurement instruments.
This replacement rod is suited for shop floor, inspection, and toolroom environments where Mitutoyo drop indicators are in regular use. It is sold as a single-piece replacement part and is appropriate for maintenance of existing instruments rather than as a component in a new build. Verify the rod diameter and indicator model compatibility before ordering to ensure a correct fit.
Key Features
- OEM replacement rod maintains original indicator measurement accuracy
- 10mm rod diameter for precise fit in compatible Mitutoyo drop indicator housings
- Single-piece package quantity for individual instrument servicing
- Designed to restore drop indicator function after rod wear or damage
Compatibility
Designed as an OEM-style replacement rod for Mitutoyo drop indicators requiring a 10mm diameter rod. Confirm compatibility with your specific indicator model number before installation.
Installation Notes
Installation should be performed by a qualified metrology technician or machinist familiar with dial indicator servicing. Remove the indicator from service and ensure it is not under load before disassembling. Handle the replacement rod carefully to avoid surface damage that could affect measurement accuracy. Recalibrate or verify the indicator against a known reference standard after rod replacement.
