How the 50150 Bore Gauge Works in Bore Measurement
The 50150 uses a twin‑anvil measuring system that self‑centers inside the bore through a slight radial adjustment. When combined with the 2109A10 dial gauge, the revolution indicator shows both diameter deviation and run‑out in a single revolution read‑out.
Because the anvils are carbide tipped, they resist wear even when inspecting rough‑cast or lightly hardened surfaces. The hardened steel body maintains dimensional stability across temperature swings on the shop floor.
Mounting and Setup for 2109A10 Dial Integration
Installing the 2109A10 onto the 50150 spindle is straightforward, and a secure attachment minimizes backlash during inspection. Proper setup ensures that the revolution indicator correctly tracks bore eccentricity and micro‑movements.
Following a few setup best practices reduces repeatability errors and makes each bore reading more consistent across shift changes and operators.
Recommended Setup Steps
- Clean the spindle and anvil seating surfaces to remove chips and oil.
- Thread the 2109A10 onto the 50150 spindle until hand tight, then gently lock.
- Set the revolution indicator zero position at a known reference diameter.
- Verify that the active measuring anvils move freely without sticking.
Dial Indicator Performance and Readability Features
The 2109A10 dial gauge on the 50150 delivers clear, high‑contrast readings even in mixed lighting. The large revolution indicator dial simplifies monitoring bore run‑out without repositioning the part.
With a 10 mm stroke and fine revolution marking, the gauge supports both quick pass/fail checks and finer trending analysis for process drift on internal diameters.
Accuracy, Calibration, and Maintenance Best Practices
Maintaining the accuracy of the Mitutoyo Bore Gauge 50150 with the 2109A10 dial gauge requires regular calibration and careful handling. Proper storage and cleaning directly impact long‑term repeatability on the shop floor.
Establishing a simple maintenance routine helps you catch wear early and keep measurement confidence high across multiple inspection stations.
Practical Tips for Production Floor Use
Optimizing the Mitutoyo Bore Gauge 50150 with the 2109A10 dial gauge on the shop floor reduces inspection time and supports consistent bore quality.
- Always check spindle free motion before each measurement cycle.
- Use the revolution indicator to detect out‑of‑round conditions without extra accessories.
- Store the assembly in a padded case to protect the anvil tips and dial housing.
- Schedule regular calibration checks based on inspection frequency and part tolerances.
FAQ
Reader questions
What measuring range does the Mitutoyo Bore Gauge 50150 provide with the 2109A10?
The 50150 active measuring range is 60–160 mm, and the 2109A10 dial indicator accommodates this range with its 10 mm stroke and revolution indicator.
Can the 2109A10 dial gauge be replaced if worn or damaged?
Yes, the 2109A10 dial module is designed for field replacement, and a new unit can be refitted to the 50150 spindle using the same standard mounting procedure.
Is a calibration certificate included when ordering the 50150 with 2109A10?
Many suppliers include a basic calibration certificate, but an extended certificate or NIST traceable options are available for regulated environments upon request.
How should I clean the carbide anvils of the 50150 after use?
Wipe the carbide anvils with a clean, soft cloth after each use, and inspect for chips or cracks; avoid using aggressive solvents that could affect the anvils’ finish or dimensions.
