Mitutoyo 148-362 Mechanical Micrometer Head

Product Description

The MITUTOYO 148-362 is a mechanical micrometer head designed for precision linear measurement in tooling, fixturing, and inspection applications. It features a rotating flat spindle with a 6.35mm (0.25 inch) diameter and a spindle length of 15.50mm (0.6102 inches), providing a measurement range of 0.5 inches with an accuracy of 0.0001 inches. The thimble diameter measures 1.14 inches and is finished in chrome-plating for corrosion resistance and durability. The measuring face is SKS3 tool steel, suited for demanding contact-measurement tasks. Licensed metrology technicians, machining professionals, and quality control inspectors are the primary users of this component.

The MITUTOYO 148-362 is suited for use in precision machining environments, inspection fixtures, and automated gauging setups where repeatable linear positioning is required. Its short thimble design with selectable thimble diameter options makes it a practical fit for space-constrained fixture assemblies. The 0.375 inch diameter stem, 9.50mm (0.374 inches) in length, allows straightforward mounting in standard micrometer head bores common in laboratory and production-floor tooling.

Key Features

• 0.0001 inch accuracy for high-precision measurement tasks
• Rotating flat spindle, 6.35mm diameter x 15.50mm (0.6102 inches) long
• 1.14 inch thimble diameter in a short thimble configuration
• SKS3 tool steel measuring face for wear resistance
• Chrome-plated finish for corrosion protection
• 0.375 inch diameter x 9.50mm stem for standard fixture mounting

Compatibility

Designed as an OEM-style precision micrometer head for use in standard fixture, tooling, and gauging setups that accept a 0.375 inch diameter stem mount.

Installation Notes

Installation is typically performed by metrology technicians or machining professionals integrating the head into a fixture or gauging assembly. Secure the stem in the mounting bore to the fixture manufacturer's specified clamping method before applying any measurement load. Avoid over-tightening the stem clamp, as this can induce spindle misalignment and affect accuracy. Verify zero calibration after mounting and before taking measurements.
