Micrometer LIMIT MMB 150–175 mm — LIMIT MMB 150-175

The LIMIT MMB 150–175 mm external micrometer is a mechanical measuring instrument designed for precise outside diameter and thickness measurements in the 150–175 mm range. It features a calibrated spindle and thimble that enable fine adjustments and clear scale reading, making it suitable for workshop measurement, inspection and quality-control tasks where consistent, repeatable results are required.

Advantages

The micrometer offers accurate incremental measurement across a wide span of 150–175 mm with a fine-adjustment thimble for controlled spindle travel. Its clear engraved scale allows straightforward reading without electronic components, ensuring reliable operation in environments where simple, durable tools are preferred. The mechanical construction provides long-term stability and resistance to common workshop conditions while requiring only routine maintenance.

Suitable for

• Measuring outside diameters of cylindrical parts in machining and turning operations
• Quality-control inspection of finished components in production
• Workshop and toolroom dimensional checks where precise manual measurement is needed

Key specifications

• Measuring range: 150–175 mm
• Type: external micrometer for outside diameter measurements
• Scale: calibrated spindle and thimble with engraved graduations for fine adjustment
• Construction: mechanical, durable frame suitable for workshop use
• Resolution: fine incremental adjustment (refer to instrument thimble graduations)

How to use

Position the micrometer anvils around the workpiece at the intended measuring point and rotate the thimble until the spindle contacts the surface with light, consistent pressure. Use any integrated ratchet or friction stop to avoid over-tightening and obtain a repeatable contact force. Read the measurement by combining the spindle scale and thimble graduations according to the instrument's engraved scale. After measurement, retract the spindle to remove the workpiece and store the micrometer in a protective case to prevent damage and contamination.

Usage recommendations

Before use, ensure measuring faces are clean and free of chips or burrs. Calibrate or verify zero reference periodically using traceable standards and avoid exposing the micrometer to extreme temperature changes during measurement to maintain accuracy.
