Mitutoyo 150-206 Micrometer Head

The Mitutoyo 150-206 is a mechanical micrometer head designed for precise linear measurement and positioning tasks. It offers a 0 to 1 inch range with a 0.001 inch resolution and 0.0001 inch accuracy. The steel spindle features a spherical tip and a 3/8 inch mounting hub diameter for fixture integration.

Installation and common issues

Mount the head using the 3/8 inch diameter hub and secure it with the included spanner and spindle lock nut. The ratchet thimble provides consistent measuring force during operation. The rotating spindle design requires clearance for axial movement; ensure the spherical contact point aligns correctly with the workpiece surface to avoid cosine errors.

Capacity and headroom

This head covers a maximum measurement of 1 inch from a zero starting point. The chrome-finished scale and 6.35 mm steel spindle deliver the stated accuracy within this range. Measurements beyond 1 inch exceed the calibrated capacity, and the mechanical resolution limit of 0.0001 inch defines the finest reliable reading. JIS B 7502 compliance confirms the manufacturing standard.

Questions about this item

How can I confirm the Mitutoyo 150-206 reads correctly after mounting it?

Zero the thimble with the spindle fully closed, then apply the ratchet stop to a calibrated gauge block; the sleeve should indicate the block size within the stated 0.0001 in accuracy.

What comes with the 150-206 and what must I source separately?

The head includes a spanner for the 3/8 in mounting hub and a spindle lock nut; a setting standard or gauge block for verification is not supplied.

Which version of the 150-206 suits a fixture needing a 6.35 mm steel spindle with spherical contact?

This model provides exactly that — a 6.35 mm steel spindle with spherical tip, ratchet thimble, spindle lock and chrome-finished inch graduations to 0.001 in.
