Micrometer Slide 2 Inch Travel (0.0001) with Post

Description

The Gaertner Scientific M301A micrometer slide has two inches of travel. The carriage is threaded to accept the standard Gaertner measuring microscopes and telemicroscopes. The carriage ways are precision hand-scraped, and the leadscrew is hand-lapped to the nut. There is a special cam that tilts the nut as the carriage is positioned, thereby correcting any residual errors in the pitch of the lead screw.

There is a two inch scale to indicate the coarse position of the carriage, and a precision graduated drum to indicate the fine position directly to 0.0005 inches, and to 0.0001 inches via the vernier. A 19mm diameter post, 6 inches in length is permanently attached to the slide.

The slide is in excellent condition, and has been cleaned and relubricated.
