Starrett 52759 Dial Indicator Adapter Snug Sleeve

Product Description

The STARRETT 52759 is a snug sleeve adapter designed to connect dial indicators and indicator attachments to a 657X rod. It features two 0.25 inch diameter holes and is built for use with 196, 650, and 651 Series dial indicators, as well as the 657Y Indicator Attachment. This adapter allows technicians and machinists to extend the versatility of their existing indicator setups by providing a secure, snug-fit connection to the 657X rod system. It is a small but critical component in precision measurement assemblies used in machining, inspection, and alignment applications.

This adapter is used in precision metrology setups across machine shops, manufacturing facilities, and maintenance environments. It is typically installed when mounting a 196, 650, or 651 Series dial indicator or a 657Y Indicator Attachment onto a 657X rod as part of a magnetic base or indicator holder assembly. Technicians performing runout checks, surface alignment, or bore measurement will find this adapter essential for integrating compatible indicators into modular indicator arm systems.
