Mitutoyo 136290 Ball Contact Point Carbide 0.0787 in

Product Description

The MITUTOYO 136290 is a carbide ball contact point designed for use with dial test indicators. It features a 0.0787 inch (2.00 mm) ball diameter and a 1.2 inch contact point length, providing precise and repeatable contact for measurement applications. The carbide construction delivers hardness and wear resistance suited to high-cycle inspection environments. This contact point is installed by metrology technicians, machinists, and quality control personnel working with indicator-based measurement setups on manual or automated inspection fixtures.

This contact point is designed for indicator-based measurement tasks in precision machining, quality inspection, and dimensional verification environments. It is intended for use with Mitutoyo 513 Series Dial Test Indicators. Typical applications include runout checks, surface alignment, bore gauging setups, and fixture qualification in manufacturing or machine shop settings where consistent, low-force stylus contact is required.

Installation Notes

Contact points are typically replaced or swapped by qualified metrology or machine shop personnel. Before replacing the contact point, ensure the dial test indicator is removed from service and secured. Use the appropriate contact point wrench or driver to avoid damaging the indicator spindle threads. Avoid overtightening, as excessive force can affect indicator performance and thread integrity.
