Description

Now also available in metric sizes! Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing (order separately). Straight Index Plungers have an entirely cylindrical plunger with a slight radius at the tip, used together with a straight bushing. A straight plunger provides slightly greater positional accuracy (also available with a tapered plunger, for easier alignment). Rotary-cam action completely retracts the plunger when the handle is rotated 180°. Cam surfaces are hardened steel. Made in USA. The flange-mount configuration shown here provides orientation by fastening the flange with two socket-head cap screws. Flange mounting is designed for installations where a cross hole for a whistle-notch set screw is not practical. This configuration is available in two sizes, with the following inch and metric plunger diameters: 1/2″ and 12mm 3/4″ and 20mm Index Plungers and their matching bushings feature a precision-ground body diameter, but are also available with a slightly oversize unground OD to allow custom grinding to size.
