    Straight Index Plungers (Rotary Cam, Flange Mount)

    Straight Index Plungers (Rotary Cam, Flange Mount)

    Spring-Loaded Devices

    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 the 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.

    Installation

    Index plungers are manufactured with precision working tolerances and are designed for very light interference-fit installations to avoid binding of the mechanism.

    Material

    Plunger, body, and cam > 1144 steel, heat treated Rc 50-55. Center shaft > 11L44 steel. Spring > Music wire. Ball knob > Black phenolic plastic with molded-in brass insert. Bushing > 1144 steel, heat treated. DFARS and RoHS compliant.
