FEATURES: Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. 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). The rotary-cam version completely retracts when the handle is rotated 180°. Cam surfaces are hardened steel. The standard-mount configuration shown here has a precision ground body with a whistle notch for orientation with a setscrew (also available with a slightly oversize unground body to allow custom grinding to size). Order plunger and bushing separately.
SIZES: Choice of three plunger diameters — see Dimensions page for part numbers:
INSTALLATION: Index plungers are manufactured with precision working tolerances and are designed for very light interference-fit installations to avoid binding of the mechanism. Setscrews with nylon tip inserts are recommended. Setscrews should firmly contact the whistle notch, but not exert significant force.
