 TAPERED INDEX PLUNGERS, Rotary Cam, Standard Mount
 
FEATURES: Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15° taper on the plunger tip with a mating taper on the bushing. The taper makes alignment easier and also eliminates any binding during retraction (also available with a straight plunger, for slightly greater positional accuracy). 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:
• 1/2"
• 3/4"
• 1"
 
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.
 
MATERIAL: Plunger, body , and cam > 1144 steel, heat treated. Center shaft > 11L44 steel. Spring > Music wire. Ball knob > Black phenolic plastic with molded-in brass insert.

 TAPERED INDEX PLUNGERS, Rotary Cam, Flange Mount
 
FEATURES: Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15° taper on the plunger tip with a mating taper on the bushing. The taper makes alignment easier and also eliminates any binding during retraction (also available with a straight plunger, for slightly greater positional accuracy). The rotary-cam version completely retracts when the handle is rotated 180°. Cam surfaces are hardened steel. The flange-mount configuration shown here has a precision ground body with a flange used for orientation by fastening with two socket-head cap screws (also available with a slightly oversize unground body to allow custom grinding to size). Flange mounting is designed for installations where a cross hole for a set screw is not practical. Order plunger and bushing separately.
 
SIZES: Choice of two plunger diameters:
• 1/2"
• 3/4"
 
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. Center shaft > 11L44 steel. Spring > Music wire. Ball knob > Black phenolic plastic with molded-in brass insert.

 TAPERED INDEX PLUNGERS, Blank Machinable End
 
FEATURES: Index plungers are precision, heavy-duty assemblies with a retractable spring-loaded plunger and a matching locating bushing. Tapered Index Plungers feature a 15° taper on the plunger tip with a mating taper on the bushing. The taper makes alignment easier and also eliminates any binding during retraction (also available with a straight plunger, for slightly greater positional accuracy). The version shown here has a blank machinable end for easy adaptation to various actuating devices, including automated setups. Precision ground body (also available with a slightly oversize unground body to allow custom grinding to size). Order plunger and bushing separately.

 STRAIGHT INDEX PLUNGERS, Rotary Cam, Standard Mount
 
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).
