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