Ball and Spring Index Plungers

Ball and Spring Index Plungers are used wherever components are to be guided, positioned or guided and are usually used permanently as a detent element. A resilient thrust piece consists of a press sleeve or threaded screw, a spring which exerts pressure on the element to be guided, and a ball or bolt as a sliding and guiding element. For the assembly of the resilient thrust piece it is necessary to plan a suitable bore or groove for the mounting. This positioning is permanently secured by pressing or screwing it onto the workpiece.

BÄCKER has the spring-loaded thrust pieces in numerous material variants in its product range. The threaded body or the press-in bush is available in steel or stainless steel, depending on the design. With the screw versions, the pressure pieces are attached in the desired position via a hexagon or slot or alternatively pressed in via a bush. The guide element or bolt is available in steel, stainless steel or Delrin/POM and is designed for different applications in versions with normal or reinforced compression spring.   

Application scenarios for spring-loaded thrust pieces are in industrial use as well as in private use. In order to ensure a defined position in the interaction of two assembly parts in relation to each other, the thrust piece is attached to one element, while the counterpart has a groove or bore into which the element can engage. Once the element is engaged, the pressure pads hold the component securely in the desired position even when subjected to vibrations. As soon as the latching is actively released, the spring-loaded pusher releases the assembly part and the ball or bolt is pressed into the housing.
