Part Number
Configured Part Number is shown.
♢ The spring plunger is also known as the positioning column, ball screw, spring screw, etc. It is a product involving vertical stroke, in which the front pin is pressed till the pin sinks into the body and then the front pin can be ejected through the built-in spring. It can be used in mold release, workpiece lifting and positioning, etc., which can be widely applied in medium and low-precision mechanical devices, fixtures, molds, automation machines, etc.

Frequently asked question (FAQ)
- Question: What role does a spring plunger play?
- Answer: By controlling the screw-in depth for threads, it enables the internal pin to set the preload and perform up and down stroke movement. It is suitable for mechanical devices, fixtures, molds, automated machinery, etc.
- Question: What is the meaning of max load and min load?
- Answer: It refers to the load of the product. The min load represents the initial load value, and the max load represents the load value at the maximum press-in stroke.
- Question: What is the difference between a ball plunger and a spring plunger?
- Answer: A ball plunger is headed with a steel ball and its stroke is the displacement of the ball. A spring plunger has a pin-shaped front section and the displacement stroke of the pin is used for such purposes as temporary positioning, mold demoulding and workpiece lifting.
