Spring Plungers Stainless Steel, Short Stroke (Part Numbers)

Product Overview
♢ This series is MISUMI economy series stainless steel spring plunger with coarse threads and mounted from the hexagon socket at the bottom. It is manufactured in China, so its price is reduced significantly, up to 93% less than other similar products.
♢ 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.
