It is a product that sets the internal pressure of the beads & pins and moves up and down. Suitable for mechanical devices, fixtures, molds, automated machinery ... etc.

Although it can be installed with a screwdriver or an Allen wrench, most experts recommend using a dedicated spring plunger wrench especially for novices. Use of the wrong tool to run the risk of over-compressed springs and damage. As any technician knows, you should always work with the right tools. The biggest danger during installation is that the plunger spring uses too much torque. Although they are like bolts or screws, their bodies are hollow, and there is a limit to the power they can tolerate. If in doubt, ask the manufacturer with the highest mounting torque

The spring ball plunger should have accurate end pressure. By minimizing the thickness of the bushing pin head and using the longest quality spring as much as possible, it can reduce the fatigue of the spring and increase its service life. The height of the ball head of each plunger protruding from the plunger body must be uniform. Precise processing control and strict inspection procedures must ensure that the size difference between the protruding height of each plug ball head does not exceed 0.1mm. Some specifications must not exceed 0.05mm

Widely used in some medical equipment, lubrication equipment, pneumatic tools and other products. Engineers often use it in mold, fixture, assembly and other tasks. With the help of a certain pressure spring, the ball is moved to make the equipment run smoothly.
