The press-fit spring plunger, also known as a ball head plunger, is a load-bearing component made up of a casing, spring, and a ball. It is widely used in products like medical devices, lubrication systems, and pneumatic tools. The key features of this plunger include excellent rebound ability and strength, allowing it to withstand certain amounts of pressure and tension.

As a sealing element in mechanical transmission, the press-fit spring plunger plays a crucial role in supporting and securing. The plunger can bear pressure and tension, preventing parts from loosening or shifting. Through the pressing of the spring, the ball head plunger firmly holds adjacent components together, enhancing the overall stability.

Press-fit spring plungers are widely used in industries such as machinery manufacturing, automation, and automotive. They are also found in household equipment and furniture assembly. Engineers often use them in mold making, fixtures, and assembly processes.
