Ball Plunger Spring Loaded Function:
Press-fit construction ensures secure mounting, minimizing vibration-induced displacement;
Precision ball design guarantees stable positioning and repeatability;
Standard models for general loads; heavy-duty versions with reinforced springs available;
Customization Services
Material Combinations: Flexible selection of body, ball, and spring materials;
Dimensions & Parameters: Adjustable body diameter, ball size, and spring force to meet non-standard requirements
Industrial Equipment-Positioning in automated fixtures、Food processing systems、locking components for medical equipment,etc.

Advatage of Spring Ball Plunger :
No welding/no threading design: using Press Fit cold connection technology, directly pressing into the pre machined hole position without welding or threading.
By providing high clamping force through elastic deformation of the ball, the connection stability is maintained even under vibration or impact.
