Product Introduction

Spring-loaded ball plungers are precision mechanical components used for positioning, locking, and limiting motion. They consist of three core parts:

• ●Plunger Body: Cylindrical housing with mounting threads (or press-fit design).

• ●Spring: Internal compression spring providing constant thrust.

• ●Ball: Precision steel bearing ball protruding from the body, serving as the contact/positioning point.

Working Principle: The spring forces the ball outward. When external pressure is applied (e.g., against an edge or into a detent hole), the ball retracts into the body while compressing the spring. Once pressure is released or aligned with a hole, the spring extends the ball to achieve positioning, locking, or tactile resistance.

Key Features

• Rapid & Repeatable Positioning: Enables quick, accurate alignment of parts (e.g., panels, covers, fixtures).

• Adjustable Locking/Resistance: Spring tension provides customizable holding force to prevent unintended movement.

• Shock Absorption: Ball compression cushions impacts, protecting components from damage.

• Tactile/Audible Feedback: Distinct "click" and tactile response during engagement/disengagement.

• Easy Integration: Threaded (metric/imperial) or press-fit installation options.

• Compact & Reliable: Space-efficient design with long service life under proper conditions.

• Material Versatility: Stainless steel (corrosion-resistant), carbon steel (cost-effective), or engineering plastics (non-conductive/non-magnetic).

Summary
Though small, spring-loaded ball plungers are vital for micro-positioning and temporary locking in modern mechanics. Their compact size, reliability, and tactile feedback make them ideal for preventing slippage, enabling quick alignment, and enhancing user interaction. Selecting the correct specifications (thread, ball size, spring force, material) ensures optimal performance.
