Product Description
Threaded Ball Rollers
●Product Overview
A Spring-Less Ball Plunger (Threaded) is an innovative mechanical positioning component designed to replace traditional spring-loaded ball plungers. It eliminates the internal, fatigue-prone coil spring by employing a novel mechanical mechanism (e.g., utilizing precision balls, ramps, or special elastomers) to achieve the positioning and damping function. This design fundamentally solves common issues associated with traditional plungers, such as performance instability and short service life caused by spring failure. It delivers a more reliable, longer-lasting, and consistent tactile feedback experience. It is widely used in equipment and products requiring precise positioning, frequent actuation, or demanding environmental conditions.
●Key Features
Precise Positioning & Tactile Feedback:
Provides a clear, definitive "click" or detent feel during the movement of a device or component, ensuring it accurately stops at pre-set positions.
Offers positive tactile feedback to the user, enhancing the overall quality and user experience of the product.
The core advantage is the removal of the weakest link in traditional plungers—the metal spring—thereby preventing failure due to spring fatigue, fracture, or plastic deformation.
Significantly outperforms traditional ball plungers in lifespan, making it ideal for high-cycle applications.
Thanks to its stable internal mechanism, the positioning force (the "holding" strength) and tactile feel remain remarkably consistent throughout its service life, with no degradation over time.
The spring-less design makes it less sensitive to vibration and shock, ensuring more stable performance.
Excellent resistance to dust and contamination. The absence of spring gaps prevents the accumulation of debris, avoiding potential seizing issues.
Certain models, made from special materials, offer properties like corrosion resistance and high-temperature tolerance.
Some high-end spring-less plungers feature an adjustable torque function. The positioning force can be finely tuned within a range by rotating a setscrew at the rear, allowing for precise adaptation to various application requirements.
