Product Description
Product Introduction
Threaded spring plungers are mechanical positioning components driven by internal springs to actuate a ball or plunger head. Featuring a metal threaded body, they screw directly into equipment bases. Their core function is to provide retractable spring pressure for workpiece positioning, indexing, or datum adjustment. Standard construction includes a threaded sleeve, spring, ball/plunger head, and locking mechanism .
Key Features
●Precision Positioning & Control
Preloaded springs ensure consistent contact pressure, achieving repeatable positioning accuracy (≤0.1mm error). Ideal for precision jigs and automation.
Extended-life springs reduce fatigue for enhanced durability.
●Versatile Operation Modes
Standard Type: Automatically rebounds after external force release.
Locking Type : Rotational mechanism holds plunger retracted for easy workpiece loading/unloading.
●Environmental Adaptability
Black oxide-coated steel withstands 250°C.
Compact designs with 7.1mm retraction suit space-limited applications.
●Vibration Resistance
Nylon thread locks prevent loosening under vibration.
