GN815 Ball Head Plunger Introduction:
GN815 is a spring plunger with external threads and lockable function, which is positioned and pushed through steel balls. It has the characteristics of corrosion resistance, high precision, and environmental protection. Its standard parts are made of rust proof stainless steel, suitable for scenarios that require frequent adjustment or precise positioning;
Core structure composition
Spring plunger ball is a composite fastener mainly composed of three parts:
Spring (usually cylindrical spiral spring, providing continuous elasticity, commonly made of 65Mn, heat-treated process);
Steel ball (embedded in the front end of the spring as a positioning or pushing component, mostly made of stainless steel or carbon steel, with a hardened surface to enhance wear resistance);
With ball "means that there is a steel ball at the top of the screw, which is positioned and stopped by the pressure of the spring.
Material: The shell is made of stainless steel AISI 303, which has good corrosion resistance and mechanical properties; The steel ball material is hardened stainless steel AISI 420C, with high hardness and good wear resistance; The spring is also made of stainless steel material, ensuring its elasticity and corrosion resistance;
Shell/tube body (cylindrical structure with external threads, with a groove for storing springs inside, one end open for steel balls to extend, and the other end can be locked by means of a straight groove, an inner hexagon, etc.);
Size specifications: There are multiple sizes to choose from, such as M4, M5, M6, M8, M10, M12, etc.
Spring load: GN815 bead screws of different sizes have different spring loads;

Applications：
Mold industry: used for positioning mold templates and sliders to ensure accurate positioning of parts during stamping or injection molding processes;
Assembly operation: Fix small parts (such as screws and nuts) in mechanical assembly to prevent loosening;
Automation equipment: used to push or position small components (such as workpieces on conveyor belts, end effectors of robot arms);
Furniture and home appliances: such as the lifting and positioning of office chairs, the opening and closing limits of microwave oven doors;
Functional purpose:
The core function of the bead screw is to achieve "positioning" and "pushing" through the elastic force of the spring:
Accurate positioning:
The steel ball is pressed against the fixed component under the action of the spring, preventing it from shifting (such as fixing the position of the template in the mold or fixing the direction of the parts during assembly);
Adjustable Push: By rotating the shell and compressing or extending the spring, the steel ball can be extended or retracted to achieve fine adjustment or ejection of the component;
