Features of GN615.3 Threaded Ball Plungers

GN615 Threaded Ball Plungers Title:

Socket Ball Spring Plunger SUS304 GN615.3 Ball Screw Plunger. The GN615.3 Threaded Ball Plunger series represents a pinnacle in precision indexing and locating components. Engineered with a resilient stainless steel body, this socket ball spring plunger delivers consistent tactile feedback and mechanical reliability. Procurement teams and engineering departments rely on the SUS304 GN615.3 ball screw plunger to secure positioning across complex mechanical assemblies, ensuring long-term stability even under continuous dynamic loads.

GN615.3 Ball Plunger Screw Introduction:

GN615.3 Spring Plungers are threaded ball spring plungers, Body can be made from carbon steel with black oxide finish or stainless steel. Designed to endure high-frequency vibrations and harsh outdoor environments, the corrosion-resistant SUS304 stainless steel option ensures reliable operation without structural degradation. To support rapid integration into your specific equipment designs, we provide comprehensive 2D and 3D CAD models along with detailed technical drawings. This engineering support allows design teams to efficiently incorporate our components into their blueprints, reducing development time. Our manufacturing process supports extensive OEM and ODM customization. Whether your project requires non-standard dimensions, specialized anti-corrosion coatings, or differentiated spring loads, our flexible production lines can adapt to meet those exact operational demands.

Thread Size: Metric Thread (M3/M4/M6 or Customize special sizes). We accommodate varied dimensional requirements for specialized machinery, ensuring a precise fit across different structural frameworks.

Ball Material: Steel (surface hardening treatment) or stainless steel (corrosion-resistant). The hardened steel sphere offers a smooth, low-friction glide, while the stainless variant withstands aggressive chemical exposure.

Surface treatment: Provide nickel plating and Plaining. These finishes not only enhance the metallic luster but also create a formidable barrier against oxidation in damp settings.

Thread locking: Nylon Patching or Polyamide Blue Coating, etc. This optional accessory integration acts as an all-in-one fastening solution, preventing loosening caused by structural vibration.

Spring Type: We offer multiple tension profiles to match exact mechanical requirements:

Standard Spring-GN615.3-K K:Steel, standard spring load. Ideal for general-purpose detent mechanisms requiring moderate tactile resistance.

Hevay-duty Spring-GN615.3-KS KS:Steel, high spring load. Engineered for heavy machinery where strong locking forces are critical to operational safety.

Supplement:

KN:Stainless Steel, standard spring load    KSN:Stainless Steel, high spring load. These stainless options are perfect for corrosive environments.

Installation Method: Thread into the installation hole. The internal hexagon socket allows for quick, secure tightening using standard tools, minimizing assembly time.

Application:

Automation equipment field, industrial anti loosening field, etc. The GN615.3 threaded ball plunger is widely adopted across multiple demanding sectors due to its precise mechanical engagement and reliable retention capabilities. In the automation equipment field, these plungers act as essential indexing elements within control levers, ensuring accurate positioning during rapid machine cycles. The distinct click and firm hold provide operators with clear tactile confirmation of engagement. Furthermore, they excel in the industrial anti-loosening field, where continuous vibration threatens structural integrity. Beyond these core areas, our stainless steel variants are extensively utilized in food processing machinery and chemical manufacturing equipment. The SUS304 body resists acidic and alkaline washdowns, maintaining strict hygiene standards without rusting or degrading. Outdoor facilities and recreational equipment also benefit from their weather-resistant properties, functioning smoothly despite exposure to rain, dust, and fluctuating temperatures. Whether integrated into complex ejection mechanisms or simple snap-on indexing fixtures, these components deliver consistent force. We provide dedicated mounting blocks and accessories to ensure complete system compatibility across all these diverse applications.
