When your automated setups, mold designs, or indexing fixtures require highly repeatable and durable positioning components, the SNSP000002 series stainless steel spring plungers by Sinoboltco provide the ideal industrial solution. Completely built from high-grade stainless steel (including the body, internal pin, and spring), these heavy-duty elements resist rust, chemicals, and mechanical wear in harsh factory environments.
This product line offers flexible configurations to suit specialized engineering demands. Designers can choose between light load and heavy load spring forces, as well as three distinct pin head shapes: Flat, Spherical, and Taper R. With pin diameters ranging from 2mm to 5mm (machined to precise h7 tolerances) and customizable stroke lengths, Sinoboltco ensures every positioning component delivers identical spring pressure and smooth stroke cycles. Every single batch undergoes thorough dimensional control and spring load cell verification to prevent field failures and minimize machine downtime.
Product Advantages
Complete Stainless Steel Integrity: The body, pin, and internal spring are all crafted from premium stainless steel, eliminating the risk of internal corrosion or spring jamming in humid or corrosive settings.
Dual Spring Load Options: Available in both Light Load and Heavy Load variants, allowing mechanical engineers to specify exact end-forces ranging from 0.49N up to 7.06N.
Precision h7 Pin Tolerances: Features tight Dh7 body sizing (2mm to 5mm diameters) for flawless, slip-fit alignment inside precision-reamed positioning holes.
Versatile Contact Faces: Flat, Spherical, and Taper R pin geometries adapt easily to different detent plates, sliding rails, and workpiece materials.
Industrial-Grade Cycle Life: Designed for millions of compression strokes without significant spring fatigue or force degradation.
