Description
Product Overview
The VCN410-B Brass Press Fit Ball Plunger is a precision-engineered positioning component, purpose-built for industrial manufacturers, automation equipment builders, and precision engineering firms requiring reliable, space-saving locking and alignment solutions. As a flagship brass press fit ball plunger, this component eliminates the need for threaded mounting holes, featuring a compact, lightweight design that streamlines assembly processes without compromising mechanical performance. Crafted with a high-strength brass body, SUS440C stainless steel ball, and SUS304 stainless steel spring, it delivers consistent performance in both light-duty precision tasks and heavy-load industrial operations, with dual spring load configurations to match diverse application needs.
Key Features & Industrial Performance Advantages
High-Strength Brass Body for Superior Corrosion Resistance
Machined from premium brass with tight ±0.01mm tolerances, the body of the VCN410-B Brass Press Fit Ball Plunger offers exceptional corrosion resistance and structural stability, making it suitable for demanding industrial environments with exposure to oils, mild chemicals, and fluctuating temperatures.
Ultra-Hard SUS440C Ball for Long-Lasting Wear Resistance
The integrated ball is forged from SUS440C stainless steel with a hardness of 50HRC (58-62HRC for high-precision variants) and a surface finish of Ra≤0.4μm, ensuring smooth retraction, minimal wear, and extended service life even in high-frequency operation cycles.
Dual Spring Load Options for Versatile Industrial Needs
This spring loaded brass ball plunger is available in both Light Load and Heavy Load variants. Light Load models deliver gentle, tactile feedback for precision adjustments, while Heavy Load options provide robust locking force for high-vibration machinery, eliminating the risk of unintended displacement.
Tool-Free Press Fit Installation for Reduced Assembly Time
The press-fit design enables fast, tool-free installation, eliminating the need for additional fasteners or threaded hole machining. This cuts assembly time by up to 60% for production lines, reducing labor costs and minimizing downtime for equipment maintenance.
