Vlier SSB60N Threaded Ball Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSB60N is a threaded ball plunger designed for controlled end-force applications in mechanical assemblies. It features a 1/2-13 thread size, a stainless steel body, and a stainless steel ball measuring 0.281 inches in diameter. The maximum ball reach is 0.072 inches, with an initial end force of 6 pounds and a final end force of 12 pounds. This plunger incorporates a locking element to secure position after installation. Its compact, lightweight design makes it one of the smallest spring-loaded positioning devices available for precision indexing and detent applications.

The SSB60N is suited for use in jigs, fixtures, tooling, and light industrial assemblies where repeatable spring-loaded positioning is required. The stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, including food processing equipment, medical device tooling, and marine-adjacent applications. It is installed by machine operators, toolmakers, and mechanical assemblers working in manufacturing and industrial maintenance settings.

Key Features

• 1/2-13 thread size for standard tapped-hole installation
• Stainless steel body and ball for corrosion resistance
• Initial end force of 6 pounds and final end force of 12 pounds for controlled detent action
• Maximum ball reach of 0.072 inches for precise positioning travel
• Locking element included to secure the plunger in place after installation
• Compact, lightweight spring-loaded design suited for space-constrained assemblies

Compatibility

Designed as a direct-fit threaded ball plunger for applications requiring a 1/2-13 tapped hole and controlled end-force spring-loaded positioning.

Installation Notes

Install using a standard hex wrench or spanner into a tapped 1/2-13 hole. Ensure threads are clean and free of debris before installation. The locking element should be engaged after the plunger is positioned to prevent backing out under vibration or repeated cycling. Always de-energize or lock out any associated machinery before servicing or replacing spring-loaded positioning components.
