Vlier SSB50 Threaded Ball Plunger 8-36 Stainless Steel

Product Description

The VLIER SSB50 is a threaded ball plunger designed for controlled end-force applications where a small, lightweight spring-loaded device is required. The body and ball are both constructed from stainless steel, offering corrosion resistance in demanding environments. The SSB50 features an 8-36 thread size, a ball diameter of 0.094 inches, and a body length of 0.344 inches. Initial end force is 0.5 pounds, with a final end force of 1.25 pounds. Maximum ball reach is 0.025 inches. This part is installed by machinists, toolmakers, and mechanical assembly technicians in precision positioning and indexing applications.

The SSB50 is suited for applications requiring repeatable, low-force ball detent action in a compact envelope. Its small form factor makes it appropriate for light-duty indexing, positioning, and detent functions in assemblies where space is constrained. The stainless steel construction supports use in environments where mild corrosion resistance is needed. This plunger is threaded directly into a tapped hole in the host component, making installation straightforward for tooling and fixture work.

Key Features

• 8-36 threaded body for direct installation into tapped holes
• Stainless steel body and ball for corrosion resistance
• 0.094 inches ball diameter for precise, low-profile detent engagement
• Initial end force of 0.5 pounds and final end force of 1.25 pounds for controlled positioning
• Maximum ball reach of 0.025 inches for minimal protrusion
• Compact 0.344 inches body length - among the smallest and lightest spring-loaded devices in this class

Compatibility

Designed as a general-purpose threaded ball plunger for precision tooling, fixtures, and mechanical assemblies requiring controlled end-force detent action with an 8-36 thread size.

Installation Notes

Installation is performed by threading the SSB50 into a properly tapped 8-36 hole in the host component using appropriate hand tools. Ensure the mating hole is tapped to the correct thread specification and free of debris before installation. Do not overtighten, as this can damage the small-diameter threads or affect ball travel. Verify ball reach and end force meet the assembly requirement before final installation.
