Vlier SSB50AP Threaded Ball Plunger 8-32 Stainless Steel

Product Description

The VLIER SSB50AP is a threaded ball plunger designed for controlled end-force applications where space and weight are critical constraints. It features an 8-32 thread size, a stainless steel body, and a stainless steel ball measuring 0.094 inches in diameter. The body length is 0.344 inches, and the maximum ball reach is 0.025 inches. Initial end force is 0.5 pounds and final end force is 1.25 pounds. A locking element is included. This is among the smallest and lightest spring-loaded positioning devices available, suited for precision mechanical assemblies requiring repeatable, low-force detent or positioning action.

The SSB50AP is used in applications requiring controlled, light-duty end force in tight spaces. Typical installations include precision instruments, jigs, fixtures, tooling, and light mechanical assemblies where consistent ball engagement force and minimal footprint are required. The 8-32 threaded body allows direct installation into tapped holes in standard tooling plate or machined components. The stainless steel construction makes it suitable for environments where corrosion resistance is a consideration.

Key Features

• 8-32 thread size for direct installation into tapped holes
• Stainless steel body and ball for corrosion resistance
• 0.094 inch ball diameter with 0.025 inch maximum ball reach
• 0.5 pound initial end force and 1.25 pound final end force for controlled detent action
• Locking element included to secure position after installation
• Compact, lightweight design suited for space-constrained assemblies

Compatibility

Designed as an OEM-style threaded ball plunger for use in any application accepting an 8-32 threaded spring-loaded positioning device.

Installation Notes

Installation requires a properly tapped 8-32 hole in the mating component. Use an appropriate driver to thread the plunger body into place and engage the locking element to secure it against loosening from vibration. Ensure the mating surface and ball engagement geometry are verified before final assembly. Disassembly or adjustment should be performed with the assembly de-energized or fully secured.
