Vlier SSB52 Threaded Ball Plunger 10-32 Stainless Steel

Product Description

The VLIER SSB52 is a threaded ball plunger designed for controlled end-force applications where size and weight constraints are critical. Built with a stainless steel body and stainless steel ball, this spring-loaded device delivers consistent, repeatable positioning force in a compact form factor. The 10-32 thread makes it straightforward to install into tapped holes on assemblies, fixtures, and mechanisms. It produces an initial end force of 1.5 pounds and a final end force of 3 pounds, giving technicians a predictable force range for detent, indexing, and alignment tasks. The 0.094-inch ball diameter and 0.513-inch body length make this one of the smallest and lightest spring-loaded plungers available in this thread class.

The SSB52 is suited for light-duty controlled end-force applications in precision assemblies, tooling fixtures, jigs, and mechanical positioning systems. Its compact body fits in space-restricted installations where standard or heavy-duty plungers are too large. The stainless steel construction makes it appropriate for environments requiring corrosion resistance, including food processing, laboratory, and marine-adjacent applications. The maximum ball reach of 0.025 inches limits protrusion, making it effective for shallow-engagement detent points. No locking element is included, allowing the plunger to thread directly into a prepared hole without secondary locking hardware.

Key Features

• 10-32 thread for direct installation into standard tapped holes
• Stainless steel body and ball for corrosion resistance
• 1.5-pound initial end force and 3-pound final end force for controlled, repeatable positioning
• 0.094-inch ball diameter with 0.025-inch maximum ball reach for shallow-engagement detent applications
• Compact 0.513-inch body length - one of the smallest and lightest spring-loaded plunger designs in this class
• Color-coded purple for quick field identification

Compatibility

Designed as a direct-install spring-loaded ball plunger for any assembly or fixture with a 10-32 tapped hole requiring controlled end-force positioning.

Installation Notes

Installation is performed by threading the SSB52 into a prepared 10-32 tapped hole using standard hand tools. Ensure the receiving hole is clean and properly tapped to full depth before installation. Because no locking element is included, a thread-locking compound may be applied if vibration or back-out is a concern in the application. Disconnect or de-energize any related automated or powered mechanism before installing or servicing spring-loaded plungers in active assemblies.
