Gibraltar SSWPFN10-8BL-G Press Fit Ball Plunger 0.5 in

Product Description

The GIBRALTAR SSWPFN10-8BL-G is a press fit ball plunger with a stainless steel body and nylon ball, designed for positioning, indexing, and light detent applications in industrial and mechanical assemblies. The body measures 0.5 inches in diameter and 1.1 inches in length, with a passivated finish for corrosion resistance. Initial end force is 4 pounds and final end force is 9 pounds, giving this plunger a defined spring-loaded engagement range suited for repeatable positioning tasks. A flanged body design aids in positive seating during press installation. Machinists, tool and die technicians, and assembly technicians are the primary installers of this fastener-class component.

This ball plunger is used in jigs, fixtures, tooling plates, and light-duty mechanical assemblies where a spring-loaded nylon ball provides soft, low-friction detent or positioning action. The press fit body installs directly into a drilled bore without threads, making it suitable for applications where a clean, flush-mount installation is required. The flanged design prevents the plunger from being pushed through the bore during installation or service. Typical applications include panel positioning, drawer alignment, and component staging in manufacturing or maintenance environments.

Key Features

• Stainless steel body with passivated finish for corrosion resistance
• Nylon ball provides low-friction, soft-contact detent action
• Press fit installation into a drilled bore — no threading required
• Flanged body at 0.688 inches flange diameter prevents blow-through during press installation
• Spring force range from 4 pounds initial to 9 pounds final end force
• Ball reach of 0.161 inches and ball diameter of 0.312 inches for consistent engagement depth

Compatibility

Designed as a press fit replacement or new-installation ball plunger for jigs, fixtures, tooling plates, and light mechanical assemblies requiring a flanged, non-threaded detent component with a nylon ball.

Installation Notes

Installation is performed by pressing the plunger body into a precision-drilled bore sized to the 0.5-inch body diameter using an arbor press or similar controlled-force tool. Ensure the bore depth and diameter are machined to specification before installation to achieve proper flange seating. No adhesives or locking elements are incorporated in this design, so bore fit tolerance is critical to retention. De-energize or lock out any machinery before servicing assemblies containing this component.
