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

Product Description

The GIBRALTAR SSWPFN10-8B-G is a press fit ball plunger designed for positioning, indexing, and light-duty detent applications in mechanical assemblies. The stainless steel body is passivated for corrosion resistance, while the nylon ball provides smooth, low-friction engagement. At 0.5 inches in body diameter and 1.1 inches in overall length, this plunger installs by pressing directly into a drilled or reamed hole — no threading required. An integrated flange seats flush against the mating surface and controls insertion depth. Initial end force is 8 pounds and final end force is 18 pounds, making it suitable for consistent, repeatable positioning under moderate load.

This ball plunger is used in machine tool fixtures, jigs, slides, and general industrial assemblies where a compact detent or positioning element is needed. The flanged body style is common in precision tooling applications where axial retention is required without adhesive or set screws. It is typically installed by a machinist or maintenance technician during fixture build or equipment assembly. The nylon ball is appropriate for light-contact applications where the mating surface must not be marred.

Key Features

• Press fit installation — no threading, installs directly into a drilled or reamed bore
• Passivated stainless steel body for corrosion resistance in washdown or high-humidity environments
• Nylon ball provides smooth, non-marring detent engagement
• Integrated flange controls insertion depth and provides positive seating against the mating surface
• 8-pound initial force and 18-pound final force for consistent, repeatable positioning
• Compact form factor — 0.5 inches body diameter, 1.1 inches body length

Compatibility

Designed as a standard press fit ball plunger for use in machine tool fixtures, jigs, slides, and general mechanical assemblies requiring a flanged, non-threaded positioning or detent element.

Installation Notes

Installation is performed by a machinist or mechanical technician using a press or arbor press to seat the plunger body into a properly sized drilled or reamed hole. The mating bore should be sized to the body diameter tolerance specified for press fit applications to ensure secure retention. Do not hammer the plunger directly without a suitable driver, as this may damage the flange or distort the body. Ensure the assembly is de-energized and secured before servicing any equipment in which the plunger is being replaced.
