Gibraltar SSWPF10-4BL-G Ss Press Fit Ball Plunger 0.25in

Product Description

The GIBRALTAR SSWPF10-4BL-G is a stainless steel press fit ball plunger designed for light-duty positioning, indexing, and detent applications in mechanical assemblies. The flanged body measures 0.25 inches in diameter and 0.0471 inches in body length, with a stainless steel ball that extends up to 0.07 inches at maximum reach. Initial end force is 1.5 pounds, with a final end force of 3.5 pounds, making it suited for applications requiring a consistent, repeatable tactile detent. Both the body and ball are stainless steel with a passivated finish for corrosion resistance. Machinists, maintenance technicians, and assembly professionals install this type of hardware in fixtures, jigs, and precision equipment.

This ball plunger is press fit into a mating bore and relies on the flanged design to control insertion depth. The flange diameter is 0.312 inches and the flange thickness is 0.045 inches, with a length under flange of 0.471 inches. It is used in light industrial, manufacturing, and OEM equipment applications where a non-locking, spring-loaded detent point is required. The passivated stainless steel construction makes it appropriate for environments with moisture exposure or cleanliness requirements such as food processing adjacent equipment or medical device assemblies.

Key Features

• Stainless steel body and ball with passivated finish for corrosion resistance
• Press fit installation — no threading required, seats directly into a bored hole
• Flanged design controls insertion depth; flange diameter 0.312 inches
• 1.5 lb initial force and 3.5 lb final force for consistent detent action
• Maximum ball reach of 0.07 inches suits shallow detent groove applications
• Non-locking spring element allows free ball movement without retention lock

Compatibility

Designed as a press fit flanged ball plunger for installation into machined bores sized to accept a 0.25-inch diameter body; verify bore tolerance and fit class before installation to ensure proper retention and detent force.

Installation Notes

Installation is performed by pressing the plunger body into a precision-machined bore using a press or arbor press — do not hammer directly on the ball or flange face. Verify bore diameter and depth match the body and under-flange dimensions prior to pressing. No threading or adhesive is required, but interference fit tolerances must be correct to maintain rated end forces. This hardware is typically installed by machinists or mechanical assemblers working with fixtures, tooling, or OEM equipment.
