Gibraltar SWPF10-3B-G Steel Press Fit Ball Plunger

Product Description

The GIBRALTAR SWPF10-3B-G is a press fit ball plunger designed for positioning, indexing, and light detent applications in mechanical assemblies. The body is steel with a black finish, and the ball is stainless steel for corrosion resistance at the contact point. The plunger body measures 0.188 inches in diameter and 0.0394 inches in length, with a flanged design that seats flush against the mating surface during installation. Initial end force is 2 pounds and final end force is 5 pounds, making this part suited for light-duty detent and locating functions in tooling, fixtures, and precision assemblies.

This ball plunger is used in industrial and mechanical applications where a spring-loaded ball is needed to locate, retain, or index a moving component. Typical installations include jigs, fixtures, tooling plates, machine components, and light-duty assembly equipment. The press fit body allows for tool-driven installation into a drilled hole without threading, simplifying integration into new or existing assemblies. The flanged body provides a positive stop to control insertion depth.

Key Features

• Steel body with black finish and stainless steel ball for durability at the contact surface
• Press fit installation into a drilled hole — no threading required
• Flanged body controls insertion depth with a positive stop
• 2 pound initial end force and 5 pound final end force for light-duty detent applications
• Ball diameter of 0.094 inches with a maximum ball reach of 0.058 inches
• Compact profile: 0.188 inch body diameter, 0.0394 inch body length, 0.25 inch flange diameter

Compatibility

Designed as a standard press fit ball plunger for use in drilled holes in jigs, fixtures, tooling plates, and light mechanical assemblies requiring a 0.188 inch body diameter fit.

Installation Notes

Installation is performed by pressing the plunger body into a precisely drilled through-hole or blind hole sized to the 0.188 inch body diameter. A press or suitable driver tool should be used to seat the flange flush against the workpiece surface. Verify hole diameter and depth before pressing to avoid damaging the ball mechanism. No special codes govern this hardware, but standard machining tolerances for press fit components should be followed.
