Gibraltar 10629SS Press Fit Ball Plunger 0.188 in Dia

Product Description

The GIBRALTAR 10629SS is a press fit ball plunger designed for use in positioning, indexing, and light-duty locking applications across mechanical assemblies. The body is constructed from stainless steel for corrosion resistance, while the ball element is Delrin for controlled friction and smooth actuation. The plunger measures 0.188 inches in body diameter and 0.44 inches in body length. It delivers an initial end force of 2 pounds and a final end force of 5 pounds, making it suited for applications requiring repeatable, spring-loaded detent action. Machinists, tool and die technicians, and assembly line maintenance personnel are the typical installers.

This press fit ball plunger is intended for installation into pre-drilled or reamed bores in metal, plastic, or composite fixtures and machine components. It is commonly used in jigs, fixtures, tooling plates, drawer slides, rotating assemblies, and panel retention applications where a low-profile, flush-mount detent mechanism is required. The press fit design eliminates the need for threads, allowing fast installation in production environments. The Delrin ball provides consistent travel across repeated actuation cycles without galling the mating surface.

Key Features

• Stainless steel body for corrosion resistance in wash-down and humid environments
• Delrin ball material reduces friction and resists galling on contact surfaces
• Press fit installation into 0.188 inch diameter bores — no threading required
• 0.3120 inch ball diameter with a maximum ball reach of 0.058 inches
• 2 pound initial force and 5 pound final force for consistent detent action
• No flange and no locking element — compact, low-profile form factor

Compatibility

Designed for press fit installation into bores sized to accept a 0.188 inch diameter body. Suitable for use in metal, plastic, and composite assemblies requiring a spring-loaded detent or positioning element.

Installation Notes

Installation is performed by pressing the plunger body into a properly sized bore using an arbor press or similar controlled-force tool. The bore should be clean and within tolerance for the 0.188 inch press fit diameter to ensure secure retention. No adhesives or fasteners are required. Always verify bore depth against the 0.44 inch body length before pressing to avoid bottoming out and damaging the spring mechanism.
