Gibraltar 10612SS Press Fit Ball Plunger 0.5 in Dia

Product Description

The GIBRALTAR 10612SS is a press fit ball plunger machined from stainless steel, designed for indexing, positioning, and light detent applications in mechanical assemblies. The body measures 0.5 inches in diameter and 1.218 inches in length. A stainless steel ball with a 0.312-inch diameter extends up to 0.161 inches beyond the body face. Initial end force is 8 pounds and final end force is 18 pounds, giving the plunger a firm, predictable snap action. This part is installed by machinists, toolmakers, and maintenance technicians in production and MRO settings.

This ball plunger is suited for press-fit installation into drilled holes in jigs, fixtures, tooling plates, machine frames, and similar assemblies. The stainless steel construction makes it appropriate for environments where corrosion resistance is a priority, including food-processing equipment, washdown areas, and outdoor or humid industrial settings. No locking element or flange is present on this model, keeping the profile compact for tight clearance installations.

Installation Notes

A licensed machinist or maintenance technician typically installs press fit ball plungers using a arbor press or bench vise to seat the body flush without damaging the ball mechanism. Ensure the receiving bore diameter and depth match the plunger body dimensions before pressing. De-energize and lock out any powered equipment before servicing an assembly that contains this plunger. Do not strike the ball directly during installation, as impact can deform the ball seat and alter force characteristics.
