Jergens 49516 Reverse Mount Receiver Bushing Ball Lock

Product Description

The JERGENS 49516 is a reverse mount modular fixturing receiver bushing designed for use with Ball Lock quick-change fixturing systems. It features a 13mm inside diameter and a 0.787-inch outside diameter, with an overall installed height of 0.475 inches. The bushing mounts from the underside of a base plate and accepts a 13mm clamp shank, allowing workholding components to be located and locked with precision and repeatability. Machinists, toolroom technicians, and fixture builders use this bushing when building modular workholding setups on machining centers and tombstones where fast pallet or fixture changeover is required.

This bushing is suited for modular fixturing applications in both job shop and production machining environments. It is designed for installation into base plates with a minimum thickness of 0.75 inches. The reverse mount configuration positions the bushing from below the plate, keeping the working surface clear of protrusions. It is a standard component in Ball Lock compatible fixturing builds and is used wherever repeatable, tool-free fixture changes are needed on vertical or horizontal machining centers.

Compatibility

Compatible with Ball Lock modular fixturing systems using a 13mm clamp shank diameter. Designed for installation into base plates with a minimum thickness of 0.75 inches.

Installation Notes

Installation is performed by toolroom technicians or skilled machinists. Ensure the base plate is at least 0.75 inches thick before boring the receiver hole. The machine should be fully powered down and any workholding pressure released before removing or installing receiver bushings. Follow the fixturing system manufacturer guidelines for bore tolerances and surface finish to ensure proper bushing retention and repeatable location accuracy.
