Jergens 49502 Ball Lock Receiver Bushing 25mm Bolt-in

Product Description

The JERGENS 49502 is a bolt-in recessed modular fixturing receiver bushing designed for use with Ball Lock quick-change workholding systems. It accepts a 25mm clamp shank diameter and provides a secure, repeatable mounting interface for fixture plates and subplates on machining centers and tooling setups. The outside diameter measures 2.0623 inches with an overall height of 0.799 inches. Three mounting holes are arranged on a 1.644-inch bolt circle, allowing the bushing to be firmly anchored into a base plate. This component is installed by machinists and tooling engineers working in precision fixturing environments.

This receiver bushing is suited for production and job-shop machining applications where fast, repeatable fixture changeovers are required. It installs in a recessed bore within a base plate, requiring a minimum base plate thickness of 1.25 inches. The Ball Lock system interface allows fixture shanks to engage and lock with consistent positional accuracy, reducing setup time between operations. It is appropriate for use in milling, drilling, and multi-operation machining setups where modular fixturing is part of the workflow.

Key Features

• Ball Lock system compatible for fast, repeatable fixture changeovers
• Bolt-in recessed mount with 3 mounting holes on a 1.644-inch bolt circle
• 25mm inside diameter matches standard Ball Lock clamp shank diameter
• Outside diameter of 2.0623 inches for precise bore fit
• Overall installed height of 0.799 inches suits low-profile base plate designs
• Requires minimum base plate thickness of 1.25 inches for proper installation

Compatibility

Designed for use with Ball Lock modular fixturing systems accepting a 25mm clamp shank diameter. Verify base plate bore dimensions and minimum thickness of 1.25 inches before installation.

Installation Notes

Installation is performed by a machinist or tooling engineer. Before installation, ensure the machine table or base plate is depressurized or de-energized as applicable, and that all clamping forces are fully released. The base plate must be bored and spot-faced to accept the recessed bushing profile, with a minimum plate thickness of 1.25 inches confirmed prior to assembly. Use appropriate torque specifications from the JERGENS installation documentation for the three mounting fasteners - do not estimate fastener torque.
