Jergens 49506 Receiver Bushing 13mm Ball Lock

Product Description

The JERGENS 49506 is a bolt-in recessed modular fixturing receiver bushing designed for use with Ball Lock quick-change fixturing systems. It provides a precision-fit mounting interface that accepts a 13mm clamp shank diameter, allowing repeatable, tool-free workholding changes on machining and fixture plates. With an outside diameter of 1.375 inches and an overall height of 0.469 inches, this bushing mounts flush or recessed into a base plate, keeping the work surface clean and unobstructed. Three mounting holes on a 0.984-inch bolt circle secure the bushing rigidly to the plate. It is installed by machinists, toolmakers, and fixture builders in production and job-shop environments.

The 49506 is suited for modular fixturing setups in CNC machining centers, milling, and multi-pallet applications where rapid workholding changeover is required. It requires a minimum base plate thickness of 0.75 inches to ensure proper bolt-in retention and full shank engagement. The recessed mount style keeps the bushing below the top surface of the base plate, reducing interference with workpieces and fixtures. This bushing is compatible with Ball Lock system components and is sold individually.

Key Features

• Bolt-in recessed mount style seats the bushing below the base plate surface
• Accepts 13mm Ball Lock clamp shank diameter for repeatable quick-change fixturing
• Three-hole mounting pattern on a 0.984-inch bolt circle for rigid, secure retention
• Outside diameter of 1.375 inches fits standard Ball Lock receiver cutouts
• Requires a minimum base plate thickness of 0.75 inches for full engagement
• Compact overall height of 0.469 inches minimizes stack-up in tight fixture layouts

Compatibility

Designed for use with Ball Lock modular fixturing systems. Compatible with components using a 13mm clamp shank diameter. Confirm bolt circle and base plate thickness requirements before installation.

Installation Notes

Installation is performed by toolmakers or machinist personnel using standard drill, counterbore, and tapping equipment to prepare the base plate. The base plate must be at least 0.75 inches thick to provide adequate thread engagement for the mounting bolts. Power down and de-energize any associated machine before installing or removing receiver bushings. Verify that the bolt circle pattern and counterbore depth match the 49506 specifications before final assembly.
