Jergens 49608 Ball Lock Modular Fixturing Shank 16mm

Product Description

The JERGENS 49608 is a Ball Lock modular fixturing shank designed for use in precision workholding setups on CNC machining centers and fixture plates. Machined from steel with a black finish, this shank provides a maximum holding force of 1,200 pounds, delivering repeatable, rigid clamping without the need for additional fasteners. The 16 mm shank diameter seats into a Ball Lock receiver bushing in the fixture plate, allowing fast changeover between setups. Licensed toolmakers, fixturing specialists, and CNC machinists install this component when building modular, quick-change workholding systems.

This shank is suited for horizontal and vertical machining center fixtures where consistent, repeatable part location is required. With a shank length of 1.4 inches, a head diameter of 1.5 inches, and an overall length of 1.72 inches, it is well matched to standard fixture plate layouts. The 1/8-inch key size indexes the shank rotationally, ensuring precise angular alignment every time the plate is changed. Typical applications include production runs requiring frequent fixture swaps and tombstone or grid-plate fixturing systems.

Key Features

• Ball Lock interface delivers up to 1,200 pounds of maximum holding force for rigid, vibration-resistant clamping
• 16 mm shank diameter for direct installation into standard Ball Lock receiver bushings
• 1/8-inch key provides positive rotational indexing for repeatable angular alignment
• Steel construction with black finish for corrosion resistance and durability in machining environments
• Compact overall length of 1.72 inches minimizes Z-axis stack height on fixture plates
• Head height of 0.32 inches and head diameter of 1.5 inches seat flush and securely against plate surfaces

Compatibility

Compatible with Ball Lock system fixture plates having a plate thickness compatibility of 0.75 inches. Designed as an OEM-style replacement or addition for Ball Lock modular fixturing systems using 16 mm shank receiver bushings.

Installation Notes

Installation is performed by qualified toolmakers or CNC setup personnel. Ensure the machine spindle is powered down and all motion is stopped before handling fixture components. The receiver bushing bore in the fixture plate must be clean and free of chips before inserting the shank. Apply the locking mechanism per the Ball Lock system procedure and verify positive engagement before applying any machining loads.
