Jergens 49601 Ball Lock Modular Fixturing Shank 20mm

Product Description

The JERGENS 49601 is a Ball Lock modular fixturing shank designed for use in tooling plate and fixture setups that demand repeatable, high-force clamping. Machined from steel with a black finish, this shank delivers a maximum holding force of 3,000 pounds and accepts a 1/8 inch key for precise angular location. With a shank diameter of 20mm (0.787 inches) and a shank length of 1.53 inches, it integrates directly into Ball Lock receiver bushings mounted in fixture plates up to 0.75 inches thick. Machinists, fixture builders, and toolroom technicians install this component as part of modular workholding systems on machining centers and manual mills.

This fixturing shank is suited for production and prototype environments where quick-change tooling plates must index accurately and hold rigidly under cutting loads. The Ball Lock system allows a single shank to be engaged or released at the fixture plate without disturbing part location. It is appropriate for both horizontal and vertical machining center applications where plate thickness compatibility of 0.75 inches is met. The overall installed length of 1.91 inches keeps the shank profile compact within tight fixture assemblies.

Key Features

• Maximum holding force of 3,000 pounds for rigid workholding under load
• 20mm shank diameter compatible with standard Ball Lock receiver bushings
• Plate thickness compatibility of 0.75 inches for proper engagement depth
• 1/8 inch key size provides positive angular orientation at installation
• Steel construction with black finish for durability and corrosion resistance
• Compact overall length of 1.91 inches suits space-constrained fixture designs

Compatibility

Designed for use with Ball Lock modular fixturing systems requiring a 20mm shank diameter and a receiver plate thickness of 0.75 inches.

Installation Notes

Installation is performed by toolroom technicians or fixture builders familiar with modular workholding systems. The fixture plate must be de-energized and free of any active clamping pressure before inserting or removing the shank. Verify receiver bushing alignment and plate thickness match the shank specifications before final assembly. Use the 1/8 inch key slot to set angular orientation prior to engaging the ball lock mechanism.
