Jergens 49612 Ball Lock Modular Fixturing Shank 25mm

Product Description

The JERGENS 49612 is a Ball Lock modular fixturing shank designed for use in precision workholding systems on machine tool setups. The shank measures 25 mm in diameter and 1.95 inches in length, with a head diameter of 2 inches and an overall length of 2.33 inches. It delivers a maximum holding force of 7,000 lb, making it a reliable component for high-repetition fixture changeovers. Constructed from steel with a black finish, this shank is installed by machinists and toolroom technicians who require repeatable, zero-point-style fixturing performance on milling, drilling, or grinding operations.

This shank is suited for use with Ball Lock modular fixturing plates and receivers in production and job-shop environments where quick fixture changes are routine. It is compatible with plates up to 1 inch thick and accepts a 5/32 inch key for rotational orientation. Typical applications include palletized workholding on vertical machining centers and horizontal machining centers where consistent repeatability between setups is critical.

Installation Notes

Installation is performed by machinists or toolroom personnel. Power down and lock out the machine before installing or removing fixturing shanks. Verify the receiver plate bore and plate thickness are within the specified tolerances before seating the shank. Use the correct key size to ensure proper rotational orientation before engaging the ball lock mechanism.
