Locks The Ball Lock™ System securely holds fixture plates to subplates with up to 20,000 lbs. (88kN) of hold-down force per shank. Ball Lock™ Fixture Mounting System for Jergens Production Vises The Ball Lock™ Mounting System provides a method of quickly and accurately locating fixtures onto machine tables. The Ball Lock™ Mounting System has done for machining centers what the Japanese SMED (Single Minute Exchange of Die) concept did for presses. Instead of SMED, Ball Lock™ provides single minute exchange of fixtures. Fixtures can often be exchanged in less than a minute with position repeatability of ±0.0005” (±0.013mm). Fixtures can be exchanged between different machines when both are using the Jergens Ball Lock™ Mounting System. Commonly Asked Questions Q. What is the Ball Lock™ Mounting System? A. It is a means of locating and locking two flat surfaces together, normally a fixture plate to a sub-plate. Q. How does it locate? A. Similar to locating pins, two Ball Lock™ shanks (pins) pass through two precision liner bushings on the fixture plate and into two precision receiver bushings on the subplate. Q. How does it lock? A. Inside the shank are three balls that expand into a tapered groove in the receiver bushing. This action draws the plates together. The locking balls are activated by turning a setscrew in the head of the shank, which pushes a 4th ball to distribute the clamping forces between the 3 locking balls. Q. How many shanks are required to locate and lock each fixture? A. Only two shanks, passing through bushings in the fixture plates, are required for location. However, additional shanks passing through clearance holes in the fixture plate will provide additional holding force distributed across the plate.
