What to Look for When Buying Used Jergens Workholding
Jergens workholding is manufactured from case-hardened steel and precision-ground materials designed for years of repeatable service. Used Ball Lock systems, ZPS modules, and fixture plates frequently retain excellent accuracy.
On Ball Lock fixture plates and subplates, check the receiver bushings and shank seats. The Ball Lock system depends on clean, undamaged receiver bushings in the subplate and properly functioning ball-lock shanks in the fixture plate. Inspect each receiver bushing bore for scoring, corrosion, or debris that would prevent the balls from engaging cleanly. Test the lock and release action on every bushing. Verify the fixture plate sits flat on the subplate with no rock, and indicate across the plate surface to confirm flatness is within the original 0.001" specification.
On ZPS zero-point modules, verify clamping force and positioning repeatability. Connect the pneumatic or hydraulic supply and cycle each module through clamp and release. Confirm positive locking at each station with no creep under load. Verify the centering pins engage cleanly and that the module pulls the fixture down with full force. ZPS modules should deliver positioning repeatability within 0.0002" when properly maintained.
On vises and clamps, inspect jaw condition and clamping mechanism. On Bock twin vises, test the quick-change jaw system for smooth engagement and verify both stations clamp with equal force. On OK-Vise edge clamps, check the clamping screw and wedge mechanism for wear. On hydraulic clamps, verify seal integrity by cycling under pressure and watching for leaks or pressure drop.
Jergens Ball Lock® Mounting System
The Ball Lock system is Jergens' signature product and the industry standard for quick-change fixture mounting on machining centers. Fixture plates with ball-lock shanks drop into receiver bushings mounted in a subplate, and a quarter-turn of the lockscrew engages the balls for positive, repeatable location. The system eliminates the need for indicating fixtures during setup, saving significant time per changeover. Fixture plates are available in rectangular, round, and multi-purpose configurations in steel and 6061-T651 aluminum. Subplates (multi-purpose, standard, and custom) mount directly to the machine table. Ball Lock is compatible with VMCs, HMCs, and multi-pallet systems.
Jergens Zero Point System (ZPS) & Quick-Loc
The ZPS zero-point clamping system provides single-step fixture location and clamping with pneumatic or hydraulic release. Operators fix, position, and clamp in one motion, reducing setup time by up to 90%. ZPS modules mount directly to the machine table or to subplates and accept any fixture equipped with matching pull studs. The Quick-Loc pallet system uses a 4-pull-stud interface with square, rectangular, and round receivers in 52 mm and 96 mm patterns. Quick-Loc delivers repeatability of 0.0003" with clamping forces up to 14,000 lbs. The QL2 combination system merges 52 mm and 96 mm patterns in a single receiver.
Jergens Vises & Fixture-Pro 5-Axis
Bock Workholding CNC production vises (acquired by Jergens in 2008) feature the fastest quick-change jaw system available, with twin vise configurations for high-density setups. The compact 130 mm self-centering vise pairs with Quick-Loc for rapid changeover on 5-axis machining centers. The Fixture-Pro modular 5-axis system uses Drop & Lock pallet changers for quick fixture swaps. OK-Vise low-profile edge clamps grip from the side for maximum top-access machining, with Multi-Rail, Knife Grip, and hydraulic variants.
Jergens Power Clamping, Columns & Components
Hydraulic power clamping includes swing clamps, work supports, and Breadbox air-powered hydraulic pumps. Tooling columns in square, cross, and rectangular styles provide high-density HMC fixturing in Ball Lock, ZPS, or tapped grid configurations. Standard tooling components include rest buttons, clamp straps, V-blocks, locating pins, toggle clamps, and T-slot nuts.
How to Sell Your Used Jergens Workholding
Jergens workholding holds strong resale value due to the brand's dominant market position in quick-change fixturing, the enduring Ball Lock interface standard, and the high replacement cost of ZPS modules and custom fixture assemblies. Ball Lock plates, ZPS systems, and Bock vises are in consistent demand.

Frequently Asked Questions About Used Jergens Workholding
Are used Jergens Ball Lock systems reliable?
Yes. Ball Lock receiver bushings and shanks are manufactured from case-hardened steel with precision-ground contact surfaces. The ball-locking mechanism has no springs or complex parts to fatigue. A properly maintained Ball Lock system delivers repeatable positioning accuracy across thousands of fixture changes.
What is the difference between Ball Lock, ZPS, and Quick-Loc?
Ball Lock is a manual quick-change system (quarter-turn lockscrew) for fixture plate mounting. ZPS (Zero Point System) provides pneumatic or hydraulic single-step clamping for faster, automated changeovers. Quick-Loc is a modular pallet system using a 4-pull-stud interface for fixture and vise mounting. All three can be used independently or combined in the same setup.
What should I inspect before buying used Jergens workholding?
On Ball Lock systems, check receiver bushings and shank condition, plate flatness, and lock engagement. On ZPS modules, verify clamping force and repeatability under pneumatic or hydraulic pressure. On vises, test jaw quick-change function and clamping force. On hydraulic clamps, check for seal leaks.
What Jergens products hold their value best?
ZPS zero-point clamping modules, Ball Lock subplates and fixture plates, Bock twin vises, and cast iron tooling columns maintain the strongest resale values. Call (844) 478-8181 for current valuations.
