Our 4th generation Pro Pallet System (PPS) builds on over a decade of refinements. The PPS is a high-density workholding solution designed to eliminate bottlenecks by allowing more parts to be held AND moved in and out of the machine faster than any other workholding method. The universal Base accepts four standard sizes of pallets (also known as fixture plates). This manual pallet changer simultaneously improves productivity and reduces labor.
Pro Pallet System Starter Package
The Pro Pallet System (PPS) Starter Package streamlines purchasing. We’ve even discounted the system so you know you’re buying smart. Add to Cart and select the size of pallets you want with the package.
The PPS Base uses dual ball lock mechanisms to provide 3000 lbs of downward force. The failsafe system is air actuated to release and spring powered to lock. Repeatability is .0003″ due to the precision ground locating pins. The combination of cast iron, hard-anodized aluminum and hardenend stainless components ensures excellent rigidity and tough wear resistance.
Pallets range in size from 8″x12″ to 10″x16″ and locate with .0003″ repeatability. 6061-T6 Extruded Aluminum assures easy machinability. The bottom locking surfaces use hardened stainless steel for long life. The tops are blank and ready to customize.

This connection kit gives you peace of mind ensuring you’ll have all the proper components to be up and running within minutes of opening the box. Plus, only one hand valve is needed to operate multiple bases when chained together. Kit is included in Starter Packages.
Adding vacuum workholding capabilities to the PPS is easy with this Vacuum Pallet Kit (VPK). This kit includes our Vacuum Power Unit, Connection Kit, 25′ of Vacuum Gasket (not shown) and a 9.5″ x 14″ vacuum chuck which locks onto the MPS Base as easily as other pallets.
Look at any high production machine out there and you'll see pallet changers, tombstones, and high density workholding fixtures. The industry has figured out that to maximize profits you have to maximize spindle time. The more parts you can get in a machine per cycle and the faster you can get them in and out translates into bigger profits. The problem is that these "efficiencies" have such a high initial cost that you might not see any return on investment until several years down the road. ThePierson PPS provides all the efficiencies of high density workholding and fast part change-outs without the astronomical price tag.
Several reasons. First of all, vises rely on holding objects using brute clamping force. Our workholding systems hold pallets with a downward force. Once locked, resistance to movement in the X and Y directions are not dependent on clamping pressure. This downward locking method assures that there is no excessive pressure exerted on the pallet which might cause distortion or bowing.
Second, the system has a repeatability of .0002. With vises, the constant clamping and unclamping distorts a pallet either by bowing it or by compressing the material so much that accuracy starts declining from the first crank of the vise handle. Since the system is air actuated, you'll never have to deal with a vise handle again. It's as simple as flipping a single hand valve. Best of all, you'll be swapping fixtures in and out of the machine in about 15 seconds. No vise can compete with that!
Finally, pallets are easy to install and ready to go right out of the box. They also come in sizes that would not be able to be held in a standard capacity vise without time consuming modifications. This means faster fixture creation and more parts per fixture.
An PPS will work with any vertical machining center or knee mill. The Connection Kit contains all the components needed (air fittings, air lines, hand valve, grommets, instructions) to begin using the PPS in your machine. The only other thing you'll need to provide is an air source with a minimum of 100psi for operation. Mounting the PPS Base is easy. The PPS Base mounts to your table with the same T-slot nuts that a standard vise uses. We even include the toe clamps and bolts.
Vises have been around for a long time and have their right place in manufacturing. High density workholding systems don't have much benefit on prototype and short run jobs, but they are not always for holding parts! Many of our customers use our system to hold and store vises, indexers and clamping fixtures. Imagine bolting your current vises and rotary indexers to pallets and simply dropping them onto your table with no need to indicate them ever again!

Not at all. The PPS still maintains a tremendously high locking force of over 3000 lbs due to its powerful springs. This is more than enough to maintain a secure hold. Plus, other systems use hydraulics which can be a great liability of losing holding power should the hydraulic pump fail. The PPS is designed to be failsafe. The air lines can be completely removed and the system will continue to stay locked.
Spreading a light coating of grease on the alignment pins and locking bearings is all you'll need to do to ensure consistent holding force. This should be done on a regular maintenance schedule as outlined in the PPS Manual. Because all critical components are hardened, the system has shown very little wear after 100,000 test cycles. We've found that the best preventive maintenance is to keep everything clean, covered and dry when not in use.
