The Pro Pallet System

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. This manual pallet changer simultaneously improves productivity by reducing labor and idle spindle time.

Pro Pallet System Base

The PPS Base uses dual ball lock mechanisms to provide 3,000 lbs of locking force and 15,000 lbs of retention force. The failsafe system is air actuated for 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.

Base Features

  1. Face Seal diverts chips and coolant
  2. Pallets locate on Hardened Pins
  3. Thermally Stable Cast Iron Core
  4. Hardened Stainless Ball Locks
  5. Hard Anodized Aluminum Body

Q&A: More than Just for Fixtures

Take a deep dive with BladesIIB and see how Bud is harnessing the power of his PPS.


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.

The Pierson PPS provides all the efficiencies of high density workholding and fast part change-outs without the astronomical price tag.

Yes! Three options are available. First, we can make custom oversized pallets. Give us a call or email for exact sizing and pricing. Second, YOU can make an oversized pallet using our PPS Hardware kit. Make sure to watch this video to program your part for best success. Finally, a custom double receiver pallet is an option for holding one large pallet using two bases. Contact us for details.

A 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! Check out this video to see how customers standardize vises, indexers and clamping fixtures for single minute setups. 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! For more ideas on what people are mounting to their pallets, check out our Instagram feed.

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.

Yes, substituting a different size pallet for the 8 x 12 that comes with the Starter Package is not a problem. Our workholding store will automatically quote the price for different pallets.
