This is the least expensive of the 2 ways you can power a model 600 series tubing bender. This is an air/hydraulic ram (It takes in compressed air and uses a small pump to convert that energy to high-pressure hydraulic flow to power the cylinder). This is ready to use right out of the box. They ship assembled with an air pump and hose. This cylinder is power extend ONLY. Our M600 bender includes a custom bracket and custom CNC-wound zinc-plated ASTM PW steel return springs for reliable return of this exact cylinder. When we sell these cylinders, we check the oil level and top them off as needed, make sure they don’t leak, verify that the return force is within our specifications, and then we also add our CNC machined release knob to the hydraulic valve. All the parts we make that attach to this cylinder are made here in the USA.

We have 3 suppliers for these cylinders. You will get one of them. They are as follows:

  1. Northern Tool, PN 46200 (RED) These cylinders are 24.95″ eye-to-eye when collapsed. This is the ABSOLUTE longest cylinder that will fit in the machine. They extend 19″ (travel), and which is more than necessary.
  2. Harbor Freight  PN 58816 (BLACK) or 56215 (RED, No longer in production) or 94562 (ORANGE, No longer in production, identical to 56215 other than packaging and paint color). Our photo shows the orange one. These cylinders have had a few slight changes over the years and have been available with slight interruptions for over a decade. These cylinders have 24 3/4″ collapsed length (eye-to-eye) and 19.25″ travel, which is an ideal match for our machinery. PLEASE NOTE THERE HAVE BEEN SOME FITMENT ISSUES REPORTED WITH THESE RAMS.

  3. Rogue Fab imported PN 1194 (BLACK or RED). As of 2023, this is the only cylinder we are shipping with our machines (only due to supply chains, there are no problems with the other cylinders). This company does not sell to the public. These are made for us overseas. We will always have these in our supply chain, although import practices can cause interruptions in stock levels (backorders). The length and travel on these cylinders match the Harbor Freight cylinders. Sometimes we have to work on these cylinders and the paint gets chipped on them in the areas we make adjustments or changes. We know this is not ideal. Please understand that the paint may not be as nice as other parts of the machine.

Important note – This is the only major component of the M600 series bender that is imported. If you want a high-quality, custom hydraulic solution to go with your bender, we offer (2) different electric/hydraulic power systems that are excellent (both feature Made-in-USA cylinders). If you wish to buy the hydraulic cylinder yourself to save money, we absolutely encourage you to buy the cylinders listed here directly from the distributors we purchase them from (that is precisely why we told you who sells them and the correct part number). If you are bargain shopping for a cylinder not listed above, keep in mind that the mounting holes on our machine are 5/8″ in diameter. Also, know that the Northern Tool cylinder is the longest one that will fit. Our return spring bracket is designed to clamp on ONLY 33mm hydraulic shafts. If you purchase a hydraulic cylinder with a smaller hydraulic shaft, it may not be able to utilize our spring return system.

Air requirements – These cylinders all consume about 6 CFM of compressed air at 110 psi while operating. They will run at lower pressures and make less force, and they will run at lower CFM and run slower. We recommend a 6+ CFM air compressor that can make 125 psi (set to 115-120). A 30+ gallon tank is recommended, but again, smaller will work (it will just cycle a lot more). We also recommend an “iron front” and oiled compressor. The new “oilless” ones are not reliable long term in our opinion.
