Marathon Compactor Cylinders & Ram Cylinder Replacements
Replacement hydraulic cylinders for Marathon trash compactors — ram cylinders, tailgate cylinders, and accessory cylinders. OEM-equivalent specs with the same bore, rod, stroke, and mounting as original Marathon cylinders. PRT already serves Marathon compactor operators across the US — most orders ship the same business day.
What this page covers
Marathon is one of the most common industrial compactor brands in North American commercial waste service — the RJ, EZ, and CF lines run in retail, restaurant, multifamily, and industrial installations across the country. The hydraulic cylinders that drive the Marathon ram are the most stressed component on the compactor, and they wear in predictable ways.
PRT manufactures and stocks OEM-equivalent replacement cylinders for the Marathon lineup — matched bore, rod diameter, stroke length, mounting style, and port configuration. We also stock rebuild kits with all the seal components for operators who prefer to rebuild rather than replace.
How to choose
Identify the cylinder by Marathon model (RJ-225, RJ-250, EZ-250, CF-225, etc.) and the OEM cylinder part number. PRT customer service can confirm a direct equivalent from the model alone.
If your Marathon compactor is more than 10 years old and the original cylinder is showing wear, consider a complete cylinder replacement instead of a rebuild — labor cost on a rebuild often exceeds the cost difference between a rebuild kit and a new cylinder.
Marathon cylinder applications
- Marathon RJ ram cylindersFor the RJ-series stationary compactors — the most common Marathon line.
- Marathon EZ ram cylindersFor the EZ-series self-contained compactors.
- Marathon CF cylindersFor Marathon's Compact Force compactor line.
- Marathon tailgate cylindersOpen and close tailgates on self-contained Marathon compactors.
- Marathon cylinder rebuild kitsPiston, rod, wiper, and O-ring seals for in-place rebuild.
- Custom Marathon-compatible cylindersBuilt to Marathon specs for legacy or non-current models.
Frequently asked questions
Are PRT Marathon-compatible cylinders OEM-spec?
Yes. PRT cylinders match Marathon OEM bore, rod, stroke, mounting, and port specifications. They drop into the existing mounting location with no modification.
How long does a Marathon ram cylinder typically last?
Typically 50,000-75,000 cycles in standard commercial service. Heavy-duty industrial use (food-service receiver containers, multi-shift manufacturing) can shorten that to 25,000 cycles.
Can I get a rebuild kit for a Marathon cylinder instead of a complete replacement?
Yes. PRT stocks complete rebuild kits with piston seal, rod seal, wiper seal, and O-rings. Rebuild only if the cylinder rod chrome and bore are in good shape — otherwise the new seals fail quickly.
How fast does PRT ship Marathon cylinders?
Most in-stock Marathon RJ and EZ cylinders ship same business day. Specialty configurations (oversized, custom port positions) may ship in 3-5 business days.
