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, and its RJ series runs 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 Marathon RJ-series compactors — matched bore, rod diameter, stroke length, mounting style, and port configuration.

How to choose

Identify the cylinder by Marathon model (RJ-225, RJ-250, etc.) and the OEM cylinder part number. PRT customer service can confirm a direct equivalent from the model alone.

If the original cylinder on your Marathon RJ compactor is leaking or losing force, a PRT replacement cylinder drops into the existing mounting location with no modification.

Marathon cylinder applications

  • Marathon RJ ram cylindersFor the RJ-series stationary compactors — the most common Marathon line.
  • Marathon tailgate cylindersOpen and close tailgates on self-contained Marathon compactors.

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.

How fast does PRT ship Marathon cylinders?

Most in-stock Marathon RJ cylinders ship same business day. Specialty configurations (oversized, custom port positions) may ship in 3-5 business days.
