How the 57900 model number is decoded

  • 57900WIX hydraulic cartridge element part number.
  • 111.9 mm OD / 66 mm IDCartridge envelope (outside/inside diameter); no mounting thread.
  • PaperFilter media: Paper.

Typical equipment & applications

  • Mobile and industrial hydraulic return circuits
  • Construction and agricultural equipment
  • Heavy-duty transmission and torque-converter circuits

Selection pitfalls — read before you substitute

  • A return-line element is not a pressure-line element: return cartridges (low-collapse) tolerate roughly 20 bar differential, while BH4HC pressure executions are rated to 210 bar. Installing a low-collapse element in a pressure housing can rupture the media on cold-start spikes.
  • This element has no integral bypass — opening pressure is set by the housing’s reusable bypass valve. Confirm the valve setting (commonly 3.4 bar) is present before fitting.
  • “10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.
  • Nitrile (NBR) seals are standard for mineral hydraulic oil but fail early in some phosphate-ester fluids and at sustained high temperature; verify seal compound against the fluid data sheet (fluorocarbon/Viton executions may be required).
  • End-cap geometry and the number/position of O-rings block interchange even when OD and length match — visually compare end caps before fitting, especially with aftermarket cartridges.

Frequently asked questions

What are the dimensions of the 57900 filter element?
The published envelope is 111.9 mm OD × 457.2 mm length with a 66 mm inside diameter (4.406 × 18.000 in × 2.598 in ID). Confirm against the housing drawing before ordering.
What micron rating does 57900 use?
This element is rated 21 µm (nominal class). Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.
What replaces the 57900 filter element?
Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.
How do I read the 57900 part number?
See the designation decoder above: each segment of 57900 encodes size, line type, filtration grade and media/collapse execution.
Is a same-envelope aftermarket element always a drop-in replacement?
No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
How often should a hydraulic return-line element be replaced?
Replace at the housing manufacturer’s recommended differential-pressure setting (commonly signalled by a clogging indicator), or on a time-based service interval when no indicator is fitted — never wait for bypass to open continuously, because unfiltered oil then reaches the valves.
