Price Beat Guarantee: We've crawled the internet to guarantee you're getting the best price. Here's what competitors are selling this exact filter for:
You're saving approximately 20% on Rexroth R900224821 buying from SPM.
Industrial power units
Rexroth filters sit on the power units of presses, machine tools, plastics machines and test rigs. A fresh element keeps servo and proportional valves at the cleanliness they were designed for.
Mobile and construction machinery
Rexroth hydraulics drive tunnel boring machines, concrete pumps and cranes, where a spare element on site saves a breakdown call.
Steel, paper and energy plants
Rolling mill, paper machine and turbine control oil systems often run Rexroth or Rexroth sized filters. Holding spares means the change can happen as soon as the clogging indicator trips.
Planned maintenance stock
Sites with several machines on the same element can hold stock for scheduled changes at a lower price than buying OEM every time.
