Validated Hydraulic Fluids for Increased Hydraulic Life

Development Hydraulics

Over the past few years, the efficiency of hydraulic systems has again risen considerably. This also increases the demands that are made on the hydraulic fluids that are used, since they can have a crucial effect on the wear properties of hydraulic components. Relevant standards only define the minimum requirements of hydraulic fluids. They do not reflect further technical developments and do not make it possible to differentiate between the fluids. Bosch Rexroth offers the manufacturers of lubricants and additives a standardised assessment procedure based on scientific knowledge, which takes these aspects into account and tests the hydraulic fluids for suitability under realistic application conditions.


Due to increasing operating pressures, speeds, oil circulation and temperatures, the power density has risen considerably over the last few years. This means that the power-to-weight ratio for axial piston pumps and motors has more than doubled over the last few decades....
