Technical data Hydraulic fluid Details regarding the choice of hydraulic fluid Before starting project planning, please refer to our data sheets RE 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids), RE 90222 (HFD hydraulic fluids) and RE 90223 (HFA, HFB, HFC hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in an open circuit, the reservoir temperature. The fixed pump A2FO is not...

Technical data Filtration of the hydraulic fluid Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit. To ensure the functional reliability of the axial piston unit, a gravimetric analysis of the hydraulic fluid is necessary to determine the amount of solid contaminant and to determine the cleanliness level according to ISO 4406. A cleanliness level of at least 20/18/15 is to be maintained. At very high hydraulic fluid temperatures (90 °C to maximum 115 °C), a cleanliness level of at least 19/17/14 according to ISO...

Technical data Effect of radial force Fq on the service life of bearings By selecting a suitable direction of radial force Fq, the load on the bearings, caused by the internal rotary group forces can be reduced, thus optimizing the service life of the bearings. Recommended position of mating gear is dependent on direction of rotation. Examples: Determining the operating characteristics Vg • n • nv Flow qv = Vg = Displacement per revolution in cm3 Dp = Differential pressure in bar n = Speed in rpm nv = Volumetric efficiency nmh = Mechanical-hydraulic efficiency nt = Total efficiency (nt = nv...
