5 When using HF- or environmentally acceptable fluids attention must be paid to possible limitations of the technical data, if necessary contact us (when ordering, please state in clear text the fluid to be used). Operation on Skydrol fluid is only possible after consultation with viscosity rangeFor optimum efficiency and service life we recommend that the operating viscosity (at operating temperature) be selected in the range opt = opt. operating viscosity SUS ( mm2/s)referred to tank temperature (open circuit).Limit of viscosity rangeFor critical operating conditions the following values apply: m n = 60 SUS (10 mm2/s) for short periods (t 1 min) at max. perm. fluid temperature of 239 F (115 C).Please note that the max. leakage fluid temperature of 239 F (115 C) is also not exceeded in certain areas (for instance bearing area). The fluid temperature in the bearing area is approx. 7 F (5 K) higher than the average leakage fluid tem-perature. max = 7500 SUS (1600 mm2/s) for short periods (t 1 min) on cold start p 435 psi (30 bar), n 1500 rpm, tm n = -13 F (-25 C)At temperatures between -40 F (-40 C) and -13 F (-25 C) special measures are required, please consult us for further detailed information on operation with low temperatures see data sheet RE diagramNotes on the selection of the hydraulic fluidIn order to select the correct fluid, it is necessary to know the operating temperature in the tank (open circuit) in relation to the ambient fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range ( opt), see shaded section of the selection diagram.

6 We recom-mend to select the higher viscosity grade in each : at an ambient temperature of X F (X C) the opera-ting temperature in the tank is 140 F (60 C). In the optimum viscosity range ( opt; shaded area) this corresponds to viscosi-ty grades VG 46 resp. VG 68; VG 68 should be : The leakage oil (case drain oil) temperature is influ-enced by pressure and input speed and is always higher than the tank temperature. However, at no point in the circuit may the temperature exceed 239 F (115 C).If it is not possible to comply with the above conditions becau-se of extreme operating parameters or high ambient temperatu-res please consult of fluidThe finer the filtration the better the achieved cleanliness of the pressure fluid and the longer the life of the Axial Piston ensure a reliable functioning of the Axial Piston unit, a mini-mum cleanliness of 20/18/15 to ISO 4406 is very high temperatures of hydraulic fluid (195 F (90 C) up to max. 239 F (115 C)) at least cleanliness of 19/17/14 to ISO 4406 is above cleanliness level cannot be met please consult fluids RA 92 703 | A10VO Bosch Rexroth Corporation 5/36 Operating pressure range InletAbsolute pressure at port S pabs m n _____12 psi ( bar)pabs max _____73 psi (5 bar)To determine the min.
