4 4/36 osch Rexroth Corp. 2FM R 91001/03.08 Technical Data Hydraulic fluid efore starting project planning, please refer to our data sheets RE (mineral oil), RE (environmentally acceptable hydraulic fluids) and RE (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions. The fixed motor 2FM is unsuitable for operation with HF. If HF, HFC and HFD or environmentally acceptable hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE and RE must be observed. When ordering please indicate the used hydraulic fluid. Operationg viscosity range For optimum efficiency and service life, select an operating viscosity (at operating temperature) within the optimum range of ν opt = optimum viscosity SUS ( mm 2 /s) depending on the circuit temperature (closed circuit) and tank temperature (open circuit). Limits of viscosity range The limiting values for viscosity are as follows: Sizes 5 to 200: ν min = 42 SUS (5 mm 2 /s) short-term (t < 3 min) at max. permitted temperature of t max = +240 F (+115 C). ν max = 7400 SUS (1600 mm 2 /s), short-term (t < 3 min) at cold start (p 435 psi / 30 bar, n 1000 rpm, t min = -40 F / -40 C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes. Sizes 250 to 1000: ν min = 60 SUS (10 mm 2 /s), short-term (t < 3 min) at max. permitted temperature of t max = +195 F (+90 C) ν max = 4600 SUS (1000 mm2/s), short-term (t < 3 min) at cold start (p 435 psi / 30 bar, n 1000 rpm, t min = -13 F / -25 C). Only for starting up without load. Optimum operating viscosity must be reached within approx. 15 minutes. Note that the maximum hydraulic fluid temperature of +240 F (115 C) (+195 F (+90 C) at size 250 to 1000) must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 22 F (12 K) higher than the average case drain temperature. Special measures are necessary in the temperature range from -40 F and -13 F (-40 C and -25 C) (cold start phase), please contact us. For detailed information about use at low temperatures, see RE Selection diagram viscosity ν SUS (mm2/s) (1600) (1000) (600) (400) (200) (100) (60) (40) (20) (10) (-40 ) (-20 ) (0 ) (20 ) (40 ) (60 ) (80 ) (100 ) VG 22 VG 32 VG 68 VG 46 VG (1600) 170 (36) νopt. 80 (16) (5) 42 (5) (-40 ) (-25 ) (-10 ) (0 ) (10 ) (30 ) (50 ) (70 ) (90 ) (115 ) t min = -40 F (-40 C) fluid temperature range t in F ( C) Details regarding the choice of hydraulic fluid t max = +240 F (+115 C) The correct choice of hydraulic fluid requires knowledge of the operating temperature in relation to the ambient temperature: in a closed circuit the circuit temperature, in an open circuit the tank temperature. The hydraulic fluid should be chosen so that the operating viscosity in the operating temperature range is within the optimum range (ν opt. ) - the shaded area of the selection diagram. We recommended that the higher viscosity class be selected in each case. Example: t an ambient temperature of X F (X C) an operating temperature of 140 F (60 C) is set. In the optimum operating viscosity range (ν opt ; shaded area) this corresponds to the viscosity classes VG 46 or VG 68; to be selected: VG 68. Please note: The case drain temperature, which is affected by pressure and speed, is always higher than the control temperature or tank temperature. t no point in the system may the temperature be higher than 240 F (115 C) for sizes 5 to 200 or 195 F (90 C) for sizes 250 to If the above conditions cannot be maintained due to extreme operating parameters, we recommend flushing the case at port U (size 250 to 1000) or using a flush and boost pressure valve (see page 30). Filtration The finer the filtration, the higher the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit. To ensure functional reliability of the axial piston unit, the hydraulic fluid must have a cleanliness level of at least 20/18/15 according to ISO t very high hydraulic fluid temperatures (90 C to max. 115 C, not permitted for sizes 250 to 1000) at least cleanliness level 19/17/14 according to ISO 4406 is required. If the above classes cannot be observed, please contact us.

6 6/36 osch Rexroth Corp. 2FM R 91001/03.08 Technical Data Shaft seal ring Permissible pressure loading The service life of the shaft seal ring is affected by the speed of the motor and the case drain pressure. It is recommended that the average, continuous case drain pressure at operating temperature 45 psi (3 bar) absolute not be exceeded (max. permissible case drain pressure 90 psi (6 bar) absolute at reduced speed, see diagram). Short-term (t < 0.1 s) pressure spikes of up to 145 psi (10 bar) absolute are permitted. The service life of the shaft seal ring decreases with an increase in the frequency of pressure spikes. The case pressure must be equal to or greater than the external pressure on the shaft seal ring.

30 30/36 osch Rexroth Corp. 2FM R 91001/03.08 Flush and oost Pressure Valve The flush and boost pressure valve is used to remove heat from the closed control and to ensure that a minimum boost pressure is present (opening pressure 230 psi (16 bar), fixed; note when setting primary valve). side effect is flushing of the case. Warm hydraulic fluid is directed from the respective low pressure side into the motor case. This is then fed into the tank, together with the case drain. The hydraulic fluid drawn out of the closed control in this way must be replaced by cooled hydraulic fluid that is supplied by the boost pump. In an open control system, the flush and boost pressure valve is used solely to flush the case from the return line. On port plate 527, the valve is fitted directly onto the fixed motor (size 45 to 180, 250), while on port plate 017 (size 355 and 500), it is fitted on a plate. Orifice can be used to adjust the flushing volumes as required. Standard flushing volumes (at low pressure Δp LP = 365 psi / 25 bar) Size Flushing flow Mat.-no-orifice 45, 56, gpm (3.5 L/min) R , gpm (5 L/min) R , gpm (8 L/min) R , gpm (10 L/min) R gpm (10 L/min) on request 355, gpm (16 L/min) on request For sizes 45 to 180, orifices for flushing volumes of gpm ( L/min) can be supplied. In the case of non-standard flushing volumes, please specify the desired flushing volume when ordering. The flushing volume without orifice is approx. 3.2 to 3.7 gpm (12 to 14 L) at low pressure Δp LP = 365 psi (25 bar).

31 R 91001/ FM osch Rexroth Corp. 31/36 Pressure Relief Valves The pressure relief valves MHD (as to RE 64642) protect the motor from excess pressure. When the set opening pressure is reached the hydraulic fluid flows from the high pressure side to the low pressure side. The pressure relief valves can only be supplied in conjunction with the port plates 181, 191 or 192 (counterbalance valve for fitting on port plate 181, see next page). Setting range opening pressure psi ( bar) t design "with pressure sequence range" (192) a higher pressure setting can be realized by applying an external pilot pressure of psi (25-30 bar) at port P St. Please indicate in clear text when ordering: opening pressure of the pressure relief valve opening pressure at pilot pressure applied at P St (for design 192 only) Design without pressure sequence range "191" T 1 M Unit dimensions D9 T 2 D10 D12 D1 D2 D5 D11 D13 T 1 M efore finalizing your design, please request a D3 D7 D6 S 1 only for port plate "181" Detail Z: Design without pressure sequence range "191" or "181" D8 Z M S 1 M Detail Z: Design with pressure sequence range "192" D8 D4 D6 T 2 M S 1 Design with pressure sequence range "192" T 1 M P St T 2 M P St S 1 M Ports, Service line ports SE J518 S 1 oosting (only for port plate 191/192) M, M Gauge ports (plugged) P St Pilot pressure port (only for port plate 192) S 1 M Size, 1 ) S 2 1 ) M, M p 3 St ) 28, 32 SE 3/4 in M22x1,5; M20x1,5; G 1/ (14) deep 0.55 (14) deep 2 ) 45 SE 3/4 in M22x1,5; M20x1,5; G 1/ (14) deep 0.55 (14) deep 2 ) 56, 63 SE 3/4 in M26x1,5; 0.63 (16) deep M26x1,5; 0.63 (16) deep 2 ) G 1/4 80, 90 SE 1 in M26x1,5; 0.63 (16) deep M26x1,5; 0.63 (16) deep 2 ) G 1/4 107, 125 SE 1 / 4 in M26x1,5; M26x1,5; G 1/ (16) deep 0.63 (16) deep 2 ) 160, 180 SE 1 / 4 in M26x1,5; 0.63 (16) deep M30x1,5; 0.63 (16) deep G 1/4 1 ) SE J518 2 ) DIN ) DIN ISO 228 Size D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 4 ) 28, 32 MHD.16 in M10; 0.67 deep mm deep 45 MHD.16 in M10; 0.67 deep mm deep 56, 63 MHD.22 in M10; 0.51 deep mm deep 80, 90 MHD.22 in M12; 0.71 deep mm deep 107, 125 MHD.32 in M14; 0.75 deep mm deep 160, 180 MHD.32 in M14; 0.75 deep mm deep 4 ) DIN 13, please observe the general notes for the max. tightening torques on page 36 ssembly instructions for port plate with pressure sequence range 192 : When fitting the hydraulic line on the P St port, the lock nut must be held in place!
