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 90220 (mineral oil), RE 90221 (environmentally acceptable hydraulic fluids) and RE 90223 (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 90221 and RE 90223 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 80...170 SUS (16...36 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 90300-03-.

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 1000. 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 4406. 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.

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.

34/36 osch Rexroth Corp. 2FM R 91001/03.08 Speed Measurement The 2FM...D and 2FM...F ("prepared for speed measurement", i.e. without sensor) versions have teeth on the rotary group. The rotating, toothed rotary group generates a signal in proportion to the speed. The signal is picked up by a sensor and can be forwarded for evaluation. The sensor is fitted to the special port D provided for this purpose. The following versions are available: Version D (sizes 23 to180) Suitable for mounting the inductive speed sensor ID (see R 95130). The ID sensor is screwed into port D. The spacer ring adapter required for the inductive speed sensor ID is included in the supply volume of the sensor (only when ordering, speed sensor with installation parts). Version F (sizes 23 to 250) Suitable for mounting of HDD Hall effect speed sensor (see RE 95135). The HDD sensor is flange mounted with two fastening screws.

R 91001/03.08 2FM osch Rexroth Corp. 35/36 Installation Notes General The motor case must be completely filled up with hydraulic fluid during startup and during operation (filling the case chamber). The motor must be started at low speed and no load until the system has been bled completely. If stopped for an extended period, fluid may drain out of the case through the working lines. When restarting, make sure that the case contains sufficient fluid. The leakage fluid inside the case chamber must be drained off to the tank through the highest case drain port. Installation position Optional. t size 10 to 200 with installation position shaft to the top use motor with bleeding port R (indicate in clear when ordering; the port U in the bearing section for bleeding is included in production with sizes 250 to 1000). Installation below tank level Motors below minimum fluid level in the tank (standard) Fill axial piston motor before startup via the highest case drain port Run the motor at low speed until the system is bled completely (bleed through service line port, if tubing is long) Minimum immersion depth of leakage line in tank: 7.87 in (200 mm) (relative to the min. fluid level in the tank) dditional measures required for installation position 2 (shaft facing up): with installation position 2, make sure that the motor case is completely full before starting up. leed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text. n air pocket in the bearing area can cause damage to the motor. Installation above the tank Motor above minimum fluid level in tank Proceed in same way as below the tank installation dditional measures for installation positions 1 and 2: If stopped for an extended period, fluid may drain out of the case chamber through the service lines (air enters through the shaft seal). The bearings will therefore not be properly lubricated when the motor is started up again. Fill the axial piston motor before restarting via the highest case drain port. Installation position 2: bleed at port R (sizes 10 to 200) resp. U (sizes 250 to 1000). Order port R in clear text. dditional measures required for installation position 2 (shaft facing up) In this installation position the bearings will not be properly lubricated, even if there is still some fluid in the case chamber. Putting a non-return valve (opening pressure 7.5 psi (0.5 bar)) in the leakage line can prevent the system emptying through the line.

36/36 osch Rexroth Corp. 2FM R 91001/03.08 General Notes The 2FM motor is designed to be used in open and closed circuits. Project planning, assembly, and commissioning of the motor require the involvement of qualified personnel. The service line ports and function ports are only designed to accommodate hydraulic lines. During and shortly after operation, there is a risk of burns on the motor. Take suitable safety precautions, e.g. wear protective clothing There may be shifts in the characteristic depending on the operating state of the motor (operating pressure, fluid temperature). Tightening torques: - The tightening torques specified in this data sheet are maximum values and must not be exceeded (maximum values for screw thread). Manufacturer's instruction for the max. permissible tightening torques of the used fittings must be observed! - For ISO 68 / DIN 13 fixing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003. The data and information contained herein must be adhered to. osch Rexroth Corporation Hydraulics xial & Radial Piston Units 8 Southchase Court Fountain Inn, SC 29644-9018, US Telephone (864) 967-2777 Facsimile (864) 967-8900 www.boschrexroth-us.com 2007 osch Rexroth Corporation ll rights reserved.
