Bosch Rexroth Fixed displacement motor A4FM

Features
– Axial piston fixed displacement motors A4FM in swash plate design are used for hydrostatic transmission in open and closed circuits.
– Output speed is proportional to the input flow and inversely proportional to the motor displacement.
– Output torque increases with the pressure difference between high-pressure and low-pressure sides.
– Long service life, optimum efficiency
– Compact design for special applications where the A2FM is not suitable
– Proven rotating assembly with swash plate technology

Hydraulic fluids
Before you start project planning, please refer to our technical data sheets RC 90220
(mineral oils), RC 90221 (environmentally friendly hydraulic fluids) and RC 90223
(HF fire-resistant hydraulic fluids) for detailed information on the selection of operating fluids and application conditions.
When using HF or environmentally friendly hydraulic fluids, the possible limitations of the technical data should be taken into account. If necessary, please consult our technical department (please specify the type of hydraulic fluid used in your application in the order form).
Sizes 22..56 are not suitable for use with HFA, HFB and HFC.

Safety Instructions
When starting and during operation, the motor housing must be filled with hydraulic oil (into the housing cavity). The motor must be started at low speed and without load until the system is completely drained.
During long periods of storage, the housing can be drained through the working line. When restarting, ensure that sufficient oil is filled into the housing.
Leaking oil in the housing must be drained into the oil tank through the housing drain port in the highest position.
