Eaton Vickers MFB motor
Eaton Vickers inline motor MFB5, MFB10, MFB20, MFB29, MFB45
Operating pressure up to 210 bar (3000 psi)
Displacement from 10,5 to 94,4 cm3/r (0.64 to 5,76 in3/r)
Speed up to 1800 r/min
Vickers fixed displacement inline piston motors offer a choice of five torque ratings. Reversible shaft rotation and flange or foot mountings are available.
Vickers MFB hydraulic motor is of axial piston, fixed displacement, inline design. The units can be operated in either direction of rotation. Flow direction is as indicated. MFB motors are variable horsepower – horsepower being approximately proportional to rpm with a given constant operating pressure. Service may be continuous, intermittent, continuous reversing, or stalled without damage when properly protected by a relief valve. Output speeds are dependent on input flow. Speed ranges of at least 36:1 are possible at the maximum torque rating by varying flow to the motor.

Vickers MFB piston motor is designed to meet the specifications shown in the “Ratings” section of this catalog. To ensure maximum performance in conjunction with your specific application, consult your Vickers sales representative if your:
Pressure requirements are above 100 bar (1500 psi).
Speed is above 1800 r/min rating. Speed is below minimum recommended speed of 100 r/min.
System requires fire resistant or other fluids. Operating temperature is not within the range of 38 to 66 C (100 to 150 F). With proper application and fluid consideration, a greater temperature range is permissible. Oil viscosities at operating conditions is not within 100 to 250 SUS. Application requires an indirect drive. Oil viscosity at start-up is in excess of 1000 SUS. Mounting attitude is other than horizontal.
Overall operating efficiency can be as high as 93% and volumetric efficiency as high as 97%, depending on motor size, pressure, speed, fluid viscosity, and temperature.
Compact, High Performance
High speeds, pressures and efficiencies give Vickers inline piston motors power density. The result is high performance in a compact package that requires minimum installation space.
Low Speed Capability: Minimum speed can vary between 50 and 100 r/min, depending upon motor size and characteristics of the drive load.
Reliability: Vickers inline design has seen countless hours of rugged service on a variety of machinery applications. This proven design has provided significant cost and weight savings, while taking full advantage of the high efficiency inherent in piston units.
