SAI Motori Idraulici SpA

The B series five cylinder crankshaft design radial piston hydraulic motor utilises many of the proven components from the GM series motors, well known for their high performance and reliability. The innovative design of the new sliding central bearing arrangement, made possible by the latest materials and manufacturing techniques increases the range of possible options in SAI hydraulic motors. These include the possibility to change displacement, fit taper roller barings for axial load capability, have a hollow through shaft option, and fit a counterbalance weight to smooth out high speed vibration. It's also possible to accept higher radial loading of the motor shaft due to a larger cross section giving extra strenght.
