SAI are world leaders in the manufacture of high torque hydraulic motors with their crankshaft design radial piston motors.
Some of the main advantages and characteristics of these motors are:
* Capable of High Speeds
Due to larger oil ducts for higher flow capability and are counter balanced to reduce vibrations at speed.
* High Pressure Capability
Due to the thick steel walled cylinders SAI is able to produce motors capable of up to 800bar, the cylinder is separated from the motor body and there is no internal mechanism to the piston which allows SAI to reduce the piston diameter. All this also allows the motor to accept high pressure simultaneously on the input and output ports.
* Cavitation Resistance
The SAI design enables the motor to run without oil or in full cavitation, ensuring the motor can run non stop at maximum speed. Please also note the roller bearing under the pistons does not require lubrication under pressure.
A number of features distinguish SAI motors from other radial piston designs:
* swivelling cylinder;
* double piston support bearing;
* piston retaining rings;
* rotary axial distributor;
* interchangeable distributor;
* high starting torque
SAI has a complete range of motors including:
* wheel units;
* crankshaft design radial piston hydraulic motors;
* high speed motors;
* double shaft motors;
