HIGH SPEED MOTORS
 These motors offer the high speeds previously only associated with axial
piston designs, and therefore the corresponding high powers. High running speeds of up to 2500 RPM and 2800 RPM freewheeling are possible with the smaller displacement motors. High-pressure versions
are also available with peak pressure capability of 800 bar.

WHEEL DRIVE UNITS
 SAI offer both direct wheel drive units with or without automotive style drum
brakes and combined motor/gearboxes with or without spring applied hydraulic pressure released brakes. These are ideally suited for a wide range of mobile applications, and displacements range from 60 cc/rev
through to 4111 cc/rev.

GEARBOXES AND BRAKES
A range of single stage epicyclic gearboxes is available enabling high torque to be achieved with compact dimensions. Spring applied, hydraulic pressure released brakes can also be
incorporated into these units. SAI motors can also be easily fitted on to many proprietary gearboxes and SAI(GB) Ltd. can supply these as a package if required.
WINCHES
 SAI have a range of standard winches from 800 kg to 3 tonnes line pull,
with each unit including hydraulic motor, drum, mounting bracket, single overcentre valve and fail safe brake.

VALVES
SAI(GB) Ltd. can offer a range of cartridge type valves either fitted directly into the motor distributor or in a separate block which can be mounted directly onto a standard distributor or
in line for higher flow rates. The valves available include cross line relief valves, overcentre valves, brake shuttle valves, purge valves and anti cavitation valves.
