practices make Sayog actuators most reliable actuating force for latest GEAR DRIVE
control systems. Well lubricated, robust gear drive is heart of SAYOG actuator. Ground worm gear
is used for regulating duty for long life. Well supported and lubricated bearings
Sayog actuators are suitable for a variety of switchgear and control signal are used for extended trouble free service.
systems. At Sayog, we endeavor to provide optimum solutions to wide HANDWHEEL OPERATION
ranging requirements of actuations. CA range of actuators are provided with hand wheel facility for manual operation in the event of power
failure. In CA-range unique exclusive motor/manual mode clutch safeguards the operator against
injury.
Sayog actuators are indigenously developed since 1984. Simple modular design makes the

actuator easy to handle and maintain. Variety of thrust adaptors, couplings and add-on gear
Two easily settable cam operated Micro Switches are provided, one each for OPEN and CLOSE
boxes combine with the actuator to obtain almost all types of movements.
Travel limitation. Simple, economical gear train is used for cam operation. Sayog mechanism does not
employ any springs to avoid malfunctioning of the limit switch due to corroded / slack springs.
Use of High quality materials ensures maximum reliability. Sayog actuators are suitable for

outdoor installations and are suitable for wide range of temperature from -20°c to +50°c. Special
Two reliable torque limit switches protect the driven equipment against excessive torque. Torque
enclosures to IP-68 are available for more severe weather conditions.
switches are precisely set at values specified. However the Torque setting can be adjusted at site by
using the calibrated dial.
