S SERIES HELICAL-WORM GEAR REDUCER
1. S series reducer are based on the building block design, so it's convenient for them to fit all types of
motors or to connect with other power input. The same type of combine can fit motors with different
power, so that it's possible for different types of machines to combine or connect.
2. S series column worm speed reducer is a combination of oblique gear and worm gear stages, whose
maximum stand-alone efficiency can reach up to 89%.
3. Precise division of transmission ratio with a wide range. The combination of machines can produce
a larger transmission ratio at a low output rotational speed.
4. Various ways of installation. Foot-mounted,B5 flange-mounted or B14 flange-mounted. Foot-mounted
reducer has two machine foot-mounted planes, hollow shaft-mounted style except 37 serve two
parameter for customer select.

Instructions for Selection:
The total factor fA of helical-worm reducer should meet the following formula:
fA=fAL fA1 fA2
fAL Load charactristic and daily operating time factor
fA1 Service factor from the ambient temperature
fA2 service factor from the cyclic duration factor
1. Model S
Foot-mounted helical-worm gear reducer
2. Model SF
B5 flange-mounted helical-worm gear reducer
3. Model SAF
B5 flange-mounted helical-worm gear reducer with hollow shaft
4. Model SA

The total operating mode factor (fA) should meet the following formula: Service factor fB operating mode factor fAThe service factor fB is listed in the parameter selection list.
The permitted overhung loads and the axial forces.
Plese contact our technical supporting department for the information on the permitted overhung loads and the axial forces
at the output end of the shaft.
Regarding the use and maintenance of the reducer, please refer to the attached lnstruction Manual of the Reducer and the
Variable Speed Motor.
