SGM7A Gear Motors
The SGM7A gear motor product family pairs SGM7A servo motors with high precision, low backlash inline
planetary gear heads resulting in a portfolio of rotary actuators fit for a wide range of applications. The fam
‐
ily of gear motors has been thoroughly tested and adheres to the high levels of quality and performance
expected from Yaskawa.
Model Designations
The high precision gear heads offer a variety of application advantages:
• 
Quiet operation – helical cut gears contribute toward reduced
vibration and noise
•

High precision – a standard backlash of 5 arc-min make this gear
head ideal for the most accurate applications
• 
High rigidity and torque capacity – achieved with a design
which incorporates uncaged needle roller bearings
•

Optimized adapter bushing – minimizes inertia allowing for more
output torque to be realized
• 
No leakage through the seal – high viscosity, anti-separation
grease does not liquefy and does not migrate away from the gears
• Maintenance-free – no need to replace the grease for the life of the
unit. The reducer can be positioned in any orientation
