Environmental Resistance
Stainless steel is used for the case body and output shaft to achieve high rust/corrosion resistance
Quiet Operation
The high-precision helical planetary gear provides a smooth mesh that maintains even load balancing for quiet operation.
High Efficiency & Compact
The helical planetary gear mechanism delivers high efficiency. The ring gear is machined integrally to the housing, allowing for a more compact design.
Low Backlash
High level gear cutting technology achieves low backlash
Mount Code
Standard line of flanges compatible with servomotors from various manufacturers
