Strain wave gear reducer FCG series

coaxialkeyed shaft1000 - 5000 Nm

Introduction
The FCG-AJ series strain wave gear is designed for high-torque and heavy-load industrial applications. It uses a cup-style flexspline and an integrated cam wave generator; the cam shaft bore can be customized to fit specific motor models. The input shaft connects directly to the wave generator inner bore via a keyway. The series is typically configured with a fixed circular spline at one end and an output flexspline at the other end.

Features

• High torque capacity and improved load-bearing performance
• Integrated cam wave generator simplifies installation and supports multiple mounting options
• High rotational accuracy and repeatable positioning
• Coaxial input/output alignment for compact system integration
• Suitable for machinery requiring specialized torque and heavy-load handling
