The FCG-AJ series strain wave gear is engineered for high-torque and heavy-load applications. It adopts a cup-style flexspline and an integrated cam wave generator, where the cam shaft bore can be customized to match specific motor models. The input shaft directly interfaces with the wave generator's inner bore via a keyway connection. This series typically employs a fixed circular spline end and an output flexspline end configuration.

The FHG-II series strain wave drive features a cross roller bearing coupling structure for its wave generator, allowing for automatic fine-tuning of coaxiality. The size of the cam shaft hole can be adjusted according to the customer's motor model, with the input shaft directly fitting into the inner bore of the wave generator and connected via a flat key. It incorporates a built-in high-rigidity cross roller bearing (main bearing). Generally, it is used with the rigid wheel end fixed and the flexspline end output, or with the flexspline fixed and the rigid wheel end output as the connection method.

The FSG-I series Strain wave gear employs an integrated cam-type wave generator. The cam shaft bore dimensions can be customized to match customer-specific motor models. The input shaft directly interfaces with the wave generator's inner bore via a keyed connection. This system is typically configured with the circular spline fixed at the base and the flexspline functioning as the output end.
