    • The dimensions marked with an asterisk (*) refer to the axial connection positions of the three components (wave generator, flex wheel, and rigid wheel) and the allowable tolerances. These dimensions will affect performance and strength, so they must be strictly followed.

    • Due to different manufacturing methods (casting, machining) of components, tolerances may vary. For dimensions not specified with tolerances, please consult our company or authorized agents for tolerance ranges.

    • Since the flex wheel will undergo elastic deformation, to prevent it from contacting the housing, please use an inner wall dimension larger than Ф a.b.c and smaller than d.

    • The wave generator is packaged separately upon product delivery.

    • Dimensions marked with the # symbol can be customized according to the customer's needs. Please consult our company or authorized agents for specific dimensions.
