WSD universal coupling features:

Each section has a maximum rotation angle of 45 °

Connect a larger shaft pitch

    Finished hole tolerance for the H7, and the other according to the requirements, open keyway, square hole, hexagonal hole

    Allowing the angle between the two axes to vary within the defined range as the work needs

WSD universal coupling material: WSD cross shaft with alloy steel (40Cr, 40CrNi, 20CrMo, 20CrMnVB) manufacturing, heat treatment after the hardness of 58 ~ 62HRC, other parts are made of 35 or 45 steel and heat treatment 48 ~ 52 HRC.

    WSD universal coupling at both ends of the connection form: the same ends with the same hole shape, with cylindrical holes, with key groove cylindrical hole, square hole; both ends with different hole shape, with cylindrical hole with a key slot cylindrical hole, Cylindrical hole with square hole, with key groove cylindrical hole and with four square holes.
