The YHS - IV series flexible wheel is a hollow flanged standard structure, and the wave generator cam comes with an input shaft. The inside of the reducer is supported by deep groove ball bearings at both ends, with a fully sealed structure and easy installation. It is very suitable for scenarios where bevel gears or synchronous belt drives need to be installed at the input end.

The YHS - III series flexible wheel is a hollow flanged standard structure, and the wave generator is a large-diameter hollow shaft. The inside of the reducer is supported by deep groove ball bearings at both ends, with a fully sealed structure and easy installation, making it very suitable for situations where wires need to be threaded from the center of the reducer.

The YHS II series flexible wheel is a hollow flanged standard structure, with a compact overall mechanism. The input shaft is matched with the inner hole of the wave generator through a cross slider shaft coupling and connected through a flat key. It can be connected either by fixing at the rigid wheel end and outputting at the flexible wheel end, or fixing at the flexible wheel end and outputting at the rigid wheel end

The YHS - I series flexible wheel is a hollow flanged standard structure, with a compact mechanism. The input shaft is directly matched with the inner hole of the wave generator and connected through a flat key. It can be connected either by fixing at the rigid wheel end and outputting at the flexible wheel end, or fixing at the flexible wheel end and outputting at the rigid wheel end
