Features: Shrink disc is an advanced basic component for mechanical coupling under heavy loads. In the connection of the wheel and the shaft, it is a kind of keyless coupling device that achieves load transmission by tightening the high-strength bolts to generate pressure and friction between the conveying surfaces. Suitable for high load applications. Especially applicable for alternating torques. Typical applications: flywheels, belt drums.
