This standard specifies the type, basic parameters, dimensions, technical requirements, inspection rules and marking, packaging and storage requirements of spherical roller couplings for drums. This standard is applicable to the couplings of the reducer and drum of the lifting mechanism and other similar mechanisms, used for transmitting torque and supporting radial loads. The working temperature is -25~80℃; the nominal torque transmitted is 4~800kN·m; the permissible radial force is 14.5~450kN.
