There are certain cases where it is necessary to make sure that two machines have a considerable amount of parallel radial offset. Such machines are usually coupled by a Heavy Duty SWC-BF Type Cardan Shaft where more than 4-6 degrees of angle exists between the cardan coupling and the machines. Once the offset is established, it is important to ensure the machines are parallel to each other. If angular misalignment exists (i.e. the machines are not exactly parallel to each other) a rapid change in the shaft RPM will result during operation, as well as an uneven bearing loading, which could shorten the life of the machine. A special cardan bracket was developed specifically for this application. Cardan Shaft for Rolling Mill is main function is to directly translate the axis of rotation of one machine to the axis of rotation of the other machine.
