Hollow shaft is connected by a threaded or hydraulic flange onto the roller or rollers, as the main rotating parts, and equipment for the synchronous movement. Double seal ring with hollow shaft and bellows sealed together to form a floating friction, help reduce due to the large, heavy equipment brought seal concentricity bad and other shortcomings. Seal ring by a maceration of carbon graphite, have good self-lubricating properties, reducing friction and wear, improve the life; after the seal ring wear by means of a spring bellows pressure compensated at any time. Bearings using one hand to play a supportive role, but also enhance the rotating
accuracy and reduce the friction torque. In addition, with observation hole on the housing, by observing the hole may be observed at any time to wear and seal the sealing ring.
