roller bearings; such as ball bearings and tapered roller bearings; or non-roller bearings, like graphite bearings and bronze brushings, may be used in a rotary union. the bearings are always used to allow a part of the joint, either the shaft or the housing, to rotate mechanical seal. the heart of the rotary union is the seal.
