Structural Features: single end, unbalanced, independent direction of rotation, rubber bellow transmission. This component has a compact structure and it is easy to install. The bellow and the spring provide pressure compensation to the seal faces. The rubber bellow design prevents possible radial run-out so the floatabilitiy of the rotary ring is increased.<\/td>\n<\/tr>\n
