General Purpose Rotary Unions
Duff-Norton, USA, offers its Series 9000 general purpose rotary unions in sizes from 1/4"to 5". They feature a bellowstype seal to provide greater flexibility where equipment misalignment is inherent, and to resist seal hang-up in media contaminated with debris and suspensions. All sizes over 1-1/4"have dual bearings for additional load support. The Series 9000 is available with either flanged or threaded shaft connections for greater mounting flexibility.
