Duff-Norton 9000G Series
High Temperature
Rotary Unions ®
The unique design of the bellows type
Rotary Union ® permits them to be used to
introduce heating agents into rolls or cylinders
in various types of machinery. The Series
9000G offers the same design as the
standard 9000 Series (page 14), but utilizes a
carbon graphite bearing for high temperature
applications. Because there is no rolling
element bearing, no lubrication is required,
making the 9000G maintenance free. The
9000G thrust collar allows for thermal
expansion, making this an ideal union for high
temperature general purpose applications.
