| The unique design of the
bellows type Rotary Unions®
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, 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.
