BR-E85N (previously SLBM-E) bellow components have similar installation sizes as Eagle Burgmann MFL85N metal bellow components.
It is designed for unstepped shafts, working under high temperature and moderate pressure operating conditions in oil / gas industries or petro-chemical / chemical processing. Flexible graphite is used as the secondary seal. When the space is limited it can operate against shorter stationary seat.
