SB - Intramark

Fémházas rugós szimering

SB is a single action rotary shaft seal for rotating. The SB model has limited sealing action with thin fluid or gaseous media and with split housings. To guarantee a high degee of static sealing on the outer surface, better surface treatment of the housing bore is required or an additional coat of paint should be applied to the outer surface.
