The Sternguard OLS is an oil lubricated outboard (OLS3-P and OLS4-P) and inboard (OLS2-P) lip sealing solution which can be suited to many applications including merchant, cruise and ferry, offshore, inland water way (IWW) and thrusters. This seal is a conventional solution for these applications due to its high wear resistant seal rings and liner. The seal rings are made of Viton® rubber, a durable and long-lasting material tested to withstand turbulent weather conditions. The liner provides a running surface
for the seal rings and protects the propeller shaft from wear. This solution is provided as a partially split offering but is also available as fully-split, with the possibility to perform retrofits without removing any shaft line components.
