On the stern tube sealing, it has been required the longer durability as one of the sealing performance in order to sail without any trouble for the long time. It is understood the temperature at the contact of sealing ring and liner is mostly affected to the durability of this type of sealing system. Then, keeping an eye on the above temperatures, the authors have theoretically analysed and estimated the temperature at the contact as accurately as possible based on the measured data.<BR>As a result, the influences of circumferential velocity of the liner and differential pressure to the temperature at the contact of sealing ring and liner were made clear quantitatively.<BR>Furthermore the charts of permissible endurance limit on sealing ring were made based on the above results, and this has become valuable when the service condition of the stern tube sealing (Compact Seal) has been determined.
