EVR KEMEL Stern tube
Combination of Advantages of Reinforced Plastic with Those of Elastomer
The outer shell is made of reinforced plastic formed with glass cloth and cotton cloth, and the sliding face is made of elastomer.
Therefore, it is of high adhesive property, excellent corrosion resistance and light weight.
Outstanding Durability os shaft vibration
Shaft load is balanced by high elasticity of rubber and increased coverage area to avoid concentrated load in the aft end.
Effective Absortion of shaft vibration
With the unique features of rubber, the EVR absorbs shaft vibtration and prevents premature wear down of components.
Prevention of Electronyc corrosion on the Shaft Sleeve
Since the construction materials are non conducting, EVR bearing cuts the corrosive electric current from the shaft sleeve and prevents the shaft sleeve surface from gettin rough.
Straight Type Bearing
The outer shell is made of cotton reinforced Plastic (CPR) which is impregnated by thermosetting resign. It is suitable to be installed in ships with relatively small diameters.
Flange Type Bearing
The outer shell is made of Glass Cloth reinforced Plastic (GPR), and is suitable for relatively larger diameter.
Cooling water is required for prevention of aging and fatigue on the bearing due to heat build up. During the shaft rotation, it is recommended to cool the bearing to the normal temperature. Do not rotate the shaft without supplying water.
