Stern Shaft Bearing With Flange
Bronze rubber bearing, bronze rubber bush for water lubricant for marine industry. Naval brass rubber bush adapt equally well to strut and stern tube mounts. And are often used effectively as rudder-stock and pintle bushings. Bearing diameters are precision fitted to the designated shaft size with the correct clearance for efficent water lubrication.
External brass shells are machined and polished to provide easy fitting. Specially formulated oil and chemical resistant ntrile rubber is securely bonded to the shell. Unit with thin shells are available for the struts of small craft. Sleeve bearings are usually installed by light press-fitting and locked in place with once pointed set screws

Have Incomparable performance under a high load, low speed operation. Also perform well without lubrication,
Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations
Remarkable resistance to corrosion and resistance to chemical attack
Maintenance free and save operating cost.
Water-lubricated copper sleeve rubber bearings than the general hard surface rubber bearing life expectancy of more than 10 times oil and chemical products, operating temperature of 4-71 degrees Celsius (39f-158f), applicable speed range: 5-7500 rpm/min, friction coefficient: high speed when less than 0.02, low speed (less than 30 rpm/ min) The maximum friction coefficient is less than 0.09. Rubber hardness: hs70±5, Aging coefficient (90℃*24h) is not less than 0.75, wear (a clone) is not less than (cm3/1.61km) 0.40, the outer copper sleeve with seawater corrosion of the Navy brass (another stainless steel sets, aluminum sets, composite fiber sets optional)
