This water-lubricated propeller shaft bearing with rubber lining and cylindrical resin outer shell is intended for marine shaft lines and inboard systems. The bearing supports and guides the rotating propeller shaft, while water acts as a lubricant during operation instead of grease or oil.
The bearing surface is made of water-lubricated rubber, and the outer shell is made of resin or synthetic resin. The design is particularly suitable for aluminum hulls with aluminum shaft struts or bearing housings. The bearing has no documented external metal shell, and no tolerances or specific method of attachment are specified.
Choose the variant that fits the propeller shaft and the bore of the bearing housing. Dimensions are given as inner diameter × outer diameter × length: 25 × 38.10 × 100 mm (1 1/2"), 30 × 44.45 × 120 mm (1 3/4"), 35 × 47.62 × 137 mm (1 7/8"), 40 × 53.97 × 160 mm (2 1/8"), 45 × 60.32 × 180 mm (2 3/8"), 50 × 66.67 × 200 mm (2 5/8") or 60 × 82.55 × 240 mm (3 1/4").
Always check the propeller shaft diameter, the inner diameter of the bearing housing or shaft strut, and the available mounting or installation length before ordering and installation.
