Resin Rubber Water Lubricated Propeller Shaft Bearings English Series 1"–2 1/2"

Resin Rubber Water Lubricated Propeller Shaft Bearings English Series are designed to support and guide rotating propeller shafts in marine propulsion installations. The bearings feature a resin outer housing combined with a rubber internal bearing lining and are intended for water-lubricated operation.

The English Series includes four configurations with shaft diameters from 1" to 2 1/2", external bearing diameters from 1 1/2" to 3 1/4" and overall lengths from 100 to 250 mm.

Resin Housing with Rubber Bearing Lining

Each bearing features a cylindrical resin outer housing and an internal rubber bearing surface. The resin housing forms the external supporting structure, while the rubber lining provides the contact surface for the rotating propeller shaft.

Water-Lubricated Operation

These shaft bearings are designed for hydro-lubricated marine propulsion systems. Water lubrication supports smooth shaft rotation and helps reduce friction and wear during operation.

English Series Design

The English Series consists of resin and rubber shaft bearings with imperial internal and external diameters. The manufacturer's catalogue also provides corresponding metric values for dimensional reference.

The overall bearing length is specified in millimetres.

Bearing Dimensions

The technical drawing identifies three dimensions:

Ø A: Internal bearing diameter corresponding to the propeller shaft.
Ø B: External bearing diameter.
C: Overall bearing length.

Available Models and Dimensions

The following table lists all four English Type configurations according to the technical catalogue.
