Universal Series Resin Rubber Water Lubricated Propeller Shaft Bearings are designed to support and guide rotating propeller shafts in marine propulsion systems. Manufactured with a resin outer housing and rubber bearing lining, these hydro-lubricated bearings provide durable construction and support smooth shaft rotation. The range includes eight configurations with metric shaft diameters from 25 to 60 mm, external bearing diameters from 1 1/2" to 3 1/4" (38.10–82.55 mm) and overall lengths from 100 to 240 mm. Each configuration combines a specific internal diameter, external diameter and bearing length for installation in the corresponding propeller shaft and stern tube arrangement.

Resin Rubber Water Lubricated Propeller Shaft Bearings Universal Series Ø25–60 mm

Universal Series Resin Rubber Water Lubricated Propeller Shaft Bearings are designed to provide support and guidance for rotating propeller shafts in marine propulsion installations. These bearings combine a resin outer housing with a rubber inner bearing lining and are intended for water-lubricated operation.

The Universal Series includes eight dimensional configurations with shaft diameters from 25 to 60 mm, external bearing diameters from 1 1/2" to 3 1/4" and overall lengths from 100 to 240 mm.

Resin Housing with Rubber Bearing Lining

Each bearing features a cylindrical resin outer housing and an internal rubber bearing surface. The resin housing provides the external supporting structure, while the rubber lining supports and guides 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.

Universal Series Design

The Universal Series consists of resin and rubber shaft bearings available in different dimensional configurations for marine propeller shaft installations.

The internal bearing diameter is specified in millimetres, while the external bearing diameter is specified in inches with corresponding metric values. The overall bearing length is given in millimetres.

Bearing Dimensions

The manufacturer's dimensional drawing identifies three measurements:

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 eight configurations according to the technical catalogue.

Bearing Size Selection

Select the appropriate Universal Series shaft bearing using three dimensions:

Shaft (A): Internal diameter corresponding to the propeller shaft, in millimetres.
Shaft Tube (B): External bearing diameter, in inches.
Length (C): Overall bearing length, in millimetres.

Use the complete combination of shaft diameter, external diameter and length when selecting a bearing for the propeller shaft and stern tube installation.
