CEF Water-Lubricated Rubber Propeller Shaft Bearings Without Outer Sleeve Ø22–40 mm

CEF Water-Lubricated Rubber Propeller Shaft Bearings Without Outer Sleeve Ø22–40 mm

CEF Water-Lubricated Rubber Propeller Shaft Bearings are designed for marine shaft line installations. Manufactured from synthetic rubber, these bearings feature a sleeveless construction without an external metallic or laminated housing.

The range includes seven dimensional configurations with internal diameters from 22 to 40 mm, external diameters from 29 to 54 mm and overall lengths from 75 to 140 mm.

Synthetic Rubber Construction

Each bearing is manufactured from synthetic rubber and designed for water-lubricated operation in marine propeller shaft systems.

Without External Sleeve

These CEF shaft bearings are supplied without a separate external sleeve. The outer bearing surface is formed by the rubber body itself.

This construction distinguishes the range from propeller shaft bearings with metallic or laminated external shells.

Water-Lubricated Shaft Bearing

The bearings are designed for use in water-lubricated marine propulsion shaft installations, providing a bearing surface for the rotating propeller shaft.

Metric Bearing Dimensions

All dimensions in this range are expressed in millimetres:

• Internal Diameter (ID): Bearing diameter corresponding to the propeller shaft.
• External Diameter (OD): Outside diameter of the rubber bearing.
• Length (L): Overall bearing length.

Available Models and Dimensions

The following table lists all seven CEF configurations according to the supplied catalogue.

Alternative Bearing Dimensions

Two shaft diameters are available with alternative external dimensions:

• 22 mm shaft: External diameter 29 mm with length 75 mm, or external diameter 36 mm with length 80 mm.
• 25 mm shaft: External diameter 36 mm with length 100 mm, or external diameter 40 mm with length 120 mm.

Bearing Size Selection

Select the appropriate CEF propeller shaft bearing according to three dimensions:

• Shaft: Internal bearing diameter corresponding to the propeller shaft.
• Shaft Tube: External bearing diameter.
• Length: Overall bearing length.

Check all three measurements against the existing marine shaft installation before selecting the required bearing.
