Osculati Rubber Propeller Shaft Stern Tube Bearings Ø22–40 mm

Osculati Rubber Propeller Shaft Stern Tube Bearings are cylindrical rubber bushings designed for supporting and guiding rotating propeller shafts in marine shaft line installations.

The Osculati 52.207 series includes seven dimensional configurations with shaft diameters from 22 to 40 mm, external bearing diameters from 29 to 54 mm and overall lengths from 75 to 140 mm.

Rubber Bearing Construction

The shaft line bushings are manufactured from rubber and feature an internal bearing surface corresponding to the selected propeller shaft diameter.

The external dimensions vary according to the selected configuration and the mounting requirements of the stern tube or shaft support assembly.

Marine Propeller Shaft Applications

These rubber bushings are intended for marine shaft line installations where a bearing surface is required to support and guide a rotating propeller shaft.

Metric Shaft and Bearing Dimensions

Both internal and external diameters are specified in millimetres. The manufacturer's technical drawing identifies three dimensions:

Ø A – Shaft Diameter: Internal bearing diameter corresponding to the propeller shaft.
Ø B – External Diameter: Outside diameter of the rubber bearing.
C – Length: Overall bearing length.

Available Models and Dimensions

The following table lists all seven configurations according to the Osculati technical catalogue. All dimensions are expressed in millimetres.

Osculati Code	Shaft Ø A (mm)	External Ø B (mm)	Length C (mm)
52.207.22	22	29	75
52.207.23	22	36	80
52.207.25	25	36	100
52.207.26	25	40	120
52.207.30	30	40	120
52.207.35	35	54	140
52.207.40	40	54	140

Alternative Bearing Dimensions

Two shaft diameters are available with alternative external diameters and lengths:

22 mm shaft: Ø29 × 75 mm or Ø36 × 80 mm.
25 mm shaft: Ø36 × 100 mm or Ø40 × 120 mm.

The remaining shaft diameters are available in the dimensional configurations specified in the table.

Bearing Size Selection

Select the appropriate Osculati rubber shaft bearing according to three dimensions:

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

For 22 mm and 25 mm shafts, more than one dimensional configuration is available. Check all three measurements against the existing stern tube or shaft support installation before selecting the required bearing.
