Water and Grease Lubrication

The Radice shaft seal incorporates a 12 mm water inlet for connection to a water scoop, providing water supply to the shaft sealing installation.

A separate grease inlet allows silicone grease to be supplied to the double lip seal arrangement. The water and grease connections provide separate lubrication paths within the assembly.

Construction and Included Components

Flexible rubber shaft seal bellows with double lip seals.
Integrated water inlet connection.
Separate grease inlet connection.
Stainless steel hose clamps.
Silicone grease tube.
Mounting clip for the grease tube.

Temperature Resistance

Component	Operating Temperature Range
Seals	-10°C to +80°C
Outer Bearings	-20°C to +140°C

Selection and Installation

The correct Radice propeller shaft seal must be selected using two primary dimensions:

Propeller Shaft Diameter: 22, 25, 30, 35 or 40 mm.
Stern Tube Connection Diameter: 39, 42, 45, 48, 54 or 60 mm, depending on the shaft size.

Models with the same shaft diameter may have different stern tube connection diameters. Before ordering, verify both dimensions and ensure that a suitable water supply is available for the Ø12 mm inlet.
