Allpa Bronze Rigid Inner Propeller Shaft Bearing with Neoprene Bush for Ø20–60 mm Shafts
The Allpa Bronze Rigid Inner Propeller Shaft Bearing is a fixed inner bearing assembly designed for inboard marine propulsion systems. It features a bronze housing with an integrated mounting flange, a neoprene bearing bush, an internally threaded connection for the stern tube and packing cord sealing.
The rigid bearing assembly is designed for installation at the inner end of the propeller shaft system, providing a bearing and sealing arrangement within the vessel.
Eight configurations are available for propeller shaft diameters from 20 to 60 mm, with corresponding stern tube diameters from 35 to 80 mm.
Key Features
- Bronze housing: Rigid bearing housing manufactured from bronze for marine applications.
- Fixed inner bearing: Designed for inboard propeller shaft installations.
- Neoprene bearing bush: Integrated bearing component for the rotating propeller shaft.
- Fixed mounting flange: Flanged housing for attachment to the vessel's structure.
- Internal threaded connection: Designed for connection to a compatible stern tube.
- Packing cord sealing: Sealing arrangement incorporated into the bearing assembly.
- Eight shaft sizes: Available for Ø20, Ø25, Ø30, Ø35, Ø40, Ø45, Ø50 and Ø60 mm shafts.
- Multiple threaded connections: Internal metric thread sizes from M35×1.5 to M80×2.

Bronze Housing and Mounting Flange
The bearing assembly incorporates a rigid bronze housing with a fixed mounting flange. The flange provides a mounting surface for securing the assembly within the vessel's propeller shaft installation.
The overall housing dimensions and flange dimensions vary according to the selected shaft diameter.
Neoprene Inner Bearing
The integrated neoprene bearing bush is designed to support the rotating propeller shaft within the housing.
The bearing forms part of the vessel's inboard propulsion shaft support arrangement.
Internal Threaded Stern Tube Connection
The bronze housing incorporates an internal metric thread for connection to a compatible stern tube.
Available threaded connections include M35×1.5, M40×1.5, M45×1.5, M50×1.5, M55×2, M60×2, M65×2 and M80×2.
The correct thread size must be matched to the stern tube connection during installation.
Packing Cord Sealing
The rigid bearing assembly incorporates a packing cord sealing arrangement for the inboard propeller shaft installation.
The packing cord provides sealing around the propeller shaft within the bearing housing assembly.
