Hydradrive Self-Aligning Thrust Bearing, Ø20mm For Model HD-108

Hydradrive Self-Aligning Propeller Shaft Thrust Bearing for HD-108 to HD-142 Ø20–60 mm

The Hydradrive Self-Aligning Propeller Shaft Thrust Bearing is designed for use in Hydradrive constant velocity marine propulsion systems. It provides a dedicated support point for the propeller shaft and transfers propeller thrust directly to the vessel's hull rather than through the engine and gearbox mountings.

The self-aligning thrust bearing arrangement simplifies propulsion shaft alignment and incorporates vibration-damping mounting components. This configuration allows softer engine mountings to be used and helps reduce the transmission of vibration through the propulsion installation.

The range includes thrust bearings for Hydradrive HD-108, HD-113, HD-115L, HD-125, HD-130 and HD-142 systems, with different configurations for propeller shaft diameters from 20 to 60 mm.

Key Features

• Self-aligning construction: Designed to simplify propeller shaft alignment.
• Propeller thrust support: Transfers axial thrust loads from the propeller shaft to the vessel's hull.
• Vibration isolation: Mounting arrangement incorporates vibration-damping components.
• Shaft clamping connection: Provides secure attachment to the cylindrical propeller shaft.
• Multiple shaft diameters: Available for shaft sizes from 20 to 60 mm, including 38.1 mm.
• Hydradrive compatibility: Versions for HD-108, HD-113, HD-115L, HD-125, HD-130 and HD-142.
• Marine propulsion application: Intended for use with Hydradrive constant velocity shaft systems.

Technical Specifications

Available Models and Shaft Diameters

The correct thrust bearing is selected according to the Hydradrive drive model and propeller shaft diameter.

Hydradrive Model Compatibility

• HD-108: Shaft diameters 20, 22, 25 and 30 mm.
• HD-113: Shaft diameters 30, 35 and 40 mm.

Thrust Transmission and Vibration Isolation

Hydradrive thrust bearings provide a dedicated mounting point for axial propeller loads. The thrust bearing transfers these loads to the hull through vibration-damping mounting bushes instead of transmitting them through the engine and gearbox mountings.

The self-aligning bearing configuration simplifies shaft installation and helps accommodate alignment differences within the propulsion system.

Installation and Selection

Before ordering, verify the following parameters:

• Hydradrive Model: HD-108, HD-113, HD-115L, HD-125, HD-130 or HD-142.
• Propeller Shaft Diameter: Required shaft size in millimetres.
• Clamping Connection: Compatibility with the existing propeller shaft.
• Installation Arrangement: Compatibility with the existing Hydradrive thrust bearing mounting system.

The bearing must be selected according to the specified Hydradrive model and propeller shaft diameter. Bearings with the same shaft diameter may have different article numbers depending on the drive model.
