Rudder pintle bearings are crucial components in marine propulsion systems, providing support and alignment for the rudder stock. They ensure smooth rotational movement of the rudder, enhancing steering control and vessel maneuverability. These bearings are designed to withstand high loads and harsh marine environments for reliable performance.

Size: Typically ranges from 50 mm to 500 mm in diameter, depending on vessel size.

Grade: High-grade bearing materials, often meeting ISO 4378 or DIN 1494 standards.

Viscosity: Lubrication viscosity ranges from ISO VG 68 to VG 150, depending on operating conditions.

Buoyancy: Not applicable, as rudder pintle bearings are submerged but not designed for buoyancy.

Material: Commonly made of bronze, stainless steel, or composite materials like PTFE-lined bearings.

Load Capacity: Designed to handle radial loads up to 500 kN, depending on size and design.

Operating Temperature: -20°C to +80°C, suitable for marine environments.

Corrosion Resistance: High, often with galvanic protection or seawater-resistant alloys.

Maintenance: Requires regular greasing or oil lubrication for optimal performance.

Installation: Fitted into stern frame or rudder stock with precise alignment tolerances.

Rudder Pintle Bearings and Marine Propulsion products typically comply with maritime standards such as ISO, ABS, DNV, and other classification society requirements. For specific compliance details, refer to the product documentation or manufacturer specifications.
