As the leading ship supplier in Ross Dependency, Propeller Alignment Check, we specialize in delivering high-quality Rudder Post Bearings with unmatched speed and reliability. Trusted by shipowners and masters worldwide, our team ensures your vessel gets everything it needs — on time, every time.
Rudder post bearings are critical components in marine propulsion systems, supporting the rudder's weight and ensuring smooth steering. They reduce friction between the rudder post and hull, enabling precise vessel maneuverability. Typically made of durable materials like bronze or composite, they withstand harsh marine environments.
Size: Typically ranges from 50 mm to 1000 mm in diameter, depending on vessel size.
Grade: Commonly complies with ISO 199 or ASTM standards, such as ASTM A148 for cast steel.
Viscosity: Lubrication viscosity varies (ISO VG 68 to VG 220) based on operating conditions.
Buoyancy: Not directly applicable; bearings are designed for load capacity, not buoyancy.
Material: Often made of bronze (C93200), stainless steel (316L), or composite polymers.
Load Capacity: Ranges from 50 kN to 2000 kN, depending on design and application.
Operating Temperature: -20°C to +80°C, with specialized options for extreme conditions.
Corrosion Resistance: High, especially in seawater, due to material selection and coatings.
Maintenance: Requires periodic greasing or oil lubrication for optimal performance.
Alignment Tolerance: Typically within 0.1 mm/m to prevent excessive wear.
Rudder Post 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.
