The CBT3282-2001 Flat Watertight Friction Upper Rudder Bearing is a critical component in marine rudder systems, designed to ensure stable steering, watertight integrity, and long-term durability for various types of ships. It integrates support, load-bearing, sealing, and lubrication functions, directly influencing a vessel’s maneuverability and safety during navigation.
Superior Watertightness: Equipped with advanced sealing devices (e.g., stuffing boxes) to prevent seawater from entering the hull via the rudder stock connection, safeguarding hull safety.
Strong Load-Bearing Capacity: Bears radial loads from rudder blade hydrodynamic forces and axial loads from the rudder system’s gravity, ensuring stable rudder operation.
Precise Positioning & Flexible Rotation: Supports the rudder stock to maintain its correct position while reducing rotational friction, enabling smooth left-right rotation of the rudder blade for precise heading control.
Standard Compliance: Fully adheres to the CB/T3282-2001 standard, ensuring compatibility and interchangeability with most marine rudder systems.
Dual-Type Design: Available in Type A (no stop block) and Type B (with stop block, 2 hinge bolts for connection), adapting to different rudder system configurations.
Integrated Lubrication: Optional lubrication systems (oil filling holes, oil tanks) reduce friction between the bearing and rudder stock, extending service life.
Robust Construction: Bearing parts combine thrust roller bearings (for rudder weight) and vertical sliding bearings (for lateral forces), ensuring structural stability.
Modern Large Ships: Serves as the sole upper rudder bearing, bearing all rudder system weights and forces, eliminating the need for additional bottom supports.
Small Vessels: Works with rudder pins installed at the rudder blade bottom, forming a dual-support structure to enhance steering stability for inshore or coastal ships.
Bearing Part: Consists of a thrust roller bearing (bears rudder weight) and a vertical sliding bearing (resists lateral forces), ensuring balanced load distribution.
Sealing Device: Includes stuffing boxes and rubber gaskets to achieve Class A watertightness, preventing seawater intrusion even in rough sea conditions.
Connecting Components: Flanges and high-strength bolts (e.g., M30-M48) fix the bearing to the steering gear room deck, ensuring firm connection with the rudder stock and blade.
Lubrication System: Pre-installed oil filling holes and optional oil tanks enable regular lubrication, reducing wear and maintaining rotational flexibility.
Mounted on the deck of the ship’s steering gear room, at the upper end of the rudder stock—ensuring close alignment with the rudder system and easy access for maintenance.
Custom Manufacturing: Provides tailor-made bearings based on customer-specified rudder stock diameter, load requirements, and installation space.
Quality Assurance: All products undergo strict pressure testing, friction coefficient testing, and watertightness testing to meet marine industry standards.
After-Sales Support: Offers on-site installation guidance, maintenance training, and 12-month warranty service to resolve customer issues promptly.
Documentation Support: Supplies detailed technical drawings, installation manuals, and CB/T3282-2001 standard compliance certificates for customer reference.
