Rotary Vane Steering Gear · Steering Gear
The ThorShield Marine Shaft Coating System from Thordon Bearings Inc. is designed to protect marine propeller shafts from corrosion and wear, enhancing the longevity and reliability of the propulsion system. This system features a torque rating specified by the manufacturer’s datasheet and is compatible with hydraulic oil as the operating medium. Approved by DNV-GL under the model number TAM000009X, the ThorShield system includes critical components like rotary vane pumps, hydraulic power units (HPU), and magnetic valves. Common issues include bypass leakage caused by rotary vane seal failure, HPU motor bearing damage after extended use, and magnetic valve blockages due to oil contamination. To ensure optimal performance, Thordon Bearings recommends keeping a seal kit and solenoid valves on board for quick repairs, with a lead time of 3 to 8 weeks for spare parts delivery. Maintenance practices include hydraulic oil analysis every six months, flap seal inspections during docking, and monthly emergency steering exercises. Compliance with SOLAS regulations mandates conducting a hard-over test that must be completed within 28 seconds.
