What maintenance tips can ensure the durability of Rudder Stock

To ensure the durability of the rudder stock, maintenance needs to be carried out from multiple aspects.
Daily inspection is essential. Check the surface of the rudder stock regularly for signs of cracks, wear or deformation. Use non-destructive testing equipment, such as ultrasonic flaw detectors, to accurately detect fine internal cracks. Check the tightness of the connection parts between the rudder stock and the rudder blade, bearings, etc. to prevent abnormal wear or structural damage due to looseness. If the bolts are found to be loose, they must be tightened in time according to the specified torque.
Lubrication and maintenance are indispensable. Choose suitable high-quality grease and regularly inject it into the bearings and rotating parts of the rudder stock. Grease can reduce the friction coefficient, reduce wear and extend the service life of the rudder stock. Note that in bad weather or after long-term sailing, the frequency of lubrication should be appropriately increased to ensure that key parts are always in good lubrication.
Anti-corrosion treatment is the key point. Since the rudder stock is in a corrosive environment such as seawater for a long time, it needs to be well protected. Clean the surface regularly to remove attached dirt, salt and other corrosive substances. Apply anti-corrosion paint to form an isolation layer to prevent seawater erosion. For rudder stocks made of stainless steel or titanium alloy, although they have strong corrosion resistance, daily protection cannot be ignored. Protective oil can be applied regularly to enhance their corrosion resistance. In addition, reasonable control of the ship's navigation environment and avoiding long-term stay in highly polluted and highly corrosive waters can also help protect the rudder stock, improve its durability, and ensure safe and stable operation of the ship.
