Aluminum Bronze Bar Outer/Inner Diameter&Lenth customized The tail shaft is generally composing of flanges, shafts, journals, conical shafts, and studs. The copper sleeve of the tail shaft is installing on the tail shaft tube of the journal. For ships with water lubrication, the stern shaft journal is generally equipping with bearings to prevent journal friction and corrosion, and the bearings are generally assembled on the shaft with interference fit. The working conditions of the stern shaft are relatively harsh, not only susceptible to corrosion by seawater, but also twisted and subjected to bending alternating stress, resulting in various faults. The supporting and sealing journals of the stern shaft may experience scratches, excessive wear, and rust due to improper clearance, misalignment of the axis, and poor lubrication. The red sleeve and seam of the copper sleeve may become loose and crack due to insufficient or excessive interference. The transition and keyhole areas of the conical shaft section may experience cracks due to fatigue, vibration, and impact. The journal and shaft stem may also rust due to poor seal
