Crosshead babbitt thickness
Thread Content
Question: What is the typical thickness of crosshead babbitt alloy? Why was such a thickness chosen? What problems can occur if it’s too thick or too thin?
It’s generally around 3MM. The manufacturer designs the thickness of the babbitt alloy based on the rotor weight, rotational speed, and the lubrication method for the bearing shells.
Up to 3 mm; it cannot be thick. Bus alloy lubrication is acceptable, but since it is soft, it cannot be thick – just enough to meet the requirements for lubrication channels and similar purposes
1.5MM ones are available too; it should be related to the size of the unit and the load on the crosshead!
Is the bus alloy of the crosshead that thick? How can the alloy of the bearing bush have a thickness of 0.1–0.3 mm?
