The main thrust bearing controls the correct location of the crank pins relative to the center of the cylinders. Marine Machinery, Engines & Controls. Firstly you can use a jack arrangement or you can use oil pressure which makes the shell come out of its seat. The stresses shown arise from the pre-tensioning of the main bearing studs. Spare parts, new, used and rebuilt parts, plain bearing production. as both rod and main bearing housing bores. Main bearings are an important part of a marine engine, responsible for converting sliding friction into rolling friction (the latter’s value being much lesser than its counterpart), thus helping the crankshaft to rotate freely and power a ship’s propeller adequately.. In tilting pad type of bearing a thrust collar is forged integrally with the thrust shaft. The Main Properties Engine Bearings Must Posses: Load Capacity (fatigue strength) is the maximum value of cycling stress that the bearing can withstand without developing fatigue cracks after an infinite number of cycles.
