The half ring of the adjacent bearing, identified by code H 12010, is an essential component in the ASL25 diesel engine's crankshaft support system. This semi-circular ring is designed to fit around the bearing housing, ensuring the precise positioning and secure retention of the crankshaft within its seat. By maintaining correct axial alignment and supporting rotational loads, it plays a crucial role in minimizing friction and wear. Made from durable, high-strength materials, the half ring ensures the longevity and operational stability of the engine, particularly under continuous mechanical stress.
