The Crankshaft Main Bearing Set supports the crankshaft during its rotation within the engine block. It holds the crankshaft in proper alignment, ensuring smooth and stable engine operation. Minimizing metal to metal contact reduces friction and prevents wear between rotating and stationary engine parts. The set distributes loads generated during combustion, helping maintain engine balance.Attributes:• Used for crankshafts with 0.25mm undersize.• Maintains proper alignment of the crankshaft during rotation.• Damps vibrations from crankshaft movement during cycles.Applications: The Crankshaft Main Bearing Set is supports the crankshaft, allowing it to rotate freely while maintaining alignment and reducing friction under high loads generated during engine operation.
