The Main Crankshaft Bearing Kit consists of two halves of bearings. The main bearings, which support the crankshaft within the engine block, and the connecting rod bearings, support the crankshaft within the connecting rods. These bearings are made of durable material to provide a low-friction surface for the crankshaft to rotate on.Attributes:• Ensure the bearings continue to function effectively and address any signs of wear and damage• Provided linear contact areas with outer rings to distribute loads on larger surface areasApplications:The Main Crankshaft Bearing Kit is used for service and maintenance to provide support and reduce friction for the crankshaft, which converts the reciprocating motion of the pistons into rotational motion and withstands high loads and rotational speeds.
