• Bearing alternating load: Crankshaft bearing can bear alternating load and high-speed friction.
• Driving auxiliary devices: Crankshaft bearings are also used to drive the steam distribution mechanism of the engine and other auxiliary devices.
• Structural stability: it is composed of upper and lower bearing shells, which provides structural stability.
• Improve engine stability: Crankshaft main bearing makes the vehicle run more smoothly by balancing stability and adjusting clearance.
• Free elastic potential and fit interference: the radius of curvature of the bearing bush in the free state is slightly larger than the radius of the seat hole, and the difference between its diameters is called free elastic potential or opening amount, so as to ensure that the bearing bush does not turn, move or be depressed when working.
