Kubota Engine Bearing
Engine bearings are key components of Kubota engines. They are usually made of high-hardness, wear-resistant steel, divided into upper and lower parts, and are precisely installed between the crankshaft and the engine block, and between the connecting rod and the crankshaft. Supporting the crankshaft and connecting rod, ensuring smooth rotation and minimizing friction between moving parts. Thus extending the service life of the engine.
The four main functions of the engine main bearing :
- Support the crankshaft: Ensure that the crankshaft rotates stably in the engine block and maintain its correct positional relationship with other components.
- Reduce friction and wear: Rely on antifriction materials and lubricating oil films to reduce the friction between the crankshaft and the bearing, thus prolonging the service life of the engine.
- Transmit force and torque: Transmit the force and torque generated by the combustion pressure on the crankshaft to the engine block to achieve power output.
- Heat dissipation and sealing: Dissipate the heat generated by friction to prevent local overheating. Meanwhile, prevent the leakage of lubricating oil to ensure the normal operation of the lubrication system.
