The alternator roller bearing supports the rotor within the alternator, allowing it to spin freely and efficiently while the engine is running. It reduces friction between moving parts, which helps improve the alternator's performance and longevity. By minimizing wear and heat generation, the roller bearing ensures reliable electrical output and reduces the risk of failure in the alternator system. Proper lubrication and maintenance of the bearing are essential for optimal functionality.
there are many types of bearings .... 1)ball bearing 2)roller bearing 3)ball thrust bearing 4)roller thrust bearing & 5)tapered roller thrust..
