This heavy duty Bosch style rotor is engineered for demanding mining applications where high vibration, dust and heat are common. Designed for 12V electrical systems with a 55A alternator rating, it delivers reliable performance under continuous heavy load. Precision balanced and manufactured to tight tolerances, the rotor helps reduce vibration and noise while supporting consistent charging output to keep electrical systems and accessories operating smoothly in off road and industrial equipment.

Constructed with high temperature insulation, a hardened machined shaft and a corrosion resistant finish, this rotor is built to extend alternator service life in harsh environments. It is quality tested for durability and is suitable as a replacement in Bosch style alternator assemblies where a 12V 55A rotor is specified. Always confirm exact fitment with the Parts Checker before purchase and have installation carried out by a qualified technician to ensure correct alignment and electrical connections.
