BOWER MU-1209 Deep Groove Ball Bearing | 45x85x19mm | High-Load Industrial Grade

The BOWER MU-1209 is a premium single-row deep groove ball bearing engineered for demanding industrial environments requiring superior rotational accuracy and load distribution. Constructed from high-carbon chromium steel (SAE 52100), this bearing delivers a dynamic load rating (Cr) of 32.5 kN and a static load rating (Cor) of 19.3 kN, positioning it as a robust solution for heavy machinery. Its precision-ground raceways minimize friction and heat generation, supporting limiting speeds up to 8,500 RPM under grease lubrication. The robust internal geometry ensures operational stability, while the standard C3 internal clearance accommodates thermal expansion inherent in high-speed motor and gear applications. Designed for maximum uptime and interchangeability, the MU-1209 is the definitive choice for Maintenance, Repair, and Operations (MRO) professionals seeking reliable performance in critical applications such as electric motors, industrial pumps, conveyor systems, and agricultural machinery. BOWER’s commitment to exacting manufacturing standards ensures optimal vibration reduction and extended service life compared to standard grade equivalents. Investing in the MU-1209 translates directly into reduced maintenance cycles and significantly lowered total cost of ownership (TCO) for your capital equipment.
