TIMKEN NA 357 Deep Groove Ball Bearing - 35x72x17mm | Heavy Duty Precision DGBB
The TIMKEN NA 357 is a high-performance deep groove ball bearing engineered for demanding industrial environments requiring superior reliability and minimal maintenance. Constructed from proprietary high-grade alloy steel and featuring optimized raceway geometry, this bearing delivers exceptional load-carrying capacity (both static and dynamic) while maintaining C3 internal clearance specifications crucial for high-speed operation or applications subject to thermal expansion. The NA 357 ensures low friction torque and reduced heat generation, providing longer operational life and adherence to stringent ISO precision standards. It is dimensionally stable (35mm bore, 72mm OD, 17mm width) and typically features durable pressed steel cages for robust performance under vibration and acceleration loads.
Selecting the Timken NA 357 translates directly into operational savings and reduced downtime across critical machinery. Ideal for use in electric motors, pumps, gearboxes, HVAC systems, and material handling equipment, this bearing is designed to handle simultaneous radial and axial loads efficiently. Its optimized design minimizes noise and vibration, making it a crucial component for precision machinery where acoustic performance is a factor. As a Senior PM, I recommend the NA 357 for mission-critical applications where failure is not an option, offering a significant Total Cost of Ownership (TCO) advantage over lower-grade alternatives due to its industry-leading durability and lifespan.
