NSK 6209/C3 Open Single Row Deep Groove Ball Bearing 45x85x19mm

The NSK 6209-C3 is a precision deep groove ball bearing (45x85x19mm) engineered for applications where thermal expansion and elevated rotational speeds demand enhanced internal clearances. Manufactured to NSK's stringent Japanese quality standards, this open-type bearing features the C3 radial internal clearance—a deliberately increased internal gap that accommodates thermal growth during operation, preventing unwanted preload and reducing the risk of premature failure. This makes the 6209-C3 particularly well-suited for electric motors, pumps, compressors, gearboxes, and high-speed drives where temperature fluctuations are common. Constructed from premium bearing steel with optimized raceway geometry, it delivers excellent load distribution, minimal vibration, and extended operational life. For engineers and maintenance professionals requiring reliable performance under demanding thermal and speed conditions, the NSK 6209-C3 provides a proven, high-integrity solution.
