NSK 6209-2Z/C3 Metal Shielded Single Row Deep Groove Ball Bearing 45x85x19mm

The NSK 6209-2Z-C3 is a precision deep groove ball bearing (45x85x19mm) engineered for high-speed applications requiring both contamination protection and thermal clearance management. Manufactured to NSK's stringent Japanese quality standards, this bearing features non-contact metal shields on both sides (2Z) that effectively exclude particulates while retaining factory-applied grease, with minimal frictional drag to support elevated rotational speeds. The C3 radial internal clearance accommodates thermal expansion during operation, preventing internal preload and ensuring consistent performance under fluctuating temperatures. This combination makes the 6209-2Z-C3 particularly well-suited for electric motors, fans, compressors, pumps, and gearboxes where both speed and thermal variation are factors. Constructed from premium bearing steel with optimized raceway geometry, this shielded bearing delivers reliable, low-vibration operation and extended service life, providing engineers and maintenance professionals with a durable, high-performance solution for demanding operating conditions.
