NTN 62/22 C4 Deep Groove Ball Bearing 22x50x14

Overview

The NTN 62/22 C4 is a single row deep groove ball bearing with dimensions of 22x50x14 mm and increased C4 internal clearance. It is designed for applications operating under high rotational speeds, elevated temperatures and conditions where significant thermal expansion occurs. The C4 clearance exceeds the standard C3 clearance, making the bearing particularly suitable for demanding industrial environments requiring maximum operational reliability.

Industrial Applications

NTN 62/22 C4 is widely used in electric motors, industrial pumps, gearboxes, compressors, conveyors, agricultural machinery, industrial fans, machine tools and power transmission equipment. It operates together with rotary shaft seal, oil seal, shaft seal, radial shaft seal, bearing housing, transmission seal, industrial sealing systems and rotating shafts in OEM and maintenance applications.

Construction

The bearing features precision-ground deep raceways and a single row ball design that provides low friction and excellent running accuracy. The increased C4 internal clearance compensates for thermal expansion during operation, reducing internal stress and improving bearing life in high-speed and high-temperature applications.

Material

Manufactured from premium through hardened bearing steel, the NTN 62/22 C4 offers excellent fatigue strength, wear resistance and dimensional stability. Combined with proper grease or oil lubrication, it delivers reliable long-term performance under continuous industrial operating conditions.
