NSK Single Row Deep Groove Ball Bearing, Sealed, Steel Cage and Balls, 17 mm ID, 40 mm OD, 12 mm Width, Internal 6203DDUC3 N

NSK 6203DDUC3 N is a high-quality single row deep groove ball bearing with an inside diameter of 17 mm, outside diameter of 40 mm, and race width of 12 mm. The bearing is sealed on both sides with synthetic rubber seals (DDU variant) to protect against dust, water, and lubricant leakage, ensuring durability and reduced maintenance.

Featuring a steel cage and steel balls, this bearing supports both radial and axial loads efficiently. The internal clearance is C3, providing additional space for thermal expansion and applications with higher speed or shaft deflection.

The bearing offers a static load rating of 4.8 kN and a dynamic load rating of 9.55 kN, making it suitable for demanding industrial environments including mechanical machinery, HVAC equipment, agricultural machinery, and manufacturing systems.

The bore type is parallel, and it is part of the 2 Light series, characterized by its plain raceway design which emphasizes smooth rotational performance. This bearing includes two synthetic rubber seals to protect internal components from contaminants and maintain lubrication.

Steel cage and balls provide excellent wear resistance and dimensional stability. Internal clearance C3 allows for better thermal expansion in high-speed or heavy load conditions. Static and dynamic load ratings enable it to withstand significant operational pressures.

Single row deep groove design makes it versatile for various rotary machine applications.

Ideal for use in mechanical, fluid power, HVAC, manufacturing, and other industrial sectors. NSK bearings are known for their quality and reliability, contributing to longer machine life and reduced downtime.
