6203 RS P66 DKF 17x40x12 deep groove ball bearing

Main description

The 6203 RS P66 DKF deep groove ball bearing with dimensions 17x40x12 mm is a precision compact bearing designed for applications requiring stable operation, contamination protection and low noise performance in small and medium mechanical systems.

A deep groove ball bearing is one of the most widely used bearing types, capable of handling radial loads and moderate axial loads in both directions. The 6203 size belongs to the globally recognized 62xx series, commonly used in electric motors, pumps, fans and general industrial equipment where compact design and efficiency are essential.

The RS version indicates a rubber seal on one side, providing protection against dust, moisture and debris while retaining lubrication inside the bearing. The P66 precision class ensures improved dimensional accuracy, reduced vibration and smoother operation, making this bearing suitable for applications where performance and reliability are critical.

Construction and design

The DKF 6203 RS P66 is a single row deep groove ball bearing with optimized raceway geometry for smooth and efficient rotation.

The RS sealing protects the internal components from contamination while maintaining proper lubrication. The enhanced P66 precision level improves running accuracy and reduces noise, especially in high speed or sensitive applications.

Its compact design ensures easy integration into assemblies where space is limited but consistent performance is required.
