NN3052-AS-K-M-SP Precision Cylindrical Roller Bearings Features and Advantages

High Precision: These bearings offer extremely high precision, with a precision grade of P4, making them suitable for applications requiring high rotational accuracy.

High Load Capacity: The line contact between the cylindrical rollers and raceways allows them to bear large radial loads.

Low Friction: The line contact between the rollers and raceways results in low friction, enhancing mechanical efficiency.

Floating Characteristics: There is no constraint force between the rollers and the raceways without flanges, allowing compensation for length changes during rotational motion, making them suitable as floating bearings.

Application: Widely used in machine tool manufacturing, precision machining equipment, heavy-duty and high-speed machinery, aerospace, research and experimental equipment, and other fields.
