DKF RNU 4911 needle bearing without inner ring

Product detailed description

DKF RNU 4911 is a needle roller bearing without an inner ring, designed for applications where space requirements need to be minimized and load capacity maximized. This bearing has an outer diameter of 80 mm, an inner diameter of 63 mm and a width of 25 mm, making it suitable for various industrial applications where these dimensions are critical.

The bearing is made of high-quality steel, which ensures its long life and wear resistance. The steel cage provides stability and precise needle guidance, reducing friction and increasing the efficiency of force transmission. The hole profile is cylindrical, which allows easy mounting on the shaft without the need for additional modifications.

This type of bearing is specific in that it does not contain an inner ring, which means that it is mounted directly on the shaft. This allows the use of a larger diameter of the rollers, which increases the load capacity of the bearing. The normal bearing clearance ensures optimal operation under normal load and temperature conditions.

DKF RNU 4911 is ideal for applications where high load capacity and reliability are required, such as gearboxes, pumps or compressors. Thanks to its technical properties and design, this bearing is suitable for demanding operating conditions where high precision and long component life are required.
