SKF RNA 4907 needle bearing without inner ring

Product detailed description

SKF RNA 4907 is a needle roller bearing without an inner ring, designed for applications where it is necessary to minimize radial dimensions while ensuring high load capacity. This bearing has an outer diameter D 55 mm, an inner diameter d 42 mm and a width B 20 mm. It is made of high-quality steel, which guarantees its high resistance and long service life.

The bearing is equipped with a steel cage, which ensures proper needle guidance and minimizes friction, thereby contributing to efficient operation. Due to the absence of an inner ring, it is suitable for applications where the inner surface of the shaft is sufficiently hard and precisely machined to serve as a rolling track.

The operating temperature range of the bearing is from -20 °C to +100 °C, which allows it to be used in various industrial conditions. The bearing is unsealed, which means that it is necessary to ensure proper lubrication and protection against external contamination.

SKF RNA 4907 is ideal for applications where high load capacity and compact dimensions are required, such as gearboxes, compressors and various types of industrial machinery. Its normal clearance ensures optimal operation under standard load conditions.
