SKF NA 4903.2RS needle bearing

Product detailed description

SKF NA 4903.2RS is a needle roller bearing designed for applications requiring high load capacity in limited space. This bearing has an inner diameter of 17 mm, an outer diameter of 30 mm and a width of 14 mm, making it a compact solution for various industrial applications. It is made of high-quality steel, which guarantees long service life and reliability in operation.

The bearing is equipped with a pressed steel cage, which ensures precise needle guidance and minimizes friction. A double-sided rubber lip seal provides effective protection against dirt and moisture, contributing to an extended bearing life. These seals are designed to keep the lubricant inside the bearing and prevent it from leaking.

SKF NA 4903.2RS is a single-row bearing with normal radial clearance, which means it is suitable for applications where special requirements for running accuracy are not required. The bearing falls into the accuracy class P0/PN, or ABEC 1, which is the standard accuracy for most industrial applications.

The bearing is capable of operating in a temperature range from -20 °C to +120 °C, which allows it to be used in various climatic conditions. Lubrication is provided through a circumferential groove with lubrication holes, which allows for easy maintenance and extended service intervals.

Weighing only 0.04 kg, this bearing is lightweight, which contributes to reducing the overall weight of the equipment in which it is used. Thanks to its properties, the SKF NA 4903.2RS is ideal for applications in the automotive industry, mechanical engineering and other areas where high load capacity and reliability in a compact design are required.
