SKF NA 4905 needle bearing

Product detailed description

SKF NA 4905 is a needle roller bearing that belongs to the category of solid needle roller bearings with a single row needle arrangement. This bearing is designed with an inner ring and is made of high-quality steel, which guarantees its high resistance and long service life. The bearing has a cylindrical profiled bore with an inner diameter of 25 mm, an outer diameter of 42 mm and a width of 17 mm. Its total weight is 0.088 kg.

SKF NA 4905 is designed without seals, which means that it is uncovered and is suitable for applications where it is not necessary to prevent the ingress of dirt or liquids. The bearing is equipped with a pressed steel cage that ensures proper needle guidance and minimizes friction. The internal radial clearance is normal, which is standard for most applications where special clearance adjustments are not required.

The bearing's operating temperature range is from -20 °C to +100 °C, which allows it to be used in various environments and applications. The running accuracy is in class P0/PN, or ABEC 1, which is the basic accuracy class suitable for common industrial applications. The bearing is equipped with a circumferential groove with lubrication holes, which allows for easy and effective lubrication during operation.

SKF NA 4905 is ideal for applications where it is necessary to ensure high load capacity in limited space, such as gearboxes, compressors or various types of machines. Its robust design and high-quality materials guarantee reliable performance even in demanding conditions.
