SKF NKIS 50 needle bearing

Product detailed description

SKF NKIS 50 is a needle roller bearing designed for applications where high load capacity is required with limited radial space. This bearing is characterized by its compact design and is equipped with an inner ring, which allows its use even in cases where it is not possible to use hardened and ground shafts.

The bearing has an inner diameter (d) of 50 mm, an outer diameter (D) of 80 mm and a width (B) of 28 mm. It is made of high-quality steel, which guarantees its high resistance and long service life. Needle roller bearings of this series are equipped with a pressed steel cage, which ensures precise needle guidance and minimizes friction. The cage is designed to allow effective lubrication through a circumferential groove with lubrication holes.

SKF NKIS 50 is a seal-less bearing, which means that it is suitable for applications where external lubrication and protection against contamination are provided. The operating temperature range of the bearing is from -20 °C to +100 °C, which allows its use in various climatic conditions. The bearing has normal radial clearance and meets the accuracy class P0/PN, which corresponds to ABEC 1.

The weight of the bearing is 0.518 kg, which is an important parameter in the design of mechanisms where weight is a critical factor. Due to its properties, the SKF NKIS 50 is ideal for use in industrial applications such as gearboxes, compressors, pumps and other equipment where reliability and high load capacity are required with minimal dimensions.
