SKF NK 22/20 needle bearing without inner ring

Product detailed description

SKF NK 22/20 is a needle roller bearing without an inner ring, designed for applications where high load capacity is required in a limited space. This bearing is made of high-quality steel, which ensures its long service life and reliability. It has an outer diameter (D) of 30 mm, an inner diameter (d) of 22 mm and a width (B) of 20 mm.

The bearing is designed as a single row, which means that it contains one row of needles, which are housed in a pressed steel cage. This cage ensures optimal guidance of the needles and minimizes friction, contributing to the smooth operation of the bearing. SKF NK 22/20 is unsealed, which means that it is uncovered and requires regular maintenance and lubrication. Lubrication is carried out via a circumferential groove with lubrication holes, which allows for easy and efficient replenishment of lubricant.

This bearing is designed to operate in a temperature range from -20 °C to +100 °C, which makes it suitable for various industrial applications. The running accuracy is in class P0/PN, or ABEC 1, which is the standard accuracy for common applications. The internal radial clearance is normal, which ensures optimal operation under standard conditions.

SKF NK 22/20 is ideal for applications where high load capacity is required in a limited space, such as gearboxes, compressors or pumps. Due to the absence of an inner ring, it can be used directly on the shaft, which must be hardened and ground to ensure proper bearing function. The total weight of the bearing is 0.037 kg, which contributes to its easy handling and installation.
