SKF NK 28/30 needle bearing without inner ring

Product detailed description

SKF NK 28/30 is a needle roller bearing without an inner ring, designed for applications where high load capacity is required with limited radial space. The bearing has an outer diameter of 37 mm, an inner diameter of 28 mm and a width of 30 mm. It is made of high-quality steel, which guarantees long service life and reliability in operation.

This bearing belongs to the category of single-row needle roller bearings and is equipped with a pressed steel cage, which ensures precise needle guidance and minimizes friction. The bearing does not have an inner ring, which allows it to be used directly on a hardened and ground shaft, thus saving space and reducing the weight of the entire mechanism.

The operating temperature range of the bearing is from -20 °C to +100 °C, which allows it to be used in various industrial applications. The bearing is unsealed, which means that it is necessary to provide suitable lubrication, which can be applied through a circumferential groove with lubrication holes.

The running accuracy of the bearing is in class P0/PN, which corresponds to ABEC 1, and provides sufficient accuracy for most common applications. The normal radial clearance guarantees optimal operational stability and balanced performance. The total weight of the bearing is 0.078 kg, which contributes to its easy handling and installation.

SKF NK 28/30 is the ideal solution for applications requiring compact and efficient bearing solutions with high load capacity and reliability.
