SKF NK 30/20 TN needle bearing without inner ring

Product detailed description

SKF NK 30/20 TN is a needle roller bearing without an inner ring, designed for applications where high load capacity is required with minimal dimensions. This bearing has an outer diameter of 40 mm, an inner diameter of 30 mm and a width of 20 mm. Thanks to its design without an inner ring, it is ideal for applications where a hardened and ground shaft is already present, which serves as a raceway.

The bearing is made of high-quality steel, which guarantees its high resistance and reliability. It is equipped with a polyamide cage, which ensures optimal needle guidance and reduces friction. This type of cage is suitable for applications with operating temperatures ranging from -20 °C to +100 °C. The bearing is not equipped with a seal, which allows it to be used in applications where external lubrication is provided. Lubrication is supported by a circumferential groove with lubrication holes, which allows for efficient distribution of the lubricant.

SKF NK 30/20 TN is a single-row bearing, which means it contains one row of needles, and provides normal radial clearance. The running accuracy is in class P0/PN, which corresponds to the ABEC 1 standard. The bearing is suitable for applications with normal operating conditions, where high accuracy and reliability are required. With a weight of 0.06 kg, it is lightweight and easy to integrate into various mechanical systems. Due to its properties, it is ideal for use in industrial equipment, the automotive industry and other technical applications where compact and efficient bearing solutions are required.
