Product Description

Product Description

SKF cylindrical roller bearings are radial rolling bearings with line contact between cylindrical rollers and raceways. They are designed to carry heavy radial loads, operate at moderate to high speeds, and offer high stiffness, low friction, and extended service life. Most types allow axial displacement of the shaft relative to the housing in one or both directions, making them widely used in gearboxes, electric motors, pumps, compressors, rolling mills, fans, machine tools, and other heavy-duty industrial applications.
