The RKB angular contact ball bearing is a component designed to withstand radial and axial loads in one direction. Its design with offset raceways allows oblique contact between balls and raceways, giving it a higher axial load capacity than a deep groove ball bearing. It is used in applications with combined loads, such as pumps, compressors, gearboxes and machine tool spindles. MR Accesorios Industriales sells this line for the Argentine industrial market.

The designation of these RKB angular contact bearings is based on the dimension series. Examples such as 70/500, 70/530 and 70/560 correspond to the 70 series, which is characterized by a thin section and a large bore diameter. The number after the slash indicates the bore diameter in millimeters. This nomenclature makes it possible to quickly identify the size and series, making selection easier according to the available space and load requirements.

In Argentine industry, angular contact bearings are used in pumping equipment, screw compressors, gearboxes and milling machine and lathe spindles. They are also found in textile machines, cranes and power transmission systems. Their ability to withstand combined loads makes them suitable for applications where precision and rigidity are important, such as machine tool spindles and high-speed equipment.

To correctly select an angular contact bearing, it is essential to consider the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting requires attention to alignment and axial clearance, which can be adjusted by mounting in pairs. Proper lubrication, whether with grease or oil, extends service life. Seals or shields prevent contamination, although in high-speed applications an open design may be preferred to facilitate heat dissipation.

There are equivalents between brands for angular contact bearings, but each manufacturer may have variations in suffixes and tolerances. When looking for a replacement, it is advisable to verify the main dimensions and load conditions. MR Accesorios Industriales can advise you to find the option compatible with your equipment, whether you bring the part number of another brand or an unidentified part.
