SKF 70 series angular contact bearings are precision components built for combined radial and axial loads acting in one direction. Their single-row layout with angular contact raceways suits setups that demand accuracy and rigidity, such as machine tool spindles and measuring equipment. We supply this line as part of our high-precision bearing range for customers across the United States and Latin America.

Reading the code helps you order the right bearing. The base number, such as 7002, carries the size information: 70 is the thin-section series, and the last two digits give the bore diameter. Suffixes then define the execution: CD is the internal design with a 15° contact angle and optimized load capacity; P4 is the precision class with very tight dimensional and running tolerances; ADGA means a universal arrangement of two bearings mounted in tandem with light preload and reduced axial clearance. So a 7002 CD/P4ADGA is a matched pair ready to mount as a set.

Typical applications include spindles on milling machines, grinding machines, and machining centers, where speed and precision matter. They also show up in drill heads, metrology equipment, high-accuracy gearboxes, and textile or printing machinery. Plants that need to hold tight tolerances and high repeatability often rely on them. Because they can run at high speeds, they work well with oil or special grease lubrication.

Selection starts with the direction of the axial load: these bearings take thrust in one direction only, so they are normally mounted in opposed pairs or in tandem. The ADGA arrangement comes paired and preloaded from the factory, which simplifies mounting and keeps axial clearance to a minimum. Check alignment between shaft and housing, and use the right adjustment method, whether a precision lock nut or shims. Use the lubricant specified for the operating speed and temperature, and choose sealing based on the environment; add extra protection where contaminants are present.

On equivalences, precision angular contact bearings are made to international standards that allow interchange between brands when dimensions, precision class, and arrangement match. Suffixes are not always equivalent, though: a SKF P4 may have a counterpart in another brand, but tolerances and preloads can differ. When replacing, verify not only the base code but also the internal design and pairing. We can help you find the right option for your application.
