Angular contact bearings from SKF handle radial and axial forces together, in one direction, thanks to a raceway geometry that is set at an angle. That layout supports rigid running at elevated speeds, which is why these bearings turn up in equipment where accuracy matters. MR Industrial Accessories LLC supplies them from Miami to customers throughout the United States and in several Latin American countries.
The part number tells you most of what you need. Take 7020 ACD/P4ATBTC: 70 is the dimension series, 20 is the size code, ACD covers the contact angle and internal design, P4A is the precision class, and TBTC identifies the set type, a universal triplex. In 71940 ACD/P4ATBTC, the 719 prefix points to the thin-section series. Reading these blocks separately makes it easier to confirm that a replacement matches what is already in the machine.
Typical installations include machine tool spindles, pumps, compressors, electric motors and power transmission equipment. Because the bearings take combined loads, they are arranged in tandem, back-to-back or face-to-face, depending on how the equipment is built and which way the forces travel.
Selection comes down to load size and direction, running speed and the conditions around the bearing. Open bearings depend on external lubrication and a clean environment; sealed versions hold lubricant in place. Internal clearance and preload have to suit the application. At mounting, alignment needs to be precise and impacts on the raceways avoided, and correct lubrication is what keeps service life where it should be.
Bearings that follow the same dimensional and precision designation can be exchanged across brands, including FAG, NSK and NTN, but tolerances and contact angle still need checking, since suffixes are not always equivalent from one maker to another. For a replacement, compare the technical data and have someone confirm the match before ordering.

Frequently asked questions
- What does the ACD suffix indicate in an SKF bearing?
- It identifies an internal design with a 25° contact angle and a glass fiber reinforced polyamide cage, which affects axial load capacity and limiting speed. Check the data sheet for your application or contact us.
- How are angular contact bearings mounted?
- They usually go in pairs, in tandem, back-to-back or face-to-face, according to the direction of the loads. Preload and alignment need to follow the manufacturer's instructions, since incorrect mounting shortens service life.
- Can they be replaced with bearings from another brand?
- They can be exchanged when dimensions and precision class match, but the contact angle and suffixes must be verified. FAG and NSK use their own designations. Contact us to confirm the exact equivalence.
