Angular contact bearings from SKF handle radial and axial forces at the same time. The angled raceway design delivers the rigidity and precision that demanding rotating equipment requires. We supply these bearings to maintenance and purchasing teams across the United States, Canada, Mexico and South America.
The part number tells you a lot before you open a catalog. In a designation such as 7009 ACD/P4ATGB or 7206 ACD/P4ATGB, the ACD block points to a refined contact angle paired with a polyamide cage built for strength. The P value that follows sets the precision class, for instance P4 for high accuracy. ATGB then signals a universal layout with reduced axial clearance, so the bearing can be installed in tandem, face-to-face or back-to-back arrangements. The bore diameter is 10 for the 7009 and 20 for the 7206.
You will find these bearings in machine tool spindles, high-pressure pumps, compressors, electric motors and power transmission assemblies. They suit plants where combined loading and accuracy go hand in hand, and their capacity for elevated speeds fits dynamic duty. Industries such as automotive, metalworking, food processing and petrochemical rely on them.
Selection comes down to load size and direction, rotation speed and the surrounding environment. Mounting calls for careful alignment and the right lubricant, grease or oil, matched to how the bearing runs. Open or shielded designs are available; where contamination is a concern, sealed versions make more sense. Set axial clearance to suit the application so the bearing is not overloaded.
Interchange is possible with other brands that use the same ISO designation, including FAG, NSK and NTN, provided dimensions and tolerances line up. Check the contact angle and precision class before substituting. Contact us to review equivalent options.

Frequently asked questions
- What does ACD indicate in an SKF bearing designation?
- ACD refers to a design with an optimized contact angle and a high-strength polyamide cage, which supports axial load capacity and limiting speed. It appears in high-precision applications.
- How do I decide between tandem, face-to-face or back-to-back mounting?
- It depends on the rigidity and clearance you need. Tandem arrangements take axial loads in one direction, while face-to-face or back-to-back setups manage loads in both directions with higher rigidity.
- Which lubricant should I use with these bearings?
- For general use, a quality grease works well; oil is preferred for high speeds or elevated temperatures. The final choice depends on operating conditions and sealing type.
