SKF angular contact bearings are built to carry radial and axial loads at the same time. The raceways are offset, so the balls contact them at an angle. This gives the bearing a high axial capacity in one direction. You will find them in machine tool spindles, pumps, and gearboxes where precision and rigidity matter. MR Industrial Accessories LLC supplies this line.
The part number tells you a lot. Take S71908 CD/P4A: the 719 series sets the basic size, the S prefix points to a special execution, CD covers the contact angle and internal raceway design, and /P4A is the precision class, with tolerances similar to P4. Reading these codes correctly is the first step in choosing the right bearing.
These bearings show up in operations that need high accuracy and speed. You will see them in milling and CNC lathe spindles, process centrifugal pumps, screw compressors, and power transmission gearboxes. Automation equipment and textile machinery also use them. Because they take combined loads, they fit assemblies where the shaft must stay rigid, such as machine tool main spindles.
When selecting one, look at the main direction of the axial load, the precision level you need, and the lubrication conditions. Mounting is usually in pairs, with an O, X, or tandem arrangement, to set preload. Check shaft and housing alignment carefully, since these bearings do not tolerate misalignment well. Sealing and lubrication should match the working environment: temperature, speed, and contaminants all play a role.
For replacements, SKF angular contact bearings can be swapped with other brands that share the same standard dimensions and precision class. But do not stop at bore, outer diameter, and width. Contact angle and internal design can differ between makers. Compare the technical data and ask our team to confirm a suitable equivalent.

Frequently asked questions
- What does the CD suffix mean in an SKF bearing?
- CD indicates a design with a 15° contact angle and a brass or polyamide window cage, depending on the series. This affects axial load capacity and limiting speed. For a precise reading of any code, contact us with the full part number.
- How are angular contact bearings mounted?
- They are typically mounted in pairs in an O, X, or tandem arrangement to adjust preload. Alignment must be controlled, and mounting force should be applied to the correct ring. Follow the manufacturer's instructions and use suitable tools.
- Can I replace an SKF bearing with another brand?
- Yes, if the standard dimensions and precision class match. Also check the contact angle and internal design, as these can vary. At MR we help you find a suitable equivalent for your application.
