SKF angular contact bearings in the CD/P4ATBTB series come as four-row precision sets arranged in tandem, back-to-back. They suit machine tool spindles and other setups that combine axial and radial loads with high rigidity and speed. MR Industrial Accessories supplies this line and helps you match the right set to your assembly.
Break the code into three parts. CD is the angular contact design with a 15° contact angle and larger balls for higher capacity. P4A is the dimensional and rotational precision class, above P4. TBTB gives the arrangement: four bearings in tandem, back-to-back, tandem, back-to-back. Part numbers such as 7013 CD/P4ATBTB, 7015 CD/P4ATBTB, 7017 CD/P4ATBTB and 7028 CD/P4ATBTB follow that pattern and differ in bore diameter.
Typical applications include milling spindles, grinding machines, machining centers and high-speed heads, as well as lathe chucks, precision grinding spindles and metrology equipment. Metalworking, automotive, aeronautical and machine tool operations rely on them where spindle repeatability and rigidity affect part quality and tool life.
Selection depends on the combined axial and radial load, the maximum speed and the rigidity required. Mounting calls for cleanliness, shaft and housing alignment, and controlled preload. Grease or oil lubrication is chosen according to speed, while sealing follows the environment. Follow the specified tightening torque and nut adjustment sequence to avoid deforming the rings.
Precision angular contact bearings can be interchanged between manufacturers by designation, precision class and arrangement, but always confirm contact angle, preload and tolerances. Do not substitute a lower class for a P4A set when the spindle demands high accuracy. Check drawings or samples before mounting to verify interchangeability.

Frequently asked questions
- What does CD/P4ATBTB mean in an SKF bearing?
- CD is the 15° angular contact design with large balls. P4A is the dimensional and rotational precision class. TBTB is the four-bearing arrangement: tandem, back-to-back, tandem, back-to-back. Together they form a set for demanding spindles.
- How do I choose a replacement for an angular contact set?
- Compare bore diameter, outer diameter, width, contact angle, precision class and arrangement. The series number alone is not enough. If you have the original part number or spindle drawing, send it by WhatsApp and we help you validate the equivalence.
- What does mounting these bearings require?
- Cleanliness, shaft and housing alignment, and controlled preload. Lubrication and sealing depend on speed and environment. Respect the tightening torque and adjustment order so the rings are not deformed and precision is maintained.
