Decoding SKF 7004 CD/P4ADFB
- 70Series
- Angular contact ball bearings, 70 series. Series differ in outside diameter and width even when the bore is the same.
- 04Bore
- Bore 20 mm (04 × 5).
- CD/P4ADFBSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7004 is the standard ISO basic designation, which sets the bearing type, series and bore.

SKF angular contact bearings handle radial and axial loads in a single direction. The raceways are offset, so the balls contact them at an angle. That geometry gives these bearings more axial capacity than a standard deep groove ball bearing. Machine tool spindles, pumps, compressors and gearboxes rely on them where accuracy and rigidity matter.
Reading the code tells you what you are holding. Take 7004 CD/P4ADFB: 70 series, ultra-light section, CD for a 15° contact angle, P4 for the dimensional and running precision class, and ADFB for a pre-assembled pair with preload and a defined arrangement. Suffixes like these decide whether a replacement will work, so check them before ordering.
Contact angle drives the trade-off. A wider angle carries more axial load but lowers the limiting speed. Seals may be open or shielded, depending on where the bearing runs. Grease suits most high-speed duties; oil is used in severe conditions. Mounting calls for precise alignment and control of axial clearance, particularly with matched sets, and preload must follow the manufacturer's specification to avoid overloading.
These bearings appear in milling, grinding and machining center spindles, in high-pressure pumps and screw compressors, and in gearboxes and transmission equipment that see combined radial and axial forces. Their speed capability also fits high-frequency motor applications and lathe chucks.
SKF angular contact bearings interchange with other European and American brands built to the same design and precision standards, provided the main dimensions, contact angle and precision class line up. Arrangement suffixes such as DB, DF and DT set tandem or face-to-face mounting and must be kept. Never mix precision classes in one set.

Frequently asked questions
- What does the CD suffix mean on an SKF bearing?
- CD indicates a 15° contact angle and a window-type polyamide cage. It sets the axial load capacity and the limiting speed, so keep the same designation when replacing a bearing.
- How is a matched angular contact bearing mounted?
- Align the bearings according to the arrangement given by the suffix (DB, DF, DT). Control preload and axial clearance with measuring instruments. Poor alignment leads to overheating and early failure.
- What is the difference between a deep groove ball bearing and an angular contact bearing?
- An angular contact bearing has offset raceways, so it supports axial loads in one direction and combined loads. A deep groove ball bearing mainly takes radial loads. Where axial thrust is significant, the angular contact type is the right choice.
