For spindles and other high-precision equipment, SKF angular contact bearings with the CD/P4ADBB designation combine a 15° contact angle, P4 precision class, and a paired back-to-back arrangement with light preload. MR supplies this series to maintenance and purchasing professionals across the United States, Canada, Mexico, and South America.
The code breaks down into four elements: CD specifies the 15° contact angle and polyamide cage, P4 is the ISO precision class, A indicates a paired set, and DBB defines the back-to-back mounting with light preload. A typical part number in this series is 7005 CD/P4ADBB, where the digits denote the bore diameter.
Typical installations include machine tool spindles, milling heads, grinders, boring machines, and precision measuring systems. The bearings also appear in robotics, positioning equipment, and other machinery where combined radial and axial loads require high rigidity.
When selecting a bearing, consider the axial and radial loads, operating speed, and environmental conditions. Installation demands clean conditions, accurate alignment, and suitable lubrication. The light preload from the DBB pairing increases assembly stiffness. After mounting, verify clearances and use tools that protect the raceways.
For replacements, bearings from other manufacturers that meet the same precision and pairing specifications may be compatible, but exact dimensions and tolerances must be confirmed. The MR team can help evaluate interchange options.
