SKF angular contact bearings with the CD/P4ADGB designation are supplied as a matched pair, ready for precision spindle applications. This assembly combines a 15° contact angle, P4 running accuracy and a light preload in a back-to-back arrangement. MR Industrial Accessories provides this line and assists in matching the correct set to your equipment.
Reading the code helps when ordering. CD refers to the angular contact design with a 15° contact angle and a polyamide cage. P4 is the dimensional and rotational precision class, equivalent to ABEC 7. ADGB covers the matching: two bearings universally mounted, light preload, back-to-back. The leading digits give series and size: 70 for the medium section, 719 for the thin section. The GB suffix affects preload and matching only, not dimensions.
These bearings suit milling, grinding and machining center spindles where axial stiffness and rotational accuracy matter. They also appear in boring heads, precision rotary tables and measuring equipment. The matched pair supports axial loads in both directions while keeping the shaft concentric. Typical settings include metalworking shops, auto parts plants and machine tool builders.
Selection starts with preload. GB is light, but other variants exist for different rigidity needs. During mounting, work in a clean environment, align the support faces and apply the correct lubricant, usually high-speed grease or oil. After assembly, check axial clearance; over-tightening speeds up wear. The polyamide cage has a temperature limit of 120 °C, so monitor operating heat. For high-speed shafts, consider cooling the assembly.
SKF bearings with this designation interchange with other makers that offer the same P4 precision and universal matching. When you request a quote, include the full part number and the equipment brand. If the exact number is not available, we can suggest an alternative with equivalent characteristics. Interchangeability depends on precision, contact angle and matching type, not just dimensions.

Frequently asked questions
- What does the CD/P4ADGB designation mean?
- CD indicates a 15° angular contact design with a polyamide cage; P4 is the precision class equivalent to ABEC 7; ADGB defines two universally matched bearings with light preload and a back-to-back arrangement. The complete code also includes series and size.
- Can these bearings be mounted individually?
- No, they are designed as a matched set. Mounting them separately changes the preload and precision. If you need a single bearing, ask us about another designation from the same series.
- What lubrication do you recommend?
- It depends on speed and temperature. For high revolutions, use high-speed grease or circulating oil. The polyamide cage limits temperature to 120 °C. Contact us with your application details.
