Angular contact bearings from SKF with the ACDGB/P4A designation handle combined radial and axial loads in one direction. Their design uses a specific contact angle and a polyamide cage, making them a fit for high-accuracy, high-rigidity setups such as machine tool spindles and measuring equipment. MR Industrial Accessories supplies this SKF line and can help you match the bearing to your application.

Reading the ACDGB/P4A code helps you confirm what you are ordering. The numeric prefix—7005 or 7206, for instance—sets the size and series. AC means a 25° contact angle. D tells you the cage is reinforced polyamide, and G that it is centered on the outer ring. B points to an optimized internal design. The /P4A suffix is the precision class, with tighter dimensional and running tolerances than a standard bearing. This mix is common where running accuracy matters.

You will find these bearings in machine tool spindles, milling heads, metrology equipment, precision instrumentation and positioning systems. Machine shops, automotive plants, machine tool builders and testing laboratories rely on them. Their ability to run at high speed with low friction suits assemblies that need rigidity and repeatability, like grinding machine spindles or machining centers.

When selecting a bearing, consider the axial and radial load, the rotational speed and the mounting arrangement—single, duplex or other. The ACDGB/P4A designation does not include seals, so you must plan for lubrication and protection from contaminants. The polyamide cage supports high speeds, but check that it is compatible with your lubricant and operating temperature. Proper alignment and controlled preload during mounting are essential to avoid premature failure.

For equivalents, angular contact bearings with a similar designation from other brands may work, but you must verify tolerances and contact angle, since small differences change performance. SKF is a widely recognized reference, and its part numbers are easy to cross-reference. Always check with a specialist before substituting a bearing, because interchangeability is not automatic and depends on the application.
