SKF angular contact bearings handle combined radial and axial loads acting in one direction. Their contact angle provides the rigidity and speed capacity needed in machine tool spindles, pumps and compressors. MR Industrial Accessories LLC supplies these bearings to customers across the United States and Latin America.
Reading the designation helps you specify the right bearing. The base number sets the size; ACD denotes the contact angle and internal design; HC means ceramic balls; P4A is the precision class. Examples in this series include 7013 ACD/HCP4A and 71920 ACD/HCP4A. Recognizing each suffix avoids ordering the wrong variant.
Typical installations are milling, grinding and machining center spindles, plus high-pressure pumps, screw compressors and transmission equipment. Maintenance teams in automotive, metalworking and food processing plants rely on them where speed and accuracy matter. MR Industrial Accessories LLC ships throughout the United States and to several Latin American countries.
Selection depends on axial and radial load, rotational speed and operating environment. Mounting calls for clean conditions, correct alignment and proper lubrication; back-to-back or face-to-face pairs are common. Sealing and internal clearance also affect results. Review the technical data before installation.
SKF angular contact bearings can interchange with other recognized brands when dimensions, contact angle and precision class align. Tolerances and internal design still need checking, since small differences change behavior. For replacements, compare full designations and ask a specialist.

Frequently asked questions
- What does ACD/HCP4A mean in an SKF bearing?
- ACD is the 25° contact angle and optimized design; HC indicates ceramic balls; P4A is the high-speed precision class. These suffixes define key characteristics for demanding applications.
- When should I choose an angular contact bearing over a radial one?
- When axial loads combine with radial loads, or when high precision and speed are required. Angular contact bearings handle these conditions in one direction.
- How are these bearings correctly mounted?
- With precise alignment, rigorous cleanliness and adequate lubrication. They are frequently used in pairs with preload. Follow the manufacturer's instructions and consult a specialist if you have doubts.
