The SKF 71918 ACDGC/P4A is an angular contact ball bearing built to handle combined radial and axial loads in one direction. Its contact angle provides high speed capability and rigidity, making it suitable for machine tool spindles, pumps, compressors and other precision applications. MR Industrial Accessories LLC supplies this bearing with its full designation so you can match the exact variant your equipment requires.

Reading the code helps you order correctly. The base number 71918 identifies the size and dimension series. The ACDGC block covers internal features such as contact angle, cage and preload. After the slash, P4A denotes the precision class, which in this case means high dimensional and running accuracy. Because each suffix affects how the bearing performs in the assembly, always provide the complete code when requesting a quote.

Typical uses include spindles on milling machines, grinding machines and machining centers, where speed and precision are essential. They also appear in process pumps, screw compressors and gearboxes that see combined loads. Workshops and plants rely on these bearings for critical equipment, and MR Industrial Accessories LLC serves customers across the United States and in several Latin American countries.

For proper selection, consider the direction of the axial load and the internal clearance. These bearings are often mounted in pairs, with preload or adjusted clearance depending on the application. Sealing and lubrication choices depend on the environment: a clean spindle differs from a pump exposed to liquids. Alignment between supports is critical, as misalignment accelerates wear. Follow the manufacturer's instructions for mounting and lubrication.

Equivalences can be tricky because each manufacturer uses its own suffixes for precision and contact angle. No universal table exists, but a bearing from another brand can work if dimensions, load capacity and precision class match. Always verify tolerances and clearance against technical documentation.
