SKF angular contact bearings are components designed to support combined radial and axial loads in a single direction. Their contact angle design allows high speeds and rigidity, so they are used in machine tool spindles, pumps, compressors and applications where precision is key. At MR Accesorios Industriales we supply them with the full designation so you can identify the exact variant your equipment needs.

The designation of this series is read in blocks. The base number, as in 71918, indicates the size and dimension series. The suffix ACDGC defines internal characteristics: contact angle, cage and preload. The slash and the code P4A indicate the precision class, in this case high dimensional and running accuracy. Therefore, when ordering a bearing from this family, it is best to provide the full code, since each suffix changes the behavior of the assembly.

They are common in milling machine, grinding machine and machining center spindles, where speed and precision are critical. They also appear in process pumps, screw compressors and gearboxes that combine loads. In Argentina, the metalworking, food and petrochemical sectors choose them for critical equipment. MR Accesorios Industriales supplies them to workshops and plants that need reliable spare parts to maintain productivity.

To select correctly, take into account the direction of the axial load and the internal clearance. These bearings are generally mounted in pairs, with preload or adjusted clearance depending on the application. Sealing and lubrication depend on the environment: a clean spindle is not the same as a pump exposed to liquids. Alignment between supports is critical; misalignment accelerates wear. Follow the manufacturer's instructions for mounting and lubrication.

Regarding equivalences, each manufacturer has its own nomenclature for precision and contact angle suffixes. There is no universal table, but a bearing with a similar designation from another brand can perform the function if dimensions, load capacity and precision class match. Always verify tolerances and clearance with the technical documentation. If in doubt, ask us and we will help you interpret the code.

To request a quote, send us the full code on WhatsApp, for example 71918 ACDGC/P4A. With that data we identify the exact variant and reply promptly. At MR Accesorios Industriales we have more than 80 years of experience in bearings and power transmission. Write to us and we will advise you with no obligation.
