SKF E series angular contact ball bearings are ball bearings with raceways designed to support combined radial and axial loads in a single direction. Their construction allows angular contact that improves axial load capacity compared to a deep groove ball bearing. They are used in applications where shafts must be guided with precision and moderate thrust loads supported, such as pumps, compressors, gearboxes and machine tools. MR Accesorios Industriales sells this line as an official brand.

The designation of these bearings combines a six-digit basic number with the suffix E, which in the SKF series identifies an execution with optimized internal characteristics, generally associated with higher load capacity or a specific raceway design. For example, 728619 E and 729944 E are part numbers that correspond to this series. The suffix E should not be confused with other letters indicating cage, sealing or internal clearance; to correctly interpret each case, consult the manufacturer's data sheet or send us the complete part number.

These bearings are used in equipment where the shaft receives axial loads in one direction and simultaneous radial loads. They are commonly found in centrifugal pumps, screw compressors, gearboxes, machine tool spindles and industrial fans. In Argentina, the sectors that demand them most are petrochemical, food industry, mining and agricultural machinery manufacturing. Their ability to run at high speeds with good precision makes them suitable for drives requiring rigidity and reliability.

To select the correct bearing, consider the axial load it must support, the rotational speed and the type of mounting. These bearings are generally mounted in pairs, face-to-face or matched, to cover axial loads in both directions. Internal clearance and preload depend on the application: excessive clearance generates vibration and wear, while inadequate preload raises temperature. Lubrication, whether grease or oil, must be chosen according to speed and operating temperature. Alignment between shaft and housing is critical to avoid parasitic stresses.

Regarding equivalences, SKF E series angular contact ball bearings can be interchanged with products from other brands that follow the same dimensional and suffix designation, such as FAG, NSK, NTN or Timken. However, not all manufacturers use identical codes for cages, seals or clearances. Therefore, before replacing a bearing, verify the main dimensions (bore, outer diameter and width) and load conditions. If you have doubts, send us the original part number and we will help you find the equivalent reference.
