Angular contact ball bearings in the SKF E series are built with raceways that handle radial and axial loads acting together in one direction. The angular contact design gives them more axial capacity than a deep groove ball bearing. They suit shafts that need precise guidance while carrying moderate thrust, as seen in pumps, compressors, gearboxes and machine tools. MR Industrial Accessories supplies this line.

Part numbers in this series use a six-digit basic number followed by the suffix E. In the SKF range, that suffix points to an optimized internal execution, often tied to a particular raceway design or load capacity. Examples include 728619 E and 729944 E. Do not read E as a cage, seal or clearance code; those use other letters. Check the manufacturer data sheet or send the full part number so we can confirm the meaning for your case.

These bearings appear where a shaft takes axial load in one direction along with radial load at the same time. Typical equipment includes centrifugal pumps, screw compressors, gearboxes, machine tool spindles and industrial fans. Petrochemical, food processing, mining and agricultural machinery operations rely on them. Their ability to run at high speed with good precision makes them a fit for drives that demand rigidity and dependable operation.

Selection depends on the axial load to be carried, the rotation speed and the mounting arrangement. Because these bearings take axial load in one direction only, they are usually installed in face-to-face or matched pairs to cover both directions. Clearance and preload must match the application: too much clearance brings vibration and wear, while incorrect preload raises temperature. Grease or oil lubrication follows speed and working temperature. Shaft-to-housing alignment also matters to prevent parasitic stresses.

For interchange, SKF E series angular contact bearings can be replaced by products from other makers that share the same dimensions and suffix designation, such as FAG, NSK, NTN or Timken. Codes for cages, seals and clearances are not identical across all manufacturers. Before substituting a bearing, confirm bore, outer diameter and width, and review the load conditions. If anything is unclear, send the original part number and we will help identify the equivalent reference.
