Angular Contact Ball B. SKF 7318 BEP

The SKF 7318 BEP angular contact ball bearing, measuring 90 × 190 × 43 mm, offers a robust solution for combined radial and axial loads.

This single-row angular contact ball bearing, type 7318 BEP, accommodates both radial and single-direction axial loads simultaneously. The design is from SKF and is made from standard rolling-element bearing steel (100Cr6). Thanks to its open design without seals, the component is suitable for applications with external sealing and lubrication. With a bore of 90 mm, an outer diameter of 190 mm and a width of 43 mm, the geometry corresponds to the dimensions of this series.

What are the practical applications of the 7318 BEP angular contact ball bearing?

This design is used for shaft mountings where axial forces in one direction act in conjunction with radial forces. As single-row angular contact ball bearings, by design, can only accommodate axial loads on one side, they are frequently mounted in pairs opposite a second bearing. Applications can be found in general mechanical and plant engineering with an externally supplied lubricant system. The open design allows for direct lubrication with lubricating oil or grease from the surrounding housing.

What is the function of the contact angle and the polyamide cage in this variant?

The contact angle of 40 degrees defines the force transmission between the inner and outer rings at an angle to the radial plane. This angle is designed to specifically accommodate unidirectional axial forces. The integrated polyamide cage guides the rolling elements evenly and contributes to low noise levels. The permissible temperature range is between –20 and +120 degrees. The bearing is manufactured to standard tolerances (P0/PN or ABEC 1) and has a standard radial clearance.
