Angular Contact Ball B. SKF 7313 BECBF

The SKF 7313 BECBF angular contact ball bearing, with a 65 mm bore and an outer diameter of 140 mm, can accommodate high radial loads as well as unilateral axial loads.

The 7313 BECBF angular contact ball bearing is an open, single-row rolling bearing made from standard bearing steel (100Cr6) with a standard radial clearance. Thanks to the angularly offset raceways, the design is suitable for combined loads where radial and axial forces act simultaneously. A sheet steel cage guides the rolling elements within a temperature range of -20 to +150 degrees. This SKF rolling bearing complies with the standard tolerance class P0/PN or ABEC 1 and features an outer ring without a flange or groove.

What is the 7313 BECBF angular contact ball bearing suitable for?

This angular contact ball bearing transmits axial forces specifically in one direction, as the raceways are offset from one another in the axial direction. The 7313 BECBF design is primarily used where, in addition to radial forces, defined guiding forces in the longitudinal direction are also present. As an open bearing, the assembly can be flexibly integrated into existing oil or grease lubrication systems. When arranged in an O or X configuration, the bearing pair has minimal axial clearance, enabling play-free or precisely defined shaft guidance.

What is the significance of the 40-degree contact angle and the pairing?

The nominal contact angle of 40 degrees gives this angular contact ball bearing a high axial load-carrying capacity in the intended load direction. If the axial load acts in both directions, fit two single-row bearings facing each other. The BECBF design is factory-tuned to ensure a controlled, low axial clearance in both O and X arrangements. When installing, take the dimensions 65x140x33 mm into account and ensure the housing is properly sealed against contamination, as the open bearing does not provide any integrated protection against dirt.
