Angular Contact Ball B. SKF 7313 BEGAF

The SKF 7313 BEGAF angular contact ball bearing, measuring 65 × 140 × 33 mm, can accommodate high radial loads as well as axial loads in one direction.

The 7313 BEGAF angular contact ball bearing is a single-row rolling bearing from SKF, made from standard bearing steel (100Cr6), with a bore of 65 mm, an outer diameter of 140 mm and a width of 33 mm. The design features a contact angle of 40 degrees, which means that the forces are transmitted at an angle to the radial plane. A sheet steel cage maintains the correct spacing between the rolling elements. As an open bearing, this version integrates directly into the machine’s existing lubrication system.

What is the 7313 BEGAF angular contact ball bearing with a 40-degree contact angle suitable for?

This angular contact ball bearing is primarily used where combined loads consisting of radial forces and unidirectional axial forces occur. The steep contact angle of 40 degrees increases the axial load-carrying capacity in one direction. The rolling bearing is used in applications where shafts need to be guided precisely under combined loads. In the case of alternating axial forces, the component is usually supported against a second bearing.

What distinguishes the universal pairing of the BEGAF design?

The BEGAF design is a universal bearing intended for installation in pairs. If you fit two of these bearings in an O or X arrangement, the manufacturer ensures a slight preload without the need for additional shims. This simplifies assembly and results in a defined operating clearance. As this is an open roller bearing, you must provide external sealing and a lubricant supply. The component is suitable for a temperature range of -20 to +150 °C.
