Angular Contact Ball B. SKF 7309 BECBP

The SKF 7309 BECBP single-row angular contact ball bearing, with a 45 mm bore and a 40-degree contact angle, provides precise guidance for combined loads.

As a single-row rolling bearing, the SKF 7309 BECBP angular contact ball bearing simultaneously accommodates radial forces and single-direction axial forces. With key dimensions of a 45 mm bore, 100 mm outside diameter and 25 mm width, this type is suitable for demanding bearing arrangements with normal radial clearance. The open component, made from standard 100Cr6 rolling-element bearing steel, is designed for use in lubricated systems. A dimensionally stable polyamide cage reliably keeps the rolling elements spaced apart and helps to ensure low operating noise during operation.

What loads can the 7309 BECBP angular contact ball bearing withstand during operation?

The design is specifically engineered to accommodate high axial forces in combination with radial forces. Thanks to the steep nominal contact angle of 40 degrees, the bearing effectively withstands unidirectional thrust forces. As a single angular contact ball bearing can only transmit axial forces in one direction, in practice it is often mounted in pairs with a complementary bearing. The Explorer version allows direct pairing in an O or X arrangement, in which a small amount of axial clearance is established as a matched bearing pair.

What properties do polyamide cages and P6/P5 tolerances offer?

The polyamide cage is characterised by its low weight and is designed for an operating temperature range of –20 to +120 degrees. It ensures smooth guidance of the rolling elements whilst minimising inertia. High running precision is ensured by dimensional accuracy to Class P6 and running accuracy to Class P5. As the outer ring has no flange or groove, the bearing can be fitted cylindrically into the surrounding housing.
