Angular Contact Ball B. SKF 7204 BEP

The SKF 7204 BEP angular contact ball bearing, with dimensions of 20 × 47 × 14 mm and a 40-degree contact angle, accommodates single-direction axial loads as well as radial forces.

The 7204 BEP angular contact ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with a bore of 20 mm, an outer diameter of 47 mm and a width of 14 mm. The manufacturer, SKF, produces this version with standard radial clearance in tolerance class P0/PN (ABEC 1). Designed as an open bearing without an integrated seal, this design allows direct contact with the lubricant in the housing. Due to the asymmetrical design of the raceways, the bearing transmits unidirectional axial forces, together with radial forces, to the shaft.

What is the 7204 BEP angular contact ball bearing suitable for in operation?

This angular contact ball bearing is suitable for designs in which radial forces and single-direction axial loads occur in combination. As single-row angular contact ball bearings, by design, can only accommodate axial forces in one direction, they are usually mounted opposite a second bearing or within matched bearing sets. To ensure reliable operation, the permissible temperature range is specified as -20 to +120 degrees.

What advantages do the polyamide cage and 40-degree contact angle offer in the 7204 BEP?

The 40-degree contact angle supports a high axial load-carrying capacity in the direction of the load. The integrated polyamide cage is characterised by its low weight and vibration-damping running characteristics. As this is an open bearing without its own seal, the lubricant and external housing seal are selected to suit the ambient conditions. The cylindrical outer ring is designed without a flange or groove, which facilitates installation in smooth housing bores.
