Angular Contact Ball B. SKF 7301 BEP

The SKF 7301 BEP single-row angular contact ball bearing, measuring 12x37x12 mm, accommodates combined radial loads and unilateral axial loads.

The SKF 7301 BEP angular contact ball bearing is an open rolling bearing made from standard bearing steel (100Cr6). Its design transmits forces at a contact angle of 40 degrees, obliquely to the radial plane. Installation is recommended when, in addition to radial forces, axial loads in one direction are acting on the shaft simultaneously. With a bore of 12 mm, an outside diameter of 37 mm and a width of 12 mm, the unit offers compact mounting dimensions for industrial bearing arrangements.

What is the 7301 BEP angular contact ball bearing suitable for in operation?

This single-row bearing is suitable for shaft mountings that carry radial forces together with axial forces acting in one direction. Relevant fields of application include systems with defined axial preload. As single-row angular contact ball bearings can only accommodate axial forces in one direction, designs usually incorporate a second bearing as a counter-bearing. The lightweight polyamide cage guides the rolling elements precisely and ensures smooth operation within a temperature range of -20 to +120 degrees.

What is the function of the 40-degree contact angle in this rolling bearing?

The contact angle of 40 degrees determines the force transmission between the inner and outer rings. Compared with bearings with a smaller angle, this geometry supports higher axial loads whilst minimising axial deformation. When installing the bearing, please note that the open bearing has no integrated seals. External sealing and lubrication with oil or grease are required. The tolerance class P0/PN (ABEC 1) and the standard radial bearing clearance ensure a precise fit for standard fits.
