Angular Contact Ball B. SKF 7322 BECBM
The SKF 7322 BECBM angular contact ball bearing, with a bore of 110 mm, can accommodate high combined radial and axial loads at operating temperatures of up to +200 degrees.
The 7322 BECBM angular contact ball bearing combines a bore of 110 mm, an outside diameter of 240 mm and a width of 50 mm. As a single-row rolling bearing made from standard bearing steel (100Cr6), it supports rotating shafts under high loads. The open design without an integrated seal allows operation in lubricated housings at temperatures ranging from –20 to +200 degrees. Design engineers prefer to use this Explorer version where both radial loads and unilateral axial forces act on the bearing location simultaneously.
What is the 7322 BECBM angular contact ball bearing suitable for in operation?
This rolling bearing is suitable for industrial applications involving rotating shafts where strong axial forces occur on one side. Thanks to its 40-degree contact angle, the bearing effectively supports axial loads together with radial forces. In many systems, maintenance engineers fit two of these bearings in a mirror-image configuration to accommodate opposing axial thrusts. The brass cage guides the rolling elements with minimal vibration, which helps to extend service life under continuous load. The open design also facilitates the supply of lubricant directly from the housing system.
What do the tolerance classes P6/P5 and ‘universal pairing’ mean?
The tolerance class combines dimensional accuracy to P6 with increased running accuracy to P5, which promotes low-vibration and smooth running. When fitted in pairs in an O or X arrangement, the bearing pair has a low axial clearance. This feature makes it easier for you to set the bearing clearance precisely within the housing. When designing the assembly, ensure that the 100Cr6 steel is properly lubricated, as the open bearing has no built-in protection against contamination. Always check the specified load direction along the pressure angle before installation.
What are the main dimensions of the 7322 BECBM angular contact ball bearing?
This single-row bearing has an inside diameter of 110 mm, an outside diameter of 240 mm and a width of 50 mm. The outer ring is designed without a flange or groove. These dimensions allow the component to be fitted precisely into suitable bearing housings and onto cylindrical shaft seats.
What is the purpose of the 40-degree pressure angle?
A contact angle of 40 degrees transmits forces obliquely to the radial plane through the rolling elements. As a result, the angular contact ball bearing can accommodate not only radial forces but also high unilateral axial forces. The steeper the contact angle is designed, the higher the axial load-carrying capacity of the bearing arrangement in that direction.
What are the key features of the BECBM design from SKF?
The designation BECBM stands for an optimised internal design with a 40-degree pressure angle and a solid brass cage. Furthermore, the bearing is designed for universal installation in sets: when fitted as a pair in an O or X configuration, a small amount of axial play is automatically established.
What is the permissible temperature range for the bearing?
The bearing, made from standard roller bearing steel (100Cr6) with a brass cage, is designed for operating temperatures ranging from -20 to +200 degrees. As no elastic sealing elements are fitted, these components do not impose any thermal limitations. The temperature resistance of the lubricant used in the housing is crucial for safe operation.
What are the advantages of tolerance classes P6 and P5?
The combination of dimensional accuracy to P6 and running accuracy to P5 reduces both radial and axial deviations from the standard tolerance. This promotes smooth running at high speeds, reduces vibrations in precision applications and enables highly accurate shaft guidance.
How is the open angular contact ball bearing lubricated?
As this bearing is of an open design, the bearing housing requires external sealing to protect the machine casing from dirt and moisture. Lubricating oil or roller bearing grease is supplied directly through the casing. The open design allows the lubricant direct access to the raceways and the brass cage.
