SKF offers two types of centrifugal pump cage bearings applied to petrochemical industry. Machined brass cage (m) and hammer-type steel cage (j). Using instead plastic cage bearing is strictly prohibited.

Here we elect suffix is BECBM angular contact ball bearings used in petrochemical industry of centrifugal pumps. Not just because it is less after staging the bearing internal clearance (CB) is a good control over rolling bearing with sliding and machined brass cage more sturdy than the blow pressed-steel cage design, with high working reliability. Because of this, many petrochemical companies are using the suffix BECBM bearings as they are standard.
