SKF matching single row angular contact ball 73 72 xx and xx series two kinds, and bearing standard for P6 accuracy level ( Not marked in the bearing type) , they can piece together into a back to back form or face to face, and so on. They suffix meaning: { TodayHot} B— — 40°; E— — High carrying capacity; CB/GA— — Clearance/preload SKF have three level of clearance: CB - — Standard axial clearance, paired bearing installation; CC— — The axial clearance is less than the CB. CA— — Axial clearance is less than the CCSKF also have three kinds of preload level: GA - — Light preload; GB— — Preload is greater than the GA level; GC— — Preload is greater than the GB level; Cage type: SKF offers two types of cage bearing used in centrifugal pump in petrochemical industry. Machine cutting brass cage ( In M) And blow pressure type steel cage, J) 。 Instead of plastic cage bearings is strictly prohibited. Here we chose suffix is BECBM of angular contact ball bearing used in centrifugal pump in petrochemical industry. This not only because of less bearing internal clearance after equipping ( CB level) Is a good way to control the rolling bearing inner sliding body, and machine cutting brass cage is crushing type steel cage design, has the high working reliability. Because of this, many petrochemical companies are using the suffix for BECBM bearing as their standard bearings.
