SKF paired single-row angular touch ball bearings are available in 72XX and 73XX series; and the bearing specification accuracy is P6 (not marked in the bearing type); they can be assembled in a back-to-back or face-to-face manner. Their suffix meaning:
B 40°,
E high carrying capacity,
CB/GA void/preload SKF has 3 void levels.
CB specification axial clearance; mating bearing assembly,
CC axial clearance is less than CB,
CA axial clearance is less than CC
SKF also has three preload levels:
GA light preload,
GB preload is greater than GA grade,
The GC preload is greater than the GB rating.
Cage type:
SKF supplies two types of cage bearings for use in petrochemical industrial centrifugal pumps. Machined brass cages (indicated by M) and crushed steel cages (indicated by J). In contrast plastic cage bearings are prohibited.
Here we choose the suffix BECBM angular touch ball bearings used in petrochemical industrial centrifugal pumps. This is not only due to the less internal bearing clearance (CB level) after assembly, which can well control the bearing inner rolling body sliding; The machined brass cage is more solid than the stamped steel cage; it has high operational reliability. Because of this; many petrochemical companies are using bearings with the suffix BECBM as their specification bearings.
