SKF single row angular contact ball bearing pairing

SKF single row angular contact ball have matched 72XX and 73XX series two kinds, and bearings standard precision for the bearing type at the level (in), they can not marked arbitrary matched stack into back-to-back form or face-to-face form etc. They suffix meaning: {TodayHot}

B -- 40 °; E - high bearing capacity; CB/GA - clearance/pre load

SKF has 3 kinds clearance level:

CB - standard axial gap, the matchmaking bearing installation;

CC - less than the CB axial clearance;

CA - axial clearance less than CC

SKF also have 3 kinds of pre load level:

GA - light pre load;

GB -- -- -- the load than GA ranks;

GC -- -- -- the load than GB ranks;

Keep frame type:

SKF provide two types maintains a bearing used in petrochemical industrial centrifugal pump. Machine cutting brass keep rack (use maroleng says) and strike pressure type steel cage (with J says). Instead of plastic maintains a bearing will use is forbidden.

Here we elected suffix is the Angular contact ball bearing BECBM applied to petrochemical industrial centrifugal pump. This is not only because the bearing less matched stack internal clearance (CB level) can be a very good control of sliding roller bearings, and machine cutting brass keep frame a strike pressure type steel maintains a design more solid, has high reliability. Because of this, many petrochemical company is used for the bearing BECBM suffixes as their bearings.
