Many bearings are used in pairs. Because of the need to support the shaft, the support at both ends is better. When the shaft rotates during operation, the inner rings of the bearings installed at both ends of the shaft rotate together with the shaft (synchronized rotation), so that the shaft wears very little and rotates briskly. This puts forward requirements for the assembly and the manufacture of the shaft, requiring the bearing and the shaft to be assembled on the same axis, and there is an additional load when the assembly is misaligned, which affects the normal operation of the shaft. The following introduces some basic common sense of bearing configuration code, which may be helpful to you.
Number code in the bearing arrangement group
/D--two sets of bearings
/T--three sets of bearings< /p>
/Q--four sets of bearings
/P--five sets of bearings
/S--six sets of bearings
bearing configuration Arrangement code in group
B--back to back
F--face to face
T--tandem
BT--back to back and Tandem
FT--face to face and tandem
BC--back-to-back in tandem in pairs
FC--face in tandem in pairs
Example:
7210C/DB paired back-to-back installation
32208/DF paired face-to-face installation
7210C/DT paired Tandem installation
7210C/TBT three sets configuration, two sets in series and one set back to back
7210C/TFT three sets configuration, two sets in series and one set face to face
3 sets of 7210C/TT configurations, in series
4 sets of 7210C/QBC configurations, back-to-back in pairs in series
4 configurations in 7210C/QFC in series, face-to-face in pairs
7210C/QT in four configurations, in series
7210C/QBC in four configurations, three in series and one in back-to-back
7210C/TBT in three configurations, two in series And one set back to back
7210C/TFT three sets configuration, two sets in series and one set face to face
7210C/TT three sets configuration, in series
7210C/QBC Four configurations, back-to-back in pairs
7210C/QFC four configurations, face-to-face in pairs
7210C/QT four configurations, in series
7210C/QBC four configurations, three in series and one back to back
7210C/QFT four configurations, three in series and one face to face
