Basic knowledge of bearing configuration code
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
