Angular Contact Ball Bearings Combinations Available:
Anuglar contact ball bearings combinations – The lock of the angular contact ball bearing is on the outer ring.
Generally, the inner and outer rings cannot be separated, and they can bear combined radial and axial loads and axial loads in one direction.
Name and Mark of Bearing Combination:
Matched bearings consist of bearings with matching inner and outer diameters.
The first letter represents the number of matched bearings.
D: 2 pieces bearings pairing
T: 3 pieces bearings pairing
Q: 4 pieces bearings pairing
The second (or third) letter represents the arrangement in the bearing group.
DB: back to back arrangement
Feature: It can bear radial load and axial load in 2 directions.
Due to the long distance between the load center and the high rigidity of the moment load, it is easy to increase the internal load and cause damage such as peeling.
DF: face to face arrangement
Feature:
The load center distance is short, the moment load rigidity is weak, which can control the internal load increase caused by the angle error.
DT: tandem arrangement
Feature: It can bear radial load and axial load in one direction.
The axial load capacity is twice that of single row bearings. Therefore, it is suitable for the situation of large axial load in one direction.
BT: 2 or 3 bearings are arranged in parallel with another bearing to form a back-to-back arrangement
FT: 2 or 3 bearings are arranged in tendem with another bearing to form a face-to-face arrangement
DU: bearings can be arranged back to back, face to face, or in tendem
Pls note that U stands for universal matching bearing.
Universal matching bearings can be arranged arbitrarily without performance loss.
