Detailed Product Description
DWCF production of angular contact ball bearings can be broadly classified into four types:
Single row angular contact ball bearings
7000C, 7000AC, 7000A, 7000B
Group supporting contact ball bearing
Face-to-face (DB), back-to-back (DF), tandem (DT), triple
Double row angular contact ball bearings
Inner Ring Road dual-roll and the two outer ring raceway combination of single -
Outer Ring Road dual-roll and the two inner ring raceway combination of single -
Double Raceway Road, outer and inner two-roll mix
Four-point contact ball bearing
QJ0000, QJF0000
Single row angular contact ball bearings and ball bearing contact group supporting
In order to improve the angular contact ball bearing rigidity and load-bearing capacity, the same specifications of the angular contact ball bearing is often to double-(DB, DF, DT), triple (TBT, TFT, TT), quadruple (QBC, QFC, QT) even Wulian (PBC, PFC, PT, PBT, PFT), such as group distribution. Of duplex angular contact ball bearings, and its sub-group with back-to-back manner (DB), face-to-face (DF), and tandem (DT) in three. Supporting back-to-back group for contact ball bearing under a separate or combined radial and axial load, to be capable of sustaining a two-way axial load. Can withstand a greater overturning moment, there are strong stiffness. Working conditions can be imposed in accordance with the use of different pre-load. Group face-to-face with the angular contact ball bearings bear smaller overturning moment, the system provides a lower stiffness. The advantage lies in bearing lower coaxiality error sensitive. Group series with the angular contact ball bearing in one direction only allowed to bear a larger axial load. In most cases necessary to impose pre-load spring, can bear the radial load bearing size and the stiffness depends on the value of the selected pre-load.
Divided into groups with pre-load bearing (pre-load) and pre-clearance (pre-clearance) in two ways.
Pre-load: GA - light pre-load
GB - Pre-load
GC - re-pre-load
Pre-clearance: CA - smaller axial clearance
CB - Medium Axial Clearance
CC - larger axial clearance
