1 back-to-back equipment; the rear code is DB (such as 70,000/DB); this kind of equipment is better in steel; it has good function of accepting overturning moment; the bearing can accept two-way axial load.
2 face-to-face equipment; the rear code is DF (such as 70,000/DF); the rigidity of this equipment and the ability to accept the overturning moment are not as good as the DB equipment method; the bearing can accept two-way axial load,
3 series equipment; rear code is DT (such as 70,000 / DT); this equipment can also be connected in series with three or more bearings at the same bearing; but can only accept axial load in one direction. Usually; for balance and restraint The axial displacement of the shaft; the other bearing requires the bearing to receive the axial load in the other direction.
In addition, there is a single-row angular touch ball bearing that can be easily paired. This type of bearing is specially machined; it can be combined in two back-to-back, two face-to-face or two series connection; the axial clearance of the paired combination can be selected according to requirements. The post-code CA indicates that the axial void is more moderate than the CB, and the axial void is moderate.
All-round matched bearings; can also be equipped with pre-interference bearing according to the application requirements; and later coded GA, GB, GC indicate that .GA indicates a small pre-interference after pairing, GB indicates that there is a medium pre-match after pairing Ying, GC indicates that there is a large pre-interference after pairing.
