Self-aligning ball bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, inner rings with a
cylindrical or tapered bore and ball and cage assemblies. The bearings are available in open and sealed versions.

Full complement ball bearings have a filling slot in both the inner and outer ring enabling more and larger balls to be incorporated than in standard Deep Groove Ball Bearings. Filling slot bearings have a higher radial load carrying capacity than bearings without filling slots, but their axial load carrying capacity is small.
They are also unable to operate at such high speeds as bearings without filling slots. The main dimensions of BL2 design and BL3 design of NSK single  row deep groove ball bearings are identical to the  dimensions of 62 design and 63 design of the single row deep groove ball baearings. Besides open basic design, there
are also ZZ design of single row deep groove ball bearings with stainless steel shield.

NSK single row radial-Thrust ball bearings have contact angle, so these bearings are suit for carrying azial loads or combined
loads in a single direction. Usually, two or more bearings are used in duplex pairs, for the single bearing will carry the axial compound foce of the radial loads in structure. The rigidity
of the single radial-thrust ball bearings can be increased by preload. These bearings are mainly used high running accuracy spindle of the machine
tools and so on .

Self-aligning ball bearings consist of raceway of outer ring and the spherial surface whose center of curvature is identity to the
bearing center, so the inner ring, balls and cage can run freely in the bearing center, in other words it is self-aligning. They are mainly used in the drive shaft which is eaily deflexed or
difficulty aligned and so on . The smaller the contact angle is, the smaller the axial load carrying capacity is.

NSK Self-aligning ball bearings can withstand the radian between 0.07 to 0.12 when carrying normal loads.

bearings with spherical outside surface are mainly used to carry the combined loads basically on radial loads, and generally it is unfit for carrying axial loads singly. The inner
ring(including rollers and cage) and the outer ring can be mouted separately. The deflectionof bearing in relation to the housing is unallowed, for it will produced additional axial force when they
are carrying the radial load. These bearings consist of UC design, UK design, NA design,SB design, SU design,design and RB design.
