DESIGN, TYPES, AND FEATURES

SINGLE-ROW ANGULAR CONTACT BALL BEARINGS

Since these bearings have a contact angle, they can sustain significant axialloads in one direction together with radial loads. Because of their design, whena radial load is applied, an axial force component is produced; therefore, twoopposed bearings or a combination of more than two must be used.

Since the rigidity of single-row angular contact ball bearings can beincreased by preloading, they are often used in the main spindles of machinetools, for which high running accuracy is required. (Refer to Chapter 10,Preload, Page A96).

Usually, the cages for angular contact ball bearings with a contact angle of30 (Symbol A) or 40(Symbol B) are in accordance with Table 1,butdepending on the application, machined synthetic resin cages or moldedpolyamide resin cages are also used. The basic load ratings given in thebearing tables are based on the cage classification listed in Table 1.

Though the figures in the bearing tables (Pages B50 to B61; bearing borediameters of 10 to 120) show bearings with single-shoulder-type inner rings,both-shoulder-type bearings are also available. Please consult NSK for moredetailed information.

In addition, for bearings with the same serial number, if the type of cagesare different, the number of balls may also be different. In such a case, the

load rating will differ from the one listed in the bearing tables.Angular Contact Ball Bearings with contact angles of 15 (Symbol C) and

25 (Symbol A5) are primarily for high precision or high speed applications,and machined brass or synthetic resin cages or molded polyamide cages areused.

The maximum operating temperature of molded polyamide cages is 120C.

SELF-ALIGNING BALL BEARINGS

SELF-ALIGNING BALL BEARINGS Bore Diameter 5~110mmPages B74~B79

DESIGN, TYPES, AND FEATURES

The outer ring has a spherical raceway and its center of curvaturecoincides with that of the bearing; therefore, the axis of the inner ring, ballsand cage can deflect to some extent around the bearing center. This type isrecommended when the alignment of the shaft and housing is difficult andwhen the shaft may bend. Since the contact angle is small, the axial loadcapacity is low.

Pressed steel cages are usually used.

PROTRUSION AMOUNT OF BALLS

Among self-aligning ball bearings, there are some in which the ballsprotrude from the side face as shown below. This protrusion amount b1 islisted in the following table.

INTERNAL CLEARANCETable 9.12 (Page A90)

PERMISSIBLE MISALIGNMENT

The permissible misalignment of self-aligning ball bearings isapproximately 0.07 to 0.12 radian (4 to 7) under normal loads. However,depending on the surrounding structure, such an angle may not bepossible. Use care in the structural design.
