National Precision Bearing, Inc. Angular Contact (Thrust Type) Spherical Plain Metric Bearing

Angular contact bearings (as shown in Figure 7) are best suited for applications with single direction, thrust load. When thrust load reverses, angular contact bearing will separate. Therefore, for applications with reversing thrust load, it is necessary to use a pair of angular contact bearings. For applications requiring moment flexibility, arrange angular contact bearings in Face-to-Face or "DF" (as shown in Figure 8). For applications requiring high moment rigidity, arrange angular contact bearing in Back-to-Back or "DB" (as shown in Figure 9).
