Paired Spindle Bearings

With rigid bearing preload, adjusted bearing pairs in back-to-back, face-to-face or tandem arrangement offer an effective, economic and technical solution for a variety of applications.

Back-to-back arrangement (DB)

The contact lines form an O. The back-to-back arrangement is distinguished by a broad support base and high rigidity against tilting moments. The axial force is absorbed in both directions.

Face-to-face arrangement (DF)

The pressure lines form an X. This bearing arrangement is less sensitive to misalignment than the back-to-back arrangement, but does however, have less tilting rigidity. The axial force is absorbed in both directions.

Tandem arrangement (DT)

In this bearing arrangement, the contact lines are arranged in parallel. The axial load capacity is twice that of a single bearing, but only in one direction. That is why this bearing pair must be adjusted against another bearing or bearing pair.

Universal Design (U)

Universal bearings can be paired in any arrangement listed above. It must be noted here that the bearings require the same preload.
