Performance Comparison of Each Type of Bearing (bore size 70 mm, DB combination, L preload). Preload affects performance of ACBBs in much the same way that the contact angle does. As preload increases, the rigidity increases but the speed capability decreases. NSK has defined standard preload levels as Extra

(Code: DB). Face-to-face duplex arrangement. (Code: DF). Notes: 1. Since the bearings are manufactured in a set to adjust for the internal clearance or pre-loading, parts with same serial number must be used for assembly. 2. Combination of more than 3 bearings may occur. Please consult NTN Engineering for details.

DF and DB duplex bearings are capable of taking radial loads and axial loads in either direction. Type DT is used when there is a strong axial load in one direction and it is necessary to impose the load equally on each bearing. Duplex Bearings.
