❖❖❖❖Performance Comparison of Each type of Bearing (Bore size–70mm, DB combination, L preload). The Effect of 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❖❖❖❖

Spindles with this arrangement are suited for ultra high speed operation and use position preload. They achieve higher radial and axial rigidity.❖❖❖❖

DB and DF arrangement sets can take axial loads in either direction. Since the distance of the load centers of DB bearing set is longer than that of DF bearing set, they are widely.❖❖❖❖
