The main requirements for bearing arrangements are excellent speed suitability, stiffness and precise guidance of the work spindle. The spindle bearing set FAG B7017C.T.P4S.DTL is connected in series at the working end. On the drive end, a spindle bearing set FAG B71917C.T.P4S.DTL in series configuration is used. The bearings are light preloaded (UL) with improved accuracy (P4S). This configuration has no floating bearing and is a rigid positioning bearing system. The two sets of bearings together form an O-shaped configuration. FAG machining center lathe spindle FAG bearing selection The bearings must guide the spindle precisely and radially and axially, and the stiffness is high, which is achieved by choosing the largest possible shaft diameter and the proper bearing configuration. These bearings are preloaded and have improved accuracy. The spindle bearing set FAG B7018E.T.P4S.TBTL is installed as a locating bearing at the working end with a light preload series-O configuration. Install a single row cylindrical roller bearing FAG N1016K.M1.SP as a floating bearing on the drive end. This bearing configuration is suitable for high speeds and high cutting power.
