  • Tapered Roller Bearings Selection Guide |

    2021-3-4 · BEARING SETTING With tapered roller bearings, the term “setting” simply indicates the speciic amount of end play (axial clearance) or preload (axial interference) within a mounted bearing. The lexibility to easily adjust and optimize setting at the time of assembly is an inherent advantage of tapered roller bearings.

    The simplest example of a flat sliding bearing is the circular or rectangular single-recess pad shown in Figure 1.6. However, a single flat pad must always be held down by a positive force. Where the applied load reverses in direction, as in some machine-tool slideway systems, opposed pads are employed.
