  • Properly Preloading Tapered Roller Bearings for Roll ...

    Bearings with a tapered bore are preloaded by driving the bearing inner ring up onto its tapered seat. The resulting interference fit causes the inner ring to expand and to obtain the necessary preload. To accurately set preload, internal clearance gauges should be used.

    In this example, the bearing arrangement comprises a preloaded single row deep groove ball bearing at each end of the shaft (fig. 3). The simplest method of applying preload is to use a wave spring. The spring acts on the outer ring of one of the two bearings. This outer ring must be able to be axially displaced.

  • 7. Starting and running torques - bearing

    There are two main methods to preload a bearing. The first is solid preload, which is achieved by holding inner and outer races in place with a locking mechanism. The more common, simpler, and less expensive method is spring preload, which is achieved by using a spring to apply a constant axial load on one side.
