  • Thrust Tapered Roller Bearings-Type TTHD On

    2019-6-11 · Cylindrical roller bearings also require a preload for proper operation, however, the load is applied radially instead of axially. If the bearing has a tapered bore the bearing is driven onto the taper, resulting in an interference fit. This causes the inner ring to expand and exert a radial force on the rollers to create the proper preload.
