Tapered roller bearings are a unique subset of axial roller bearings in which the rollers are tapered rather than straight right cylindrical. The roller shape allows thrust loads to be withstood in addition to the radial loads. A familiar application for tapered roller bearings is the central hub bearings for automobile wheels. When an auto traverses a turn, the wheels must withstand a significant lateral force, so that tapered roller bearings are necessary. Tapered roller bearings have an intriguing geometry. If all rolling-contact surfaces are projected out to form cones, all cone tips converge at a single point on the central axis of the bearing. This fact enabled early machine designers to have tapered bearings fabricated without CNC equipment. The following two figures show how tapered roller bearing geometry is derived. Note how it is intuitive how the full cones roll about one another. Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial ) load.

In spherical roller thrust bearings the load is transmitted from one raceway to the other at an angle to the bearing axis. The bearings are therefore suitable for the accommodation of radial loads in addition to simultaneously acting axial loads. Another important characteristic of spherical roller thrust bearings is their self- Aligning capability. This makes the bearings insensitive to shaft deflection and misalignment of the shaft relative to the housing. Spherical roller thrust bearings incorporate a large number of asymmetrical rollers and have specially designed raceways with an optimum conformity. They can therefore support very heavy axial loads and permit relatively high speed operation. When low- Carbon, Carburized grades of steel are used, Carbon is introduced after the spherical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, Fatigue- Resistant case and a tough, Ductile core. Spherical roller thrust bearings are produced in two designs depending on the size and series. Bearings up to and including size 68 identified by the designation suffix E have a pressed steel window- Type cage, Which, With the rollers, Forms a non- Separable assembly with the shaft washer. All other bearings have a machined brass or steel cage which is guided by a sleeve held in the shaft washer bore. The shaft washer and cage with rollers form a non- Separable unit.
