Taper Roller Bearings, Material : Chrome Steel

Taper roller bearings use conical rollers that run on conical races. Most roller bearings only take radial loads, but tapered roller bearings support both radial and axial loads, and generally can carry higher loads than ball bearings due to greater contact area. Taper roller bearings are used, for example, as the wheel bearings of most cars, trucks, buses, and so on. The downsides to this bearing is that due to manufacturing complexities, tapered roller bearings are usually more expensive than ball bearings; and additionally under heavy loads the tapered roller is like a wedge and bearing loads tend to try to eject the roller; the force from the collar which keeps the roller in the bearing adds to bearing friction compared to ball bearings.

Tapered Roller Bearings consist of two main units. A cup and a cone. The cup is on the

outer race whereas the cone consists of the inner race. The tapered rollers are guided by the high load on the inner race.

These bearings are capable of carrying both the radial and axial loads and permit fine adjustment for end play.
