One of the many bearings that are often used for many mechanical purposes and are often considered to be pretty durable and strong are roller bearings. One particular roller bearing that seems to be favored when it comes to large thrust loads and large radial loads is the tapered roller bearing. Tapered roller bearings are often used in cars, trucks and other vehicles due to the ability of these bearings to easily cope with the vertical and horizontal forces that are present simultaneously in these applications.

These bearings are made with the use of conical rollers that are encased in conical races. These tapered roller bearings are often used for the wheel bearings of cars and trucks and this is due to the capability of these bearings to carry higher loads due to the greater contact area that they have as compared to ball bearings. One of the downsides seen with the use of these roller bearings is the cost of making them which then reflects on the cost of buying them. This is said to be due to the complexities involved in manufacturing them.

Another problem seen with these kinds of roller bearings is the possibility of the bearings ejecting the rollers in them when they are used on extremely heavy loads. This is due to the wedge-like shape of these bearings. Another problem also seen with these kinds of bearings is the higher bearing friction present in these things as compared to their ball bearing counterparts. This is usually due to the forces that are placed on these bearings and the wider area of the spherical roller bearings inside the collar.
