A roller bearing is any cylindrical or spherical object that helps move objects larger in size than the bearing itself. A roller bearing is a weight distribution oriented bearing. The bearing utilizes a number of contact points between circular housings containing internal rolling elements, such as ball bearings located within collars. These bearing systems use the reduction in rolling resistance as a means of increasing the efficiency of moving objects. Cylindrical roller bearings are probably one of the most familiar and common forms of roller bearings.

 

The basic design is a pair of rings with bearings. These bearings can be spherical, but are usually cylindrical. The cylinder allows the bearing to be wider than the ball bearing alone. These types of roller bearings can handle large radial loads and moderate thrusts because the loads are distributed over cylinders rather than spheres. They are typically used in applications where objects need to slide in a plane. The tapered roller bearing is similar in structure to the cylindrical roller bearing, except that the cylinder is not perpendicular to the ring, but inclined and offset. This construction has the added benefit of additional load support and the ability to spin the bearings faster.

 

They are frequently used in the automotive and heavy equipment industries. The first benefit of a tapered roller bearing is its tapered design. Each roller in the bearing can be perfectly aligned between the conical surfaces of the outer and inner rings without the need for cage guidance. This is a major development in bearing design and operation. The large end of each roller is ground so that it is at right angles to the rib on the back of the inner ring. Without the "rib" the rollers would be forced off the cage. As each roller rotates around the cone, a large area of ​​contact is created between the large end of the roller and the rib. This large area of ​​contact forces each roller to maintain precise alignment.

 

Since each roller is Universal Bearing perfectly aligned between the two raceways, the bearing works to the maximum. Each drum has an equal share of the total workload. The second benefit - the bearing's ability to support both radial and thrust loads - is the result of its internal design. Radial loads on tapered bearings produce radial and thrust reactions. Ribs constrain the rollers and counteract the load. One structural feature sets tapered roller bearings apart from most other designs: the raceways are separable. After installation, the inner ring (inner ring) and rollers are assembled as one unit, and the outer ring (outer ring) is assembled as another unit. Industry standards for size and design allow cups and cones to be interchanged if necessary.
