A roller bearing is a bearing that is often used in load-handling applications,
such as on conveyor belt rollers. In this type of bearing, the roller is a
cylinder which evenly distributes the weight of the load over a large area.
The bearing has inner and outer races, which are grooves where the balls of
the bearing rest. The race is normally formed to allow the balls to fit loosely
in the groove. These balls allow the cylinder to turn freely.
Roller bearing manufacturers offer many sizes of roller bearings, depending
on their intended use. Roller bearings may range in size from 10 millimeters
in diameter to a few feet, and they may have load-carrying capacities of thousands
of pounds.
Although roller bearings are quite popular and cost-effective, they also have
a few disadvantages. Abrasion, fatigue and pressure-induced welding of the
bearing all can contribute to a shorter life span for the bearing. It is very
important to keep the bearings properly lubricated to prolong their use.
