Typical rolling-element bearings range in size from

Other bearing designs are often better on one specific attribute, but worse in most other attributes, although fluid bearings can sometimes simultaneously outperform on carrying capacity, durability, accuracy, friction, rotation rate and sometimes cost.
There are five types of rolling elements that are used in rolling-element sliding bearing bearings: balls, cylindrical rollers, spherical rollers, tapered rollers, and needle rollers.Rolling-element bearings have the advantage of a good tradeoff between cost, size, weight, carrying capacity, durability, accuracy, friction, and so on. The cages reduce friction, wear, and bind tilting pad bearing by preventing the elements from rubbing against each other.

Typical rolling-element bearings range in size from 10 mm diameter to a few metres diameter, and have load-carrying capacity from a few tens of grams to many thousands of tonnes.

Most rolling-element bearings feature cages. Only plain bearings are used as widely as motor bearingrolling-element bearings.. Caged roller bearings were invented by John Harrison in the mid-18th century as part of his work on chronometers
