Common roller bearing use cylinders of slightly greater length than diameter. Roller bearing typically has high radial load capacity than ball bearing, but a low axial capacity and higher friction under axial loads. If the inner and outer races are misaligned, the bearing capacity often drops quickly compared to either a ball bearing or a spherical roller bearing.
Roller bearing is the earliest known type of rolling-element-bearing, dating back to at least 40 BC. A roller bearing carries a load by placing round elements between the two pieces. Rolling bearing has the advantage of a good tradeoff between cost, size, weight, carrying capacity, durability, accuracy, friction, and so on. 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.
