Ball BearingsBall bearings are the most common type of bearing by far. They are found in everything from skate boards to washing machines and PC hard drives. These bearings are capable of taking both radial and thrust loads, and are usually found in applications where the load is light to medium and is constant in nature. (ie; not shock loading) The purpose of ball bearings are to reduce rotational frictional support the radial and axial loads.
Did you know, The first radial style ball bearing was designed in 1869 by a Parisian bicycle mechanic? Thrust Ball Bearing

Roller BearingsRoller bearings are normally used in heavy duty applications such as conveyor belt rollers, where they must hold heavy radial loads. Most roller bearing has cages which reduce friction and bind by preventing the elements from rubbing against each other. There are five types of rolling elements that are used in rolling bearings. These types of rolling elements are balls, cylindrical rollers, spherical rollers, tapered rollers and needle rollers.
In roller bearings the bearing rollers are cylinders, so the contact between the inner and outer race is not a point but a line. (like the ball bearing) This spreads the load out over a large area, allowing the roller bearing to handle much greater loads than a ball bearing. However, this type of bearing cannot handle thrust loads to any significant degree. A variation of this bearing design is called the needle bearing. The needle roller bearing uses cylindrical roller with a small diameter. This allows the bearing to fit into tight places such as gear boxes that rotate at high speeds. Roller Thrust Bearing
