Bearings are highly engineered, precision-made components that
enable machinery to move at extremely high speeds and carry 
remarkable loads with ease and efficiency.
Bearings must be able to offer high precision, reliability and durability, 
 as well as the ability to rotate at high speeds with minimal noise and vibration.
Bearings are found in applications ranging from automobiles, airplanes, computers, construction
equipment, machine tools, DVD players, refrigerators and ceiling fans.
If something twists, turns or moves, it probably has a bearing in it.
Ball Bearings

–Rolling function is provided by a ball 
–Low friction, high speed, light to medium loading 
–Light and general machine applications 

Commonly found in fans, roller blades, wheel bearings, and under hood applications on cars etc. 

Where the rolling function is provided by a cylinder of some kind.
May also be referred to as needle roller bearings (where length is 
much greater than diameter)
-Low friction, medium to heavy radial loading 
Commonly found in general machine applications including gearboxes 
and transmissions, machine tool and construction equipment.

A tapered version of a roller bearing is used for combined axial
and radial loads, such as in wheel applications on trucks 

Commonly found in heavy industrial, truck and wheel applications with

 combined radial and axial loads. Some examples are manual 
transmissions, gearboxes, power generation and other process equipment.

 A roller bearing that has a barrel shaped roller. 
- Medium friction, medium to heavy loads and misalignment capabilities 
- Generally used for very high load applications with misaligned shafts to housings. 

Commonly found in gearboxes, conveyors, pulp and paper machines and other process equipment.
