Want this question answered?
there are many types of bearings .... 1)ball bearing 2)roller bearing 3)ball thrust bearing 4)roller thrust bearing & 5)tapered roller thrust..
Ball bearings are a rolling device that helps reduce friction with rolling apparatus with a ball and enables smooth movement. There are basically two types of ball bearings; radial and thrust. A radial is a pulley that is handles by tension, while a thrust type puts stress on the bearing to put weight on the load.
Spherical bearings are round (ball bearings) while cylindrical bearings are in the shape of elongated rods.

AnswerYou will have to do some research. number of manufacturers and their production levels. example: Timken Bearing: produced 2.5 billion ball bearings in 1998. : Stats are their are 80%-90% still in service and those not are in junk yards.You have a lot of work ahead of you if you really need to know this answer.It depends on bearing qualities the manufacturing of bearings depends on demand. the different varieties are-Taper Roller Bearings, Deep Groove Ball Bearings, Cylindrical Roller Bearings, Spherical Roller Bearings, Spherical Thrust Bearings, Clutch Release Bearings, Needle Roller Bearing, Self Aligning Ball Bearings, Angular Contact and Double Row Bearings, King Pin Bearings, UCP Pillow Block, Water Pump Bearing, Ball Bearing Manufacturers, Metal Bearing exporters, Roller Bearing, Needle Bearings, Automotive, Roller High Precision Manufacturers, THRUST BALL BEARING, Automobile Bearing, Thrust Bearing, Roller Bearing Cylindrical Manufacturers, Needle Bearing Cages Manufacturers, Engine Bearings Manufacturers, Elevator Part Bearing Hanger ManufacturersVisit Us At http://www.arb-bearings.com

The bearings on the end of piston rods, connecting them to the crankshaft are 'thrust' bearings, on some cars the end of the crankshaft, where it comes out of the front that the harmonic balancer aka crank pulley is on use a ball bearing. Components driven by the serpentine belt, or in older cars V-belts, like the alternator use sealed roller or ball bearings
copper losses Comment: Advantages: Their operation is silent They have a high efficiency They are relatively safe Disadvantages Expensive Copper losses and hysteress losses
Faulty ball bearings lead to bearing failure.
Ball bearings are polished by using an abrasive cloth. Before the bearings can be polished, the polishing paste must first be applied to the ball bearing.
If you need replacements, they can be bought at a hardware store. If you mean applications/uses ... bicycle wheels have ball bearings. Lots of rolling objects that move around an axle have either needle bearings or ball bearings or roller bearings.
