NAICS 332991 applies to Ball and Roller Bearing Manufacturing.
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 & Roller Bearings both belongs to the category of radial contact bearings.In case of ball bearings spherical balls are used however in case of roller bearings cylindrical rollers are used.due to balls used in ball bearings there is a point contact is made whether it is line contact in roller.
In 2001 U.S. establishments involved in ball and roller bearing manufacturing employed a total of more than 32,200.
This type of pump bearing: • Antifriction bearings - Single-row, deep-groove ball bearing - Double-row, angular contact ball bearing - Single-row, angular contact ball bearing pair - Cylindrical roller bearings - Spherical roller bearings - Taper roller bearings set • Sleeve bearings* • Pivoted-shoe thrust bearings*
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
Generally, a ball bearing is used when speed is important; a roller bearing is used more often when load is most important.
This industry covers establishments primarily engaged in manufacturing ball and roller bearings (including ball or roller bearing pillow block, flange, takeup cartridge, and hangar units) and parts.

Angular Contact Roller Bearing Taper Roller Bearing
That'd be rare. Ball bearings are far more common although I believe some pedals come with roller bearings.
No, the unit was set up for ball bearings. Rollers will not work. Yes you can and I just did! The races in the hub must be replaced with ones that came with new roller bearing. Inner bearing races must be removed from spindle and not used. Got the roller bearings from PartsPlace for VW in Auburn Hills, Michigan
Steel ball bearings. :)

Anti-Friction. Plain bearings have surfaces that rub together, like sleeve bearings. In roller bearings and ball bearings, the surfaces roll and do not (that is, should not) slide. If they slide they destroy themselves quickly.
A ball bearing is a stainless steel ball used in 'bearing races' to make a full bearing unit. Vet common in all machinery construction.
deep grove ball bearing is Accumulate the load 90 degree but angular contact ball bearing 25,45,Ect degree
SIC 3562 applies to BALL AND ROLLER BEARINGS.
A bearing cage is a structure which keeps the individual ball bearings or needle bearings or rollers that are part of the same "bearing" unit in approximately the correct position relative to each other. In must bearing utilising a cage, the cage does not come directly into contact with any individual ball, needle, roller, or race during use being separated by a film of grease or oil.
