                                                                                                                                      Applications :      Ball bearings are manufactured to a very high precision level in high volume quantities . Ball bearings are used primarily to  support rotating shafts in mechanical   equipment.  They can be found in everything from personal computers to  passenger cars. They are of simple design and can be precision made in mass   production quantities. They can support heavy loads over a wide speed range   and do it virtually friction free.  They come in many different sizes and   shapes, are relatively inexpensive, and require little or no maintenance. They have predictable design lives and operating characteristics and are truly a valuable asset to the rotating equipment industry of today.
