681xzz ball bearing  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. 

• riction coefficient, low energy consumption, high mechanical efficiency;
• Dimension has been standardized, interchangeable, installation, removal and maintenance of a repair is very convenient;
• axially compact axial dimension of the machine greatly reduced;
• igh precision, wear, long life, and can guarantee a longer period of time a holding shaft mounting accuracy;
•  with self-aligning bearing characteristics, there is a slight deflection or when the spindle engaging member with a different mind still work;
• suitable for specialized mass production, quality, reliability, producing a high efficiency, low cost;
