6219 zz 6219 2rs 6219 Deep Groove Ball Bearings 6000 seris bearing no noise

Product Description:

Specification:

Deep groove ball beaings composed of four basic parts: Inner ring, outer ring, ball and cage. In normal operation cases, inner raceway, outer raceway and ball mainly bear load, and the cage separate and maintain a stable effect for ball. 

Product Features:

Deep groove ball bearing belong non-separable bearings and structure is simple, easy to use,  Mainly used to support radial load, also can bear a certain amount of thrust load. Increase the bearing radial clearance, has the heart to the nature of the thrust bearing, can bear the larger axial load. This kind of bearing can limit the two directions of the axial movement. According to the size of the clearance allows inner and outer relative tilt 8 '~ 16'. 

Product Application: 

Deep groove ball bearings the most widely used in mechanical industry.     Such as precision instruments, low noise electric motor, automobile, motorcycle, woodworking machinery, textile machinery transmission shaft, mining machinery, electromechanical equipment, plastic machinery, office equipment, medical equipment, fitness, national defense, aviation, aerospace and sports equipment and general machinery, etc.

Tolerance:

Standard deep groove ball bearings with average level, all consistent with GB307.1.

Radial clearance:

Standard deep groove ball bearings with C2, standard(CN), C3, C4 and C5 level internal clearance, and all consistent with GB4604. We also can produce the internal clearance as the customers requirement.  

Dynamic equivalent load

P = XFr + YFa [KN] 

Fr:  radial load  [KN]

Fa: thrust load    [KN]

Static equivalent load

P0 = Fr [KN]                  Fa/Fr≤0.8                           

P0 =0.6Fr + 0.5Fa [KN]        Fa/Fr＞0.8
