6004 zz bearing is a deep groove ball bearing

6004 zz bearing is a deep groove ball bearing, inner diameter 20mm, outer diameter 42mm, thick 12mm.  
Deep groove ball bearing 6004 zz can be used for gearboxes, instruments and meters, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, yo-yo and so on.

Deep groove ball bearing 6004 zz deep groove type continuous uninterrupted raceway.  There is a very good fit between the raceway and the ball, which can make the bearing bear two-way radial and axial loads. 6004 zz is very widely used, and the design is extremely simple and inseparable, suitable for stable operation in high-speed and ultra-high-speed environments, and basically does not need to do any maintenance from the point of view of maintenance.  And deep groove ball bearing is also the most widely used type of bearing.  
In structure, each ring of 6004 zz has a continuous groove raceway with a cross section of about one-third of the equatorial circumference of the ball. Compared with other types of bearings with the same size, this kind of bearing has small friction coefficient, high limit speed and high precision, so it is the preferred bearing type for user selection.  

Bearing 6004 zz is an important basic part of all kinds of mechanical equipment, its accuracy, performance, life and reliability of the host accuracy, performance, life and reliability play a decisive role.  In mechanical products, the 6004 zz bearings are high precision products, not only need comprehensive support the theory of mathematics, physics, and many other disciplines, but also need to material science, heat treatment technology, precision machining and measuring technology, numerical control technology and effective numerical method and the powerful computer technology in many disciplines, such as services, thus bearing is a product on behalf of the state science and technology strength.
