zz miniature bearing refers to the metric series, the outer diameter is less than 9mm; the inch series, all kinds of bearings with the outer diameter less than 9.525mm! The main materials of zz miniature bearing are carbon steel, bearing steel, stainless steel, plastics, ceramics, etc. The smallest inner diameter can be 0.6mm, and the general inner diameter is 1mm.
Characteristics of zz miniature bearing
In the ultra-small zz miniature bearing, the types of miniature deep groove ball bearings include metric 68 series, 69 series, 60 series, etc. There are 6 types of inch R series. On this basis, they can also be divided into ZZ steel plate protection. Dust cover bearing series, miniature bearing series with RS rubber seal ring, Teflon bearing seal ring series, flange flange series and so on.
Commonly used models of zz miniature bearing:

The main purpose of zz miniature bearing
zz miniature bearing is suitable for all kinds of industrial equipment, small rotary motors and other high-speed and low-noise fields, such as:
Office equipment, micro motors, instrumentation, laser engraving, small clocks, soft drives, pressure rotors, dental drills, hard disk motors, stepping motors, video recorder drums, toy models, computer cooling fans, currency counters, fax machines And so on related fields.
The solution when the temperature of zz miniature bearing is overheated:
1. Grease filling method. The so-called grease filling method is to fill an appropriate amount of grease on the working surface of zz miniature bearing regularly, which is the most commonly used grease lubrication method.
2. Oil cup method. The oil cup method is to set a screw cap oil cup or a pressure oil cup on the bearing seat, rotate the cap regularly or use a grease gun to inject grease. This is also a commonly used grease lubrication method.
3. Pressure grease supply method. Pressure grease supply method relies on grease pump for grease supply. At this time, grease with good fluidity should be selected.
4. Centralized grease supply method. The centralized grease supply method uses a grease pump to supply grease to each zz miniature bearing and other parts at the same time. Similarly, at this time, the grease should be a grease with good fluidity, oxidation resistance and corrosion resistance, which is also a pressure grease method.
