Bearing introduction
Characteristics
It consists of an outer ring, an inner ring, a set of steel balls and a set of cages.
It mainly bears pure radial loads, but also can bear joint loads. When it is subjected to pure radial load, its contact Angle is zero. When it has a larger radial game, that is, it has angular contact bearing performance, which can withstand a larger axial load.
Deep groove ball bearing has small friction coefficient and high limit speed, so it has more advantages than thrust bearing when axial load is rotating at high speed.
Groove ball bearings are simple in structure and easy to achieve high precision compared with others.
Iron sealed bearings
Rubber sealed bearings
Open sealed bearings
Bearing is sealed by steel on both sides.
Advantages: High speed,has a good dust effect. Disadvantages: Can not prevent the intrusion of liquid debris.
Advantages: High speed,has a good dust effect. Disadvantages: Can not prevent the intrusion of liquid debris.
Bearing is sealed by black, blue or other colful rubber on both sides.
Advantages:To prevent any foreign intrusion,super dust effect. Disadvantages: The price is relatively high,the general speed.

Bearing comes without seal on any side.
Advantages:High speed,idling effect . Disadvantages: Dust effect is poor,easy into the dust,impurities and so on.

FAQ
1Q1:What is the type of bearing with inner diameter 10 and outer diameter 30 and thickness 9?
A:According to GB/T276-1994 national standard, the bearing type belongs to 6200.
Belongs to deep groove ball bearings. Used to bear radial load, can also be used to bear a certain axial load.
6: Deep groove ball. 2:2 series bearings.
6200 bearing: diameter of inner diameter 10㎜, diameter of outer diameter 30㎜, width 9㎜, weight 0.030 kg.
2Q2:How to distinguish the identification of the inner and outer ring of bearings?
A:Generally speaking, the inner and outer rings of bearings are not marked. In the bearing model, the unified model of different bearings is formed. And this model represents its outer ring diameter, inner ring diameter, bearing thickness and so on. For example, 6200 Z1, the front indicates the bearing type, and the back indicates the bearing (noise) level. Of course, there are also many non-standard models, which can be bearing specific parameters according to the comparison table. As bearings are high precision parts, they are generally not engraved directly on the bearing. Some will be laser stamped on the end face of the bearing outer ring, and some will be engraved on the dust cover with a good model and the English or Pinyin abbreviation code of the manufacturer's name.
3Q3:What is the meaning of 6208-ZZ bearing model?
A:Model number: 6208-ZZ, meaning: deep groove ball bearing, light and narrow series, inner diameter 40, outer diameter 80, thickness 18, ZZ means double-sided dust-proof seal cover
