6307 is a deep groove ball bearing.
and 7307 angular contact ball bearings.
Both have the same dimensions, both are:
The main differences between the two types of bearings are that the outer diameter d=80mm, the inner diameter d=35mm, and the width: b=21mm
The 6307 is mainly subjected to radial forces, but it can also withstand lighter axial forces.
The 7307 can not only withstand radial forces, but also according to different contact angles.
Divided into degrees) to withstand different degrees of axial force.
One thing to note is that the above are all new models, and in the old designation, 7307 means tapered roller bearing.

6307 is a spherical rolling bearing This bearing eliminates sliding friction resistance and cage, significantly reduces energy consumption and noise, improves the ultimate speed and load capacity of the bearing, and increases the service life by three times compared with the same type of bearing from SKF! 7307 is a vertebral thrust ball bearing Thrust ball bearing is a separable bearing, and the shaft ring's seat can be separated from the components of the cage rigid ball. The shaft ring is a ring that matches the shaft, and the seat ring is a ring that matches the bearing housing bore, and there is a gap between the shaft and the shaft.
Thrust ball bearings can only pull axial loads, and unidirectional thrust ball bearings can only bear one.

6307 is a deep groove ball bearing and 7307 is an angular contact ball bearing! The dimensions are: outer diameter * inner diameter * thickness = 80 * 35 * 21 (mm) The uses are:
6307 is mainly subjected to radial force and is basically not subject to axial force. The 7307 is capable of withstanding both axial and radial forces!

6313 belongs to deep groove ball bearings.
Deep groove ball bearings are originally listed as radial ball bearings, which are the most widely used rolling bearings.
The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retaining frames. There are two types of deep groove ball bearings: single row and double row, and the deep groove ball structure is also divided into two structures: sealed and open, open means that the bearing does not have a sealed structure, and the sealed deep groove ball is divided into dustproof seal and oil-proof seal. The dust seal cover is made of steel stamping, which simply prevents dust from entering the bearing raceway.
7313 is an angular contact ball bearing.
There are raceways on the inner and outer rings of angular contact ball bearings, and the inner and outer rings can be displaced relative along the axial direction of the bearing. These bearings are particularly suitable for combined loads, i.e. loads that act in both the radial and axial directions. The axial load bearing capacity of angular contact ball bearings varies with the contact angle.
of the enlargement. The contact angle is the angle between the contact point connection between the ball and the raceway in the radial plane and the perpendicular line of the bearing axis.

These two types of bearings are of different types, 6313 is a deep groove ball bearing, and 7313 is an angular contact bearing.

6317 bearings and 6317C3 can be universal, as follows: 1The letter M in the bearing 6317MC3 is the code of the cage god orange material for the light alloy solid cage, which is only available in the imported bearing, 2
There is no such code in China's national standard. Bearing 6317C3 is a cage stamped from steel or copper plate by default because the material of the cage is not marked. 3.
C3 refers to the third group of bearing clearance standards. Since the cage material performance of the two types of bearings is relatively similar, it can be used universally without <>

The first "6" indicates that the bearing type is a deep groove ball bearing; The second digit "2" and "3" are the bearing size series code, indicating the width series code 0 and the diameter series code 2 or 3; The third and fourth digits "07" are the bearing inner diameter code, indicating that the nominal inner diameter of the bearing is d=35mm.
There is only one difference between 6207 and 6307 is the different models.
According to the rolling bearing model code, professional and technical personnel can obtain some basic information of the rolling bearing, such as: load capacity, direction and nature; the maximum permissible speed reached; The rigidity of the bearing, the key factors such as the self-alignment performance and the installation error facilitate the subsequent selection of the bearing.

The seven series bearings are spherical roller bearings.
Spherical roller bearings have two rows of symmetrical spherical rollers, which are mainly subjected to radial loads, but can also bear axial loads in either direction, but not pure axial loads.
The raceway of the outer ring of this kind of bearing is spherical, so its self-alignment performance is good, can compensate for the coaxiality error, when the shaft is bent or installed differently than the bearing, the bearing can still be used normally, the self-alignment varies with the different bearing size series, and the general allowable self-alignment angle is 1 degree;
This type of bearing has a large load capacity, in addition to being able to bear radial load, the bearing can also bear the axial load of two-way action, has a good impact resistance, and generally speaking, the allowable working speed of the spherical roller bearing is low. It is suitable for working under heavy loads or vibration loads.
Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body, reduce the frictioncoefficient during its movement, and ensure its rotation accuracy.

Bearing 6308 and 6310, the difference between them is that there is a difference in the size of their bearing, and there are some small differences in the shape.

Hello dear, glad to ask your question: 7307rz is what bearing 7307 bearing system angular contact ball bearing, bearing model is 7307, bearing inner diameter is 35mm, bearing outer diameter 80mm, bearing thickness 21mm. Angular contact ball bearings can withstand both radial and axial loads.
RS – Synthetic rubber or polyurethane contact seal (contact type) on one side of the bearing. RZ - low-friction seal (non-contact) with steel lining plate synthetic rubber and negotiation on the surface of the bearing. If it is 2RS or 2RZ, of course, the front of the loft is brought on both sides.
720 bearing 5 and 6205 bearing are not the same type of bearing. >>>More
With the advent of the tide of internationalization, the domestic bearing code is gradually in line with the imported bearing code, and the latest published national standards show that the domestic code is basically consistent with the international ISO standard. Regarding the advantages and disadvantages of the two, please see the comparison between domestic bearings and imported bearings: >>>More
Definition and difference between the three:
1. FOB (Free on Board), also known as "free on board", is one of the terms commonly used in international markets. In the case of FOB transactions, the buyer is responsible for dispatching the ship to receive the goods, and the seller shall load the goods on the vessel designated by the buyer within the port of shipment and the specified time limit specified in the contract, and notify the buyer in a timely manner. When the goods are loaded onto the named vessel at the port of shipment, the risk passes from the seller to the buyer. >>>More
