1. The deep groove ball bearing deep groove ball bearing layout is simple; the use is convenient; it is the largest production batch; the most widely used type of bearing. It first accepts radial load; it also accepts a certain axial load. When the bearing When the radial clearance is increased; the function of the angular touch bearing; a large axial load can be accepted. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Compared with other types of bearings of the same scale; such bearing conflict factor. Antagonism. This type of bearing can be used to accept pure axial load in the case of high speed and inferior ball bearing.
2, self-aligning ball bearing self-aligning ball bearing has two rows of just seeking; the inner ring has two raceways; the outer ring raceway is inner spherical shape; has the function of active self-aligning. It can actively compensate for the shaft and the shell Coaxiality error in the occurrence of body deformation; suitable for components in which the bearing seat hole cannot ensure strict coaxiality. The medium bearing mainly receives radial load; together with receiving radial load; a small amount of axial load is also acceptable; Generally not used to accept pure axial loads; such as accepting pure axial loads; as long as a row of rigid balls is stressed.
3, angular touch ball bearing angular contact ball bearing limit speed is higher; can accept the meridional load and axial load together; can also accept pure axial load; its axial load can be determined by the touch angle; and increase with the touch angle And increase.
Single-row angular touch ball bearings can only accept axial loads in one direction; when receiving the meridional load; returning causes additional axial force; it is necessary to apply the reverse load to the echo; thus; the bearings are generally used in pairs.
The double-row angular touch ball bearing can accept the warp direction with the warp load as the main direction; the axial two-way joint load and the torch load; it can restrain the axial displacement of the shaft or double shell; the touch angle is 30 degrees.
Paired device angular touch bearings can handle the warp direction with the warp load as the main direction; the axial joint load; can also accept the pure warp load; the tandem equipment can only accept the axial load in one direction; the other two equipments can accept Axial load in either direction. This type of bearing is generally selected by the manufacturer and then submitted to the user in pairs; there is preload and interference after the device; the ferrule and the rigid ball are in axial preload condition; thus improved The whole set of bearings as the support stiffness and rotation accuracy of a single support.
4. Cylindrical Roller Bearings The rollers of cylindrical roller bearings are generally guided by two ribs of a bearing ring; The roller and the guiding ring form a combination; it can be separated from the other bearing ring; it can be separated from the bearing. This kind of bearing device; the opening is more convenient; especially when it is needed. Outer ring and shaft. The shells are more powerful when they are engaged in cooperation.
Such bearings are generally only used to accept radial loads; as long as they are inside. Single row bearings with ribs on the outer ring can accept small constant axial loads or large intermittent axial loads.
Comparison of deep groove ball bearings with the same dimensions; such bearings have a large radial load. But for this type of bearing cooperation. The processing requirements of the associated parts such as the housing hole are high.
5. Spherical roller bearing Spherical roller bearing has two rows of rollers; it is mainly used to accept radial load; it can also accept axial load in either direction. The radial load of this kind of bearing can be high; uniquely applicable Working under heavy load or oscillating load; but can not accept pure axial load, excellent self-aligning function; can compensate for the same bearing error.
6. Tapered roller bearings Tapered roller bearings are primarily suitable for receiving radial and axial combined loads with radial loads; large cone tapered roller bearings can be used to accept axial loads. Axial combined load. This type of bearing is a separate bearing; its inner ring (including tapered roller and holding frame) and outer ring can be separated from the device. It can adjust the bearing's meridional clearance and axial travel during the installation and operation. Gap; can also pre-interference device.
7. Thrust ball bearing Thrust ball bearing is a kind of separate bearing; the shaft ring 'seat can be separated from the component of the self-supporting ball. The shaft ring is a ring that cooperates with the shaft; the seat ring is opposite to the bearing hole Cooperating ferrule; there is a gap between the shaft and the shaft.
Thrust ball bearings can only pull axial load; one-way thrust ball bearings can only accept axial load in one room; two-way thrust ball bearings can accept axial loads in two directions.
The thrust ball accepts the warp direction of the unconstrained shaft; the limit rotation speed is very low. The one-way thrust ball bearing can restrain the axial displacement of the shaft and the casing in one direction; the two-way bearing can restrain the axial displacement in two directions.
8. Thrust Roller Bearings Thrust spherical roller bearings are used for shafts that accept axial loads. Warp joint load; but warp load shall not exceed 55% of axial load. Compared with other thrust roller bearings; such bearing has lower collision factor; higher speed; and has self-aligning ability. 29000 type bearing roller It is an asymmetric spherical roller; it can reduce the relative sliding of the stick and the raceway during the operation; and the roller is long. The diameter is large; the number of rollers is large and the load capacity is large; the oil is generally selected to be smooth; the single low-speed condition can be used for smooth grease. In the description and selection; it should be preferred.
80000 type thrust cylindrical roller bearing. Model 90000 thrust tapered roller bearings and AXK thrust needle bearings; capable of accepting one-way axial loads; it is much larger than the axial load of thrust ball bearings; Occupied axial space is small. Thrust cylindrical roller bearings and thrust needle roller bearings are suitable for low speed applications; thrust tapered roller bearings have slightly higher rotational speed than thrust cylindrical roller bearings.
9. Needle bearing needle roller bearings are equipped with thin and long rollers (the length of the roller is 3~10 times the diameter; the diameter is generally not more than 5mm); therefore, the radial layout is compact; the inner diameter scale and load can be combined with other types. When the bearing is the same; the outer diameter is the most.

Outer roll appearance; the ability to adhere to the load and work function is the same as the ferrule bearing; the hardness of the shaft or shell hole raceway appearance. Machining accuracy and appearance and appearance quality should be similar to those of bearing rings. Such bearings can only accept radial loads.
10. Spherical ball bearings with seated spherical ball bearings consist of outer spherical ball bearings with sealed sides and cast (or stamped steel) bearing blocks. The internal layout of the outer spherical ball bearings is the same as that of deep groove ball bearings. However, the inner ring of such a bearing is wider than the outer ring. The outer ring has a spherical outer surface; it is actively aligned with the concave spherical surface of the bearing seat. Generally, there is a gap between the inner hole and the shaft of the bearing; the inner ring is fixed by the top wire; the pain sleeve or the tightening sleeve On the shaft; and with the shaft to transform together. The seat bearing layout is compact; convenient loading and unloading; sealed perfect; suitable for simple support; often used in mining. metallurgy. agriculture. Chemical industry. Textile. printing and dyeing. Shipping machinery, etc.
