1, deep groove ball bearings
Deep groove ball bearing structure is simple, easy to use, is the largest production volume, the most widely used type of bearings. It is mainly a radial load to bear, can withstand a certain amount of axial load. When the bearing radial clearance increase with angular contact bearings subjected to high axial load.
Compared with the same size as other types of bearings, such bearings friction factor is small, high speed limit. Speed ??is high, should not adopt the reasoning of ball bearings can be kind of bearings under pure axial load.
2-aligning ball bearings
There just to get two-aligning ball bearings, the inner ring has two raceways, the outer ring raceway within a spherical shape, with self-aligning performance. Can automatically compensate for the deformation axis Rao song and shell concentricity error, apply to the bearing seat hole can not guarantee strict concentricity parts. The bearings mainly take radial load and radial load can withstand a small amount of axial load, are not typically used under pure axial load, such as under pure axial load, and only a hard-sphere force.
3, angular contact ball bearings
Angular contact ball bearings higher speed limit, you can also withstand their axial load capacity is determined by the contact angle can also be subject to pure axial load and axial load, with the contact angle increases.
Single row angular contact ball bearings can only support axial load in one direction, the additional axial force to bear by the load, back, reverse load must be applied to the response, so this type of bearing is generally used in pairs.
Teach large by the load mainly by the double row angular contact ball bearings can withstand axial joint bi-directional load and force Ju load, it can limit axis or dual-shell two-way axial displacement, the contact angle of 30 degrees.
Installed in pairs of angular contact bearings, pumping hands by the load mainly by axial load, and can withstand pure by the load, tandem configuration can only afford a single direction axial load, the other two configurations can afford The axial load in either direction. This type of bearing is generally paired by matching combination of the manufacturers submit a user after installation preload earnings, rings, and just ball in the axial pre-load state, thereby enhancing the entire group bearing a single bearing supporting stiffness and rotation accuracy.
4, cylindrical roller bearings
Cylindrical roller bearings, roller is usually guided by two ribs of a bearing ring, cage roller and guide ring is composed of a combination with separation and the other bearing ring, and belongs to the separable bearing. Such bearing installation and removal is more convenient, especially when the request. Outer ring and the shaft. Shell are too tight fit also show advantages.
Such bearings are generally used only for radial loads, only the outer ring are single row bearings with ribs can withstand smaller steady axial load or intermittent axial load.
Compared with the same dimensions of deep groove ball bearings, such bearings with a larger radial load capacity. Higher but for the kind of bearings with the axis of the shell holes, such as parts of the process.
5, spherical roller bearings
Aligning roller bearings, two roller is mainly used to bear radial load, but also able to withstand the axial load in either direction. This kind of bearing capacity of radial load, especially for overloaded or vibration load, but can not afford the pure axial load; good performance of aligning compensation with the bearing error.
6, the tapered roller bearing
The tapered roller bearings to withstand the radial load mainly radial and axial load, the large cone angle tapered roller bearings can be used to withstand the axial load mainly radial, axial joint load. Such bearings are separable type bearings, the inner ring (including tapered roller and cage) and the outer ring can be installed separately. Can adjust the bearings in the process of installation and use by the clearance and axial clearance can be pre interference installation.
7, thrust ball bearings
Thrust ball bearing is a separation of bearings, shaft ring 'seat and cage `hard-sphere component separation. Axial ring matching ferrule axis, sitting circle to match the ring and the bearing hole and shaft gap.
Axial load for thrust ball bearings can only be pumping hands, one-way thrust ball bearings can only support axial load of a room, two-way thrust ball bearings can withstand axial load in both directions.
Thrust ball bear can not limit the axis by the shift to as low speed limit. One-way thrust ball bearings can limit the shaft and the axial displacement of the direction of the shell, two-way bearings can be restricted in both directions of the axial displacement.
8, thrust roller bearings
Aligning thrust roller bearings to withstand the axial load the main shaft to the combined load to the load, shall not exceed 55% of the axial load. Compared with the other thrust roller bearings, such bearings friction factor is low, high speed, and aligning capacity. 29000 type bearing roller asymmetric spherical roller, can reduce the relative sliding of the stick and the raceway at work, and the roller diameter, the number of roller load capacity, usually with oil lubrication, individual low speed can be used for grease lubrication. In the design selection, should be preferred.
.90000 Type of thrust tapered roller bearings 80000-type cylindrical roller thrust bearings and AXK type thrust needle roller bearings that can withstand a one-way axial load, which is much greater than the thrust ball bearing axial load capacity and rigidity. occupy axial space. Thrust cylindrical roller bearings and thrust needle roller bearings for low speed applications, thrust tapered roller bearings speed slightly higher than the thrust cylindrical roller bearings.
9, needle roller bearings
Equipped with a thin and long roller needle bearing (the length of the roller diameter of 3 to 10 times the diameter of not more than 5 mm) and therefore radial structure is compact, its inner diameter and load capacity and other types of bearings at the same time, minimum outside diameter of the supporting structure is especially suitable for radial mounting dimensions restricted. Depending on the use of different occasions, the choice of the inner ring of the bearing or needle and cage assemblies directly match with bearing journal surface and the surface of the shell hole as the bearings inside the outer rolling surface in order to maintain the load capacity and running performance with a ring bearing the same axis or shell hole roll Road surface hardness. machining accuracy and surface and surface quality should be similar to the raceway of the bearing rings. Such bearings can only bear radial load.
The 10 LNSERTED ball bearings
The LNSERTED ball bearings from both sides with a sealed spherical ball bearings and casting (or steel stamping) bearing composition. The internal structure of the deep groove ball bearings, spherical ball bearings, but such a bearing inner ring width in the outer ring the outer surface of the outer ring has a cross-sectional spherical self-aligning bearing concave spherical match. Usually such a bearing bore and the shaft there is a gap between the top wire, the eccentric sleeve or adapter sleeve bearing inner ring is fixed on the shaft, together with the shaft rotation. Bearings with Housings - compact, convenient loading and unloading, perfect seal, suitable for simple support, commonly used in mining, metallurgy, agriculture, chemical, textile printing and dyeing. Transport machinery.
