Harbin Bearing Group Corporation is China's bearing industry, one of the three major production bases, now has total assets of 3.67 billion yuan, the main production equipment about more than 4600, annual production capacity of more than 80 million sets. The bearings can produce nine types, various levels of precision more than 6000 kinds of specifications and varieties. Mainly used in automobile, agricultural machinery, locomotive vehicle, motor, electrical appliance, engineering machinery, machine tools, textile and light industry, metallurgy, mining machinery, petrochemical, aerospace, national defense and so on industries and enterprises supporting services. The products are sold to domestic provinces, municipalities and autonomous regions, but also exported to Europe, Southeast Asia and other countries and regions in part.

HRB bearing classification

HRB HRB thrust ball bearing, deep groove ball bearings, spherical roller bearing HRB.

HRB spherical roller bearing

Spherical roller bearings can bear large radial load, also can withstand the axial load. This kind of bearing outer ring raceway is spherical shape, so it is self-aligning performance, when the axial force bending or tilt the inner center line and center of the outer ring line relative slope up to a maximum of 1 to 2.5 degrees bearing can still work. Spherical roller bearing inner hole of cylindrical and conical two. Conical taper of hole of 1:1 2 or 1:30. In order to strengthen the lubrication performance, machining the annular oil groove and three uniform oil hole in the outer ring of the bearing. Spherical roller bearings used to carry heavy load and impact load, widely used in the industries of metallurgy, rolling mill, mining, oil, paper, cement, sugar.

HRB thrust ball bearings

Thrust ball bearing:

Thrust ball bearings by seat, shaft ring and ball retainer assembly is composed of three parts.

The shaft with the said shaft ring, matched with a shell called seat.

Thrust ball bearing type:

Acceptance of one-way thrust ball bearing and thrust ball bearing.

Thrust ball bearings, can withstand axial load.

Two-way thrust ball bearings can withstand two-way axial load. Bidirectional thrust ball bearing ring and the shaft with them. Bearing installation of seat spherical surface, with self-aligning performance, can reduce the influence of the installation error.

Thrust ball bearings can bear radial load, limit rotational speed is low. Thrust ball bearing is only applicable to withstand side axial load, speed lower parts, such as the crane hook, immediately pump, immediately centrifuge, Jack, speed reducer. Bearing ring, ring and rolling bodies are separated, they can respectively put down.

HRB deep groove ball bearing

Deep groove ball bearings imported bearings are used to withstand pure radial load, also can bear radial load and axial load. When the only subject to pure radial load, the contact angle is zero. When the deep groove ball bearings with a larger radial clearance, with angular contact bearing performance, can bear large axial load. Deep groove ball bearing friction coefficient is small, the limit speed is very high, especially under the axial load a lot of high speed operation, deep groove ball bearing thrust ball bearings are more advantages than that. Deep groove ball bearings are the most representative and widely used. Suitable for high speed and high speed operation, and very durable, without frequent maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low manufacturing cost, easy to manufacture high precision. Size range and form variety, application in precision instruments, low noise motors, automobiles, motorcycles and general machinery, and other industries is a broad class of bearing used in machinery industry. Mainly bear radial load, also can withstand a certain amount of axial load of deep groove ball bearings can be used for gear box, instrument and meter, motor, household appliances, internal combustion engine, transport vehicles, agricultural machinery, construction machinery, engineering machinery and other

Select bigger radial clearance axial bearing capacity increases, under pure radial force when the contact angle is zero. Under the action of axial force, contact angle is greater than zero. General use of the stamping wave shape keep frame, car solid cage, sometimes using nylon frame. Deep groove ball bearing is installed on the shaft and the bearing axial clearance range, limit the axial displacement of the shaft or housing two directions. Therefore, it can be used in axial orientation. In addition, this kind of bearing has certain self-aligning capability, when the inclined 2 '- 10' relative to the shell hole can still work normally, but it had a certain effect on the bearing life. Deep groove ball bearing retainer for stamping steel ribbon cage, large bearing of the metal entity keep a car.
