The bearings are everywhere where there are transmissions. Here the below contents present you the types of bearings and their applications.
Deep groove ball bearing
Deep groove ball bearing is the most common and typical roller bearing, it has very wide applications. It can bear radial load and axial load, and is suitable for applications which require high speed rotation, low noise and low vibration.
Main applications:
Automotive: Rear-wheel, transmission, electrical equipment components
Electrical: General motors, household appliances
Other: instrumentation, internal combustion engines, construction machinery, rail vehicles, material processing machinery, agricultural machinery and industrial machineries, and so on.
Angular Contact Ball Bearing
There is contact angle between the cage ring and steel balls, the standard contact angle are mainly 15 °, 30 ° and 40 °. The larger contact angle the greater axial load capacity; the smaller contact angle the higher speed rotation capacity.
Main applications:
Single row angular contact ball bearing: machine tool spindle, high frequency motor, gas turbine, centrifuge and small vehicle front wheel, and so on.
Double row angular contact ball bearing: pump, blower, air compressor, various types of transmission, fuel injection pumps and printing machinery, and so on.
Four-point Contact Ball Bearing
It can bear radial load and axial load. A single bearing can replace the front combination or rear combination angular contact ball bearing.
Main applications: aircraft jet engine, gas turbine.
Self-aligning Ball Bearing
It can automatically adjust the shaft or housing deflection or misalignment caused by axis errors, because the outer ring raceway is spherical and has aligning capability.
Main applications: woodworking machinery and textile machinery shaft, and so on.
Cylindrical Roller Bearing
The cylindrical roller and the raceway is in line contact, it can bear large radial load. It is suitable for heavy load and shock load and also suitable for high-speed rotation N type and NU type axially move.
Main applications: Medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, handling and carrying machinery and other industrial machineries.
Entity -type Needle Roller Bearing
It has the basic structure of the inner ring bearing and is similar with the NU type cylindrical roller bearing. But because it applies needle rollers, the size can be reduced according to the requirement, and so it can bear very large radial load.
Main applications: car engines, transmissions, pumps, excavators track wheels, hoist, bridge cranes, compressors.
Tapered Roller Bearing
Tapered roller bearing can bear large axial load and also can bear large radial load. It is designed to make the inner raceway, outer raceway and the apex of the conical surface of the roller rolling face intersect at a point at the bearing center line.
Main applications:
Automotive: front wheel, rear wheel, transmission, differential pinion shaft.
Others: spindle, construction machinery, large-scale agricultural machinery, railway vehicles, gear reduction unit, rolling mill roll neck and deceleration devices.
Self-aligning Roller Bearing
There are spherical rollers between the spherical raceway outer ring and double raceway inner ring. They can be categorized into R, RH, RHA and SR 4 types according to the different internal structure.
Main applications: paper machinery , deceleration devices , rail vehicles axles, rolling mill gear box seat , rolling mill rolls Michiko , crusher, vibrating screen, printing machinery , woodworking machinery , all kinds of industrial gear , vertical seat belt aligning bearings.
Thrust Ball Bearing
It is composed of washer-shaped raceway ring and ball and cage components.
The raceway ring fitted with shaft is called shaft washer, and the raceway ring fitted with cage is called seat ring.
Main applications: automobile steering pin, spindle.
Cylindrical Roller Thrust Bearing
It is composed of washer-shaped raceway ring (shaft washer, seat washer) and cylindrical roller and cage components. Cylindrical roller is crowning processed, so the pressure distribution between the roller and the raceway surface is even. It can bear single direction axial load, and with large axial load capacity. Its axial rigidity is also strong.
Main applications: oil rigs, iron steel, machinery manufacturing.
Needle Roller Thrust Bearing
It’s a type of thrust bearing, and the roller is needle type, so it’s called needle roller thrust bearing.
Main applications: transmission devices of cars, plowing machines and machine tools.
Tapered Roller Thrust Bearing
It’s kind of thrust bearing and the roller is tapered, so it’s called tapered roller thrust bearing.
Main applications: unidirectional: crane hook, swivel oil rig.
Bidirectional: roll neck of rolling mill.
Self-aligning Thrust Roller Bearing
The roller of this kind of thrust bearing is spherical roller, so it’s called self-aligning thrust roller bearing.
Main applications: hydroelectric power, vertical motors, marine propeller shafts, rolling mill rolling screw with a reducer, tower cranes, coal grinding machines, extruders, molding machines.
So above are the descriptions of the main types of bearings and applications. At FITRUN
