Product Description:

Specificatioin of Taperder Roller Bearings:

The tapered roller bearing is to bear the combination of radial and axial load but mainly afford radial load. The loading capibility is determined by the raceway angle of outer  ring, the larger angle afford larger load. This kind of bearings can be  seperated and it can be divided into single-row and double-row tapered roller  bearings by the number of columns. The clearance for single-row tapered roller  bearing should be adjusted by the customers when installation. For the  double-row tapered roller bearings,the clearance has already set by the  manufacture before ex-factory. Tapered roller bearing has taper shaped inner  ring and outer ring raceway,and the roller elements arrange between them. All  projection lines from the surface of rollers meet at the same point on bearing  axis. This design makes tapered roller bearings particular suitable for combined  (axial and radial) loads.The axial loading capacity is determined by the  contacting angle α, the bigger angle for α, the larger axial loading capacity  is. Tapered roller bearing is usually a seperated bearing, that is,the inner  ring assembly including roller and cages, is seperated installed with the cup.

Taper roller bearings are mainly used for radial and axial joint load with radial load as main subject. Axial load capacity relies on raceway angle of outer ring: the bigger the angle is, the bigger the bearing capacity is. Outer ring can be separated and can be easily assembled. During installing and using process, axial clearance and radial clearance and radial clearance can be adjusted and pre-interference installation can be allowed. 


Product application:

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.

Q:What are the general uses of tapered roller bearings?
Widely used in machinery and equipment, water conservancy and Hydropower Engineering, railway, automobile, steel, textile, packaging, medicine, metallurgy, mining, petroleum, electric power, papermaking, computer, motor, sports equipment, office equipment, instrumentation, auto motor, precision instruments and other fields
Q:What is the 30207 judgment coefficient e of tapered roller bearings?
Your adoption is the driving force of my progress~~O (a O, a _) remember praise and adoption, help each other.
Q:What is the size of tapered roller bearings 352214?
Bearing type: tapered roller bearingNew model: 352214Old model: 97514EInternal diameter (mm):70Outside diameter (mm):125Width (mm):75
Q:What items should be inspected for tapered bearings?
2, tapered roller bearings are not allowed to have an electric drill pattern, vibration patterns, yin and Yang face and polished traces, did not promise to emerge supporting construction and obvious measurement traces, did not agree to knock bumps and obvious color difference.3, the name of the whole machine did not promise to have oxide skin.
Q:The installation of tapered roller bearings
1, for example, a shaft needs to be fitted with two such bearings at both ends. Can it be installed in the same direction?The force of the shaft is concerned. If the shaft is indeed subjected to one-way axial force, of course, it can be installed in the same direction. If it is subjected to biaxial axial force, it will not work
Q:Small problems of roller bearings of tapered roller bearings
Cylindrical rollers are used only when the raceway is a cylinder.Mechanical drawing clearly stipulates the simplified drawing method of tapered roller bearings. Rollers are drawn into cylinders.
Q:Tapered roller bearing: Bearing expert why burned or locked
2, the bearing seat hole size deviation is too small or the size of the shaft deviation is too large, extrusion bearing ring deformation, make the clearance smaller. To burn locking phenomenon.3, bearing outer diameter and bearing seat hole, or between the bearing bore and the surface of the shaft between the foreign body, such as iron filings, burr, sand, cotton and so on. Will also squeeze bearing deformation, so that smaller clearance. To burn locking phenomenon.Bearing burnt lock. The cause of the accident can be analyzed according to the burning degree of the inner shell, the outer shell and the roller1. The inner shell burns most severely, the roller slightly lighter, and the outer shell almost does not change. After excluding the reasons for the nonstandard size of the inner bearing housing, the following judgment can be made.
Q:Reasons for the damage of tapered roller bearings used on motors - -
To LZ: 1 it is recommended that the radial force and the rated load of the bearing be compared to determine whether the radial force is too large (if there is axial force, it needs to be synthesized as equivalent load, and then compare.) In 2 section, you basically is the middle of the two row tapered bearing ring and then as a double row tapered to use (not in general, so natural clearance installed back to back) without gasket or nut to adjust, this is a very good idea.

Q:Tapered roller bearings 32010x, two matching, how to install?
The design of this kind of bearings makes the inner ring raceway, outer raceway and the top of each cone face intersect the point of the central line of the roller. In addition to metric series products, there are a variety of English series products.
