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:Tapered roller bearings. Are the rollers tapered?
The frustum of the cone can be seen as a right angled trapezoid revolving around the right angle, and the top is a circle. Can also be seen on top of the tip is tapered off, the tapered roller head is not a round face
Q:Dimension parameter of thrust tapered roller bearing.
National standard GB 4663-1984, roller bearings, thrust cylindrical roller bearings, size, please check the mechanical design manual (Fifth Edition), second volumes --- commonly used rolling bearings, dimensions and performance parameters / thrust roller bearings.
Q:What are the E and Y values of the 30209 bearings of tapered roller bearings?
The shoulder of the positioning shaft is positioned; the transition shaft shoulder is provided for the disassembly of the parts on the shaft or the prevention of the stress concentration. But the axial shoulder will inevitably increase the diameter of the shaft, and the shoulder of the axle will change due to the stress concentration.
Q:Tapered roller bearing suffix code YA2 stands for what does that mean?
SatisfyHappiness is merely material meet? Of course not, happiness is not simple and get food and drink happy nor personal desires superficial meet. Wealth has sometimes not happy, luxury, and happiness cannot lead a gay life equate. Therefore, the material does not meet the real happiness.It is the balance of happiness tends to meet the spirit of Confucius, "there are friends from afar" or "awfully";
Q:What does "tapered roller bearing" suffix "A" mean?
Tapered roller bearing suffix AA - angular contact ball bearings with a contact angle of 30 degreesA5 - angular contact ball bearings with a contact angle of 25 degrees
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:Can tapered roller bearings be joined together with two single row tapered roller bearings instead of double row?The altar,
Not so simple, please consider the following: 1, clearance of double row bearings generally have clearance design, and no single, you need to set in the middle of every lap, with good clearance, clearance or big or small, or no clearance, you miserable;
Q:Is the tapered roller bearing so correct?
Tapered roller bearings are designed for the inner ring, outer ring raceway and roller cone vertex on the central axis of the bearing, radial load acting on the bearing, axial force is generated. Therefore, it is necessary to use the 2 bearings for use, or as double pairs of bearings, double row bearings. Combination and double row tapered roller bearings, when radial loads act on tapered roller bearings
Q:Tapered roller bearings, 70 in diameter, please tell me the model number
What about outside diameter (D) and width (B)? You didn't say?.Following are all series of codes and sizes for tapered roller bearings (single column and double row).

Q:How does the roller of tapered roller bearings fit in?
Tapered roller bearings itself can be broken down, and new (or old) bearings are cleaned and decomposed. So do not worry, carefully installed in accordance with the original installation order on the line, and if it does not meet the installation order, the installation of this bearing is not go on.
