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?
Micro car owners differential speedMain reducing wheel hub of light truckMain reducing wheel hub for heavy truck
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:How to judge the positive and negative sides of the tapered roller bearings,
The bearings do not have to distinguish between the front and back, and there is no positive and negative said, only in accordance with your actual use to identify the installation direction.
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:Internal and external tolerances for tapered roller bearings?
This is not easy yet. Do you think it's possible to make a standard check instrument yourself?!
Q:Can tapered roller bearings be joined together with two single row tapered roller bearings instead of double row?The altar,
2, the clamping way is: double row bearing inner ring is double row, or outer ring double, determines when you install the inner ring or outer ring is clamped, clamped, if you want to replace with the two row, when combined with the clearance you need to consider the ring, you should adjust the clearance and is placed on the inner ring, or on the outside, too that depends on your way of clamping;
Q:Reasons for the damage of tapered roller bearings used on motors - -
But it is worth noting that you must control your parts tolerances, affect the tolerance of your variables clearance values are 11, 1 respectively -- bearing outer ring end face of large tolerances; 1 large end bearing inner ring outer ring end face 2 large tolerances; tolerances of bearings; 2 large end face of the inner face of tolerance between the two bearings, bearing; the small ring thickness tolerances; spacer ring tolerances; axial length tolerances; and two bearing diameter tolerances, and the corresponding axis tolerances (same axis but not at the same time processing is considered as two independent variables), consider the last four variables is because of you this application should be tightly matched with the inner ring, it will affect the clearance.

Q:How does the roller of tapered roller bearings fit in?
Tapered roller bearings are made up of outer rings, inner rings, rollers, and cages. The outer ring is a single body, and the inner ring, roller and cage are assembled together. They are called inner components. Tapered roller bearings belong to separable bearings, and when installed, the two components (inner and outer rings) can be fitted together.
