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 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?
Mr. Liu five love reading, "gladly forget to eat" every knowing; ong drinking is not wine, but for mountains and rivers ". So Mr. Qian Zhongshu proposed" all happiness enjoy all belong to the spirit of "the world as truth, but think, feel spiritual satisfaction is also flawed, sometimes even the feeble.
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: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 are the conditions for the normal and reverse loading of tapered roller bearings?
When the transmission parts between the two bearings, the formal wear of the pressure center to reduce the distance, and help to improve the rigidity of the shaft, the reverse is the opposite. Therefore, two contact ball bearing or tapered roller bearing suits and reverse installation should be based on the transmission parts (gear, worm) considering the structure and the axis. And choose to use.
Q:Small problems of roller bearings of tapered roller bearings
Roller tapered roller bearing is a conical body, sometimes drawing simplified painted section cylinder, not misleading (a type of list), is also permitted.-- -- -- -- --
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:Is the tapered roller bearing so correct?
Tapered roller bearingTapered 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: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:Method or tool for measuring clearance of tapered roller bearings.
This should be accomplished by tightening the clearance of the gear box end cover.
