Ibid., the strengthening type and the ordinary type, in the shape, size, number, force conditions have changed?,Specific, such as the outer diameter and the size of the internal bore has changed, tapered roller bearings 30314, reinforced type is still called 30314; the force must be increased, in the axial or radial increase more?A friend who knows, tell, thank youMailbox: put awayThe seller said, "30314 bearings reinforced type", should be understood as an upgraded version of the meaning of it,Suppose, for example, that ha, which was originally made from carbon steel, was reinforced with alloy steel!
The same material, the same size, the installation method had no change, but the thickness change and keep the number of rollers and the inner sleeve. You can check the number of rollers. Reinforcement type should be radial bearing capacity increase, bearing capacity increase.
What do you mean by "strengthening" type? 30314 has a big cone angle, the model is 30314D, which can bear more axial load. The size is the same as the regular 30314.
The optimized structure design, the main installation dimensions of course change, just contact angle (the definition of inventory Reading University mechanical contact angle principle) the angle increased, along with some internal chamfer, raceway curvature improved. Bearing capacity, of course, is strongBut the speed has not changed much! What else is said about "China bearing"?.... Talking about it, the design and definition of the enhanced version were first made by TIMKEN and FAG. The Chinese copy it!FAG small cone followed by A.SKF suffix, with B, which means that both German or English abbreviations of words, to China, why is D, there are known to say a soundIn addition, the upstairs said that the way to guide, this with the specific environment for the internal and external circle, roller requirements, stress is different, but to take the inner ring guide, outer ring boot, or roller boot? Bearing in the three pieces of force conduction sequence is different, with strengthening type are two different things.The vast majority of bearings are internal (outer) tight ring, with roller transmission torque running.
