The difference between roller bearings and ball bearings
When you say the same brand, the same lubrication and the same load, the life of cylindrical bearings is greater than that of the ball bearings.But you must be aware that these two types of bearings may be interchangeable, but they are often used in combination.If necessary, you can give me a message to help you type selectionThe same size cylindrical bearings and ball bearings: cylindrical bearings friction torque, speed almost equal. Cylindrical bearings limit speed is slightly smaller.About wear: because his bearing is greater than the ball, so the same load, certainly cylindrical bearing life expectancy.
In the same size:Speed: almost the sameRadial load: the cylinder is larger than the ball bearingIn accordance with general but under axial cylinder axial load direction or axial load (individual models can withstand axial load, bidirectional) is generally used in the free end of the shaft; ball bearings can withstand two-way load at the fixed end.
Life is generally related to speed, load, and environment.I hope you refer to the sample design.You can definitely tell: you should use ball bearings. Because your load is too smallI haven't seen the ball as long as you do. A small number of see, that is, buy Bearings demolition. You'd better get in touch with their office. Please look at my space. There is an import brand office in china.Not advertising. They don't do business. Your order will be sent to your nearest dealer.Finally, suggest that: you recommend using domestic P2 class steel ball, than the average quality of imported much better, the price may be high.Look, you know you are layman, hardness is the same, the quality of the steel ball to this grade, that is, the accuracy of the. P2 grade steel ball, as long as the ground will be scrapped, because this fall, the accuracy is not enough P2
