What are the minimum carrying capacity and ultimate speed of ball bearings and roller bearings of the same size?
Ball bearings point contact, roller bearings line contact, so the same outer diameter of the ball bearing capacity is correspondingly smaller
Compared with roller bearings, ball bearings have higher ultimate speed, but smaller bearing capacity;Compared with ball bearings, roller bearings have lower speed limit and higher bearing capacity.
So, the same size, the ball, like the light cavalry, point contact, fast, small force, roller, like armored soldiers, line contact, slow, but powerful.Again, the ability to resist impact, resistance to fatigue is also the ability of the roller. Some roller bearings, such as tapered bearings, some cylindrical bearings, and the ability to withstand axial forces, of course, deep groove ball and angular contact ball can also be, but only a lot of small, here no longer speak. Finally, the price, in general, is cheaper than roller bearings.
