Roller Bearings vs. Ball Bearings - What''s the Difference?

2 · For instance, a ball bearing running at moderate speed with a fairly loose fit might operate successfully with angular misalignment as high as 0.002 to 0.004 in./in. between the bearing and shaft. A cylindrical roller bearing, in comparison, might be in trouble if misalignment exceeded 0.001 in./in. Manufacturers will generally provide acceptable ranges of angular …

Setting Techniques for Tapered Roller Bearings | PTE

Unlike other types of anti-friction bearings, tapered roller bearings do not require tight control of shaft or housing fits to obtain setting. Because tapered roller bearings are mounted in pairs (Fig. 1), their setting is primarily dependent upon the axial loion of one bearing row relative to the opposite row.
