Types of Bearings | Uses & Working Mechanisms Explained

Aug 25, 2020· Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times. As needle bearings have a smaller diameter, more rollers can be fit in the same space which increases the surface area in contact with the races.
