When the surfaces of bearing are separated by a fluid film, the bearing materials do not have any effect on its operation so long as the parts have sufficient strength to withstand the imposed loads and sufficient rigidity to maintain alignment. On account of streng…

A rivet is used to connect two or more plates. It is inserted through the hole in the plates and pressed on the other side. Unwin’s formula gives the diameter of the rivet hole for a given plate: d = 6*t 0.5 where t = Thickness of plate in mm and d = Diameter of the…

The screw thread is a continuous helical groove of specified cross-sections produced on the external or internal surface. A screw thread formed on a cylinder is known as a straight or parallel screw thread, while a screw thread formed on a cone or frustum is known as …

Ball bearing components are 1. inner ring, 2. outer ring, 3. balls and 4. cage. The standard essential components of a ball bearing are defined as follows: 1. Inner Ring: The Inner Ring is the smaller of the two bearing rings. The inner ring has a groove on its oute…

Rolling contact bearings are also known as anti-friction bearings due to their low friction characteristics between balls and inner and outer rings. Rolling contact bearings are used for radial, thrust, and a combination of these loads. Rolling contact bearings are of…
