Journal grinders are basically used for machining and giving a surface finish to crankshaft, gun barrels, and flanges .Pin grinding and journal grinding is carried out on the automated Landis Journal Grinder. The bearings present in these grinders are deep groove ball bearings .These balls bearings restrict the relative motion between the fixed element and the rotating element that is frame in headstock and spindle. So it reduces rotational friction and supports radial and axial load. Due to heavy loads and large grinding force, great amount of radial and axial force exerted on bearing. Because of this, wear and tear of deep groove ball bearing occurs, Thus reducing the life of bearing. So, there is a need to find an alternative solution to this problem. Therefore we studied and analyzed different types of bearings and came to the result that angular contact bearings can be used in the Landis Journal Grinder, because these have the capability to withstand heavy axial forces and radial loads, this is due to angular type of contact. More the angle of contact, greater the axial thrust or load, the bearing can withstand.
