Generally, roller bearing are available to support heavier loads than similar size ball bearing and bearings having a full compliment of rolling elements can accommodate heavier loads than the corresponding caged bearing. The main function of lubricants is to prevent wear and heat loss in bearings. COLD DISMOUNTING Small bearing maybe removed from their settings by applying light hammer blows via a suitable drift to the ring face, or preferably by using a puller The claws of the puller should be placed around the side face of the ring to be removed or an adjacent component. Roller bearings are also available in various types. HOT MOUNTING It is generally not possible to mount larger bearing in the cold state, as the force required to mount a bearing increases very considerably with increasing bearing size . agy, Maintenance management - . DIRECTION OF LOAD Combined load :- A combined load comprises a redial and an axial load acting simultaneously For combined loads, single and double row angular contact ball bearing, and single row taper roller bearing are most commonly used, although deep groove ball bearing and spherical roller bearing are suitable. We know that it is easier to roll a wheel than slide it on the ground as the magnitude of rolling friction is lower than sliding friction. The gudgeon pin that connects the piston to the connecting rod in diesel engines is connected through a plain bearing.
