BEARINGS
INTRODUCTIONBEARINGS:-Bearings are machine elements which are used to support a rotating member called as shaft. They transmit the load from a rotating member to a stationary member known as frame or housing

Sliding Contact Bearing:- The sliding take place along the surface of contact b/w the moving element and fixed element.It is also known as plain bearings.In which the sliding action is guided in straight line & carrying radial load .
Fixed element
Moving element
TYPES OF SLIDING CONTACT BEARING:-
1)Full journal bearing:-2) Partial journal
bearing:-3) Fitted journal
bearing:-
Advantages:-1. Higher load carrying capacity. 2. Easy replacement. 3. Infinite life.
Disadvantages:- 1. In some cases you need to have a dedicated lubricating system.2. More expensive.
Rolling Contact Bearing:-
Load is transferred through rolling elements such as balls, straight and tapered cylinders and spherical rollers.Due to low rolling friction these bearings are aptly called “antifriction” bearing.
Types of Rolling Contact bearing:-1)Ball bearing 2)Rolled bearing 3)Thrust ball bearing
Advantages:- The rolling bearings have a lower frictional
resistance than plain bearings. The Lubrication of rolling bearings is easier
because they can be "grease packed‘. A greater choice of roller bearing designs are
available than for plain bearings.Disadvantages:- It takes up more space than plain bearings. The rolling bearings are not as rigid as plain
bearings. More nosier in operation than plain bearings. High cost.
