A bearing is a mechanical device which provides relative motion between two or more parts. Bearings are widely used in various industrial as well as in our day-to-day applications. Bearings permit four common types of motions like linear motion (for eg. drawer), spherical motion (for e.g. ball and socket joint), axial motion (for eg. shaft rotation) and hinge motion (for eg. door, elbow, knee). There are different types of bearings used in mechanical devices. Using a suitable bearing in many applications help in improving accuracy, efficiency, reliability, operation speed, purchasing costs of operating machinery.
Types of Bearings
There are many types of bearings each used for different aplications and different purposes. Bearings can be used either singularly or in combinations. Bearings are classified broadly according to their motions, operating principle, load capacity and speed and size they can handle. Accordingly, we find bearings of different shapes, speed, lubrication, materials and so on. The most popular bearing types are given below.
