Spherical Plain bearing | Image Resource: indiamart.com When it comes to the proper maintenance of any machine, bearings play important role in the smooth functioning of it. Let it be any machine, it cannot function properly without the assistance of bearings. It ensures smooth functioning by reducing friction between two moving elements. A bearing acts as a lubricant and reduces friction and heat during movement of machinery parts.
There are a wide range of bearing available in the market which are used in different application and machinery. They are generally categorized based on the rolling element built in it. Some of the bearing are ball bearings. Spherical bearing, cylindrical bearing and so on. Here let us see the features of Spherical Plain bearing Spherical plain bearing A spherical plain bearing allows angular rotation in two directions, it is generally based on the central point within a specified limit. Basically, such bearings work well with rotating shaft in a rotational manner at an angle. Most significant future of the bearing is its self-aligning capability and for this reason spherical plain bearing is used in mill shafts which have long shaft. A spherical bearing consists two rings like inner and outer ring. Furthermore, it has a locking feature to make the rings rotate axial direction only. The rings in spherical bearings are spherically shaped and slide against each other. This bearing acts as a best lubricator and hence is a maintenance-free bearing. The polytetrafluoroethylene or PTFE rolling element helps reduce friction. You can find different types of rolling element in a bearing such as steel, brass, plastic PTFE and so on. The Spherical plain bearing is used in different applications where rotational motion is needed to be handled. One among the areas of application of these bearings are in a vehicle it is used as a drive axle bearing to control arm. The suspension of the bearing allows the axle to move and the wheel to turn. The axle bearings allow the axle, yet they are not used in vehicles in practice. Practically, spherical bearings are widely used small components such as sewing machines driver shafts, robotic applications and so on. To provide additional support to a anti-frictional bearing a housing known as a pillow block is added. This is known as pillow block bearing, which refers to any mounted bearing. A pillow block consists of any type of bearing such as ball, cylindrical, spherical or tapered roller. It provides more safety and easy to mount feature. On the other hand, an angular contact bearing is used to support combined loads and they are available single, double and multiple rowed bearing.
