Plain bearing and their working 

A plain bearing, also known as a sliding contact bearing or slide bearing, is the most basic type of bearing. It merely has a bearing surface and no rolling components; thus it is also referred to as a solid bearing, journal bearing, the journal—the portion of the shaft that contacts the bearing—slips across the bearing surface.
A shaft turning in a hole is the most straightforward illustration of a plain bearing. A pair of flat, motion-permitting surfaces, such as a drawer and the slides it rests on or the ways on a lathe's bed, can serve as a simple linear bearing. Awwa technologies manufactuered best plain bearings.

Usage of plain bearings  

When should you use plastic plain bearings versus metal ones? Giving concise responses to these queries is difficult. The market is vast and intricate, and new items are always being introduced, expanding the scope of use and providing fresh benefits. However, I'll give you a general overview, highlight the benefits and drawbacks, and provide a few application examples here. 

Working of plain bearings 

Plain bearings are formed of two parts. There is the stationary component, known as the support, which carries the loads, and there is the area that wears out, or the component that comes into touch with the moving element: the bush. To reduce the losses caused by bearing friction, low friction material pairs are typically employed, or lubricants such solid graphite or Teflon, liquid oil, or gaseous pressured air are injected between the parts.

  • Sleeve bearings 
    The most prevalent type of planar bearing, sleeves sustain rotating, oscillating, or linear shafts. 
    They operate through a sliding motion. 

    Flange bearings 

    A shaft that is perpendicular to a bearing's mounting surface is supported by flange bearings. A sleeve bearing can be held in place using a locating mechanism that is built into the bearing's flange (or rim). Flange bearings lessen surface friction during both rotary and linear motion. 

    Mounted bearings 

    Mounted bearings need to be precisely engineered to specs in order to ensure the best fit. Too-loosely mounted bearings might creep or slip on a shaft. Or free mobility could be restricted if the press fit is too tight. Plastic plane mounted bearings are available in pillow-block or flange housings, with shapes ranging from 2-4 holes, to allay this worry.   

    Thrust bearings 

    Simple washers are incorporated into the design of these plane bearings to guard against metal-to-metal contact during thrust load applications. Thrust bearings made of plastic are lightweight, simple to install, and self-lubricating to lower maintenance expenses. 

    Spherical bearings 

    Spherical bearings can adjust for any shaft misalignment by rotating in two directions. Typically, they are required to support a spinning shaft that requires both rotational and angular movement.
