Plainbearing examples

With the purpose of minimizing the losses generated by the bearing friction, material pairs with low friction coefficient is generally used, or a lubricant is added between the parts: solid – graphite or Teflon -, liquid – oil – or gaseous – pressurized air.

Plain bearings are mechanical components charged with bearing a load and allowing a sliding or rotational motion between two parts of a machine. Their main purpose is preventing wear of the points of support of the machine, which would take place if the shafts were to roll directly on the structure.

WoW !! Its Was So beautiful To reading !! I Have learn so many things from this site!! As a mechanical Engineer .. i just give you Thank you !!

What is aplainbearing

In them, the journal of the shaft and the rolling surface of the support are separated by rolling elements, so that when the journal or the bearing rotates, a rolling motion is generated instead of a sliding one.

In many occasions, rolling bearings perform the same functions than plain bearings, but the selection of one or the other in a project depends on the end use they may be given.

In one of its success stories, CLR’s team decided to use plain bearings, since they exceeded the mechanical requirements for the equipment and allowed for a cheaper shaft rotation, being the best solution, and the most beneficial for its customer.

The three types of plain bearingsand their functions

They are composed of two rolling rings separated from each other by other equally rolling elements that are located between them, whose shape varies depending on their use.

This is the reason why, when choosing your component supplier, you should keep a number of factors in mind, such as the professionalism and quality of its team, without forgetting about its reliability and zeal, two fundamental aspects in order to lead your projects to success.

Are you involved in a project but knowing which bearings you need is giving you headaches? Don’t worry! In this post we will tell you about its uses and types. Let’s get to it!

They are also known as bushes, solid bearings and friction bearings, generally have a cylindrical shape and contain no moving parts.

Plain bearings are composed of two parts. On one hand, there is the fixed part, which bears the loads, known as the support, and on the other, the area that gets worn; in other words, the one that is in contact with the moving element: the bush.
