Generally, all types of machinery are provided with supports for rotating shafts; the supporting device is known as a bearing. In other words, a bearing is a machine element that constrains relative motions and is used to reduce friction between moving parts.
Bearing employs to support, guide, and restrain moving the element. This is a stationary member, and it carries the load.
The common applications of bearings are:
Shafting in workshops,
Spindles of a machine tool such as a lathe, drilling, milling machine, etc.
The crankshaft of engines, axles of automobiles, etc.
Types of Bearings
Following are the different types of bearings:
1) Rolling Element Bearing
2) Plain Bearing
3) Fluid Bearing
4) Magnetic Bearing
5) Jewel Bearing
6) Flexure Bearing

Hello. I work in a Bearing plant. I would like to add to the types of roller Bearings. First Cylindrical can have a lot of sub types based on if the Outside ring or Inside Ring is fixed and it can be a construction of 1 row, 2 row or 4 row bearing . A combination between the Spherical and Taper roller bearings you can have a Thrust bearing. Taper roller bearings come as well in different types depending on number of rows and type of cage. You can have a cage that is pressed to lock the rollers or a cage that is welded. You can have a removable rib on the inside ring. A different cage used for Taper and cylindrical roller bearings can be a construction of shafts that go true the center of the roller and are welded to a top and lower ring building the cage. I seen no mention of Cross Roller Bearings. There are a lot of other subtypes for each but that would be the main bearings in the roller Bearings sector that you did not mention.

@JohnTheSten 2 года назад

Could you describe difference between bearings a bushings, please? I personaly would call some types in video as bushings but i guess i am wrong.

@Alexandru_Iacobescu 2 года назад

@@JohnTheSten I’m not a bushings expert. I know more about roller bearings specifically. From what I know a bushing main purpose is to reduce NVH by replacing a fix connection with one that is permeating a limited movement while the main purpose of the bearing is to transmit load. There are some situations where bushings are used with the main purpose is load transmission, instead of a bearing (also named Plain Bearing) but in that case you will have more friction on a bushing compared to a bearing, harder to deal with misalignments, lower precision and lose of load transfer do to friction. A bushing is a bearing, but a bearing is not always a bushing. There is also a different when it comes to different forces that apply on the system. Bearings can be design to withstand forces from all directions.

The problem with ball bearings I learned in my engineering course is that they aren’t good at handling constant non motion radial load as only one point of the bearing is in contact with the outer and inner ring it can dent or scar them making them not ideal for applications where something isn’t moving often or is really heavy, for that you want to use needle or cylidrical/ conical bearings as the contact with the surface is larger, however they can be less efficient because of this. Also when installing you need to look at what part is rotating and install the bearing with tolerances accordingly because you don’t want the rings to slip on the part that isn’t moving, or crush the bearing which will cause premature failure. There’s a ton of pretty complicated calculations to figure out the loads and lifespan of them alongside what bearings should be used in what applications.

Overall good visuals, however I'd have welcome a deeper discussion on pro and con for each. Yes ratial and axial load where discussed yet not emphasised or explained enough. Plus it's missing the linear rails bearings, and discussing usage of multiple roller bearings to have axial and radial load support.

You missed an extremely common bearing type, the Journal bearing. Journal bearings rely on a pressurized film of oil to provide their rolling action, rather than balls or cylindrical rollers. Because this oil is a film, rather than a set of contact points, it has a much higher contact than balls or rollers, and allows for a far greater capability to handle various types of forces. Unfortunately, these bearings need a constant oil supply to actually function, usually provided by being pumped through a port on the inner race. To minimize damage when oil is not supplied, the outer race of the bearing is usually a shim made of a softer material than either what the shim clips into, or the inner race. When oil runs dry, the friction increases drastically, and the shim gets ripped out of its socket and forced to spin and scratch up, resulting in what mechanics usually call a "spun" bearing. Journal bearings are very nearly the only bearing type used inside the main chambers of an engine block; for bolting the crankshaft down, for bolting tie rods to the crankshaft, and to hold the tie rods to the pistons themselves, in the event that it makes enough back and forth friction to need a bearing.

@sayingnigromakesyoutubecry2647 Год назад

True. And also, in 2 strokes bikes, they use normal bearings. I think Needle ones. Strange!

@sayingnigromakesyoutubecry2647 Год назад

The answer is that in two strokes you don't have enough oil...

I knew someone who used to buy surplus military parts. I asked him once about some bearings he had. They were boxed, sealed and unused. He told me they were used in some type of missile, I believe the minute man or scud missile. He told me they had to be replaced every year because they were extremely high precision bearings and to insure the missile's accuracy they were replaced every year even if sealed and unused as surplus parts because the grease might start to get a bit stiff throwing off the missile's accuracy.

Tapered roller have been widely used in automobile's for many years. and are usually used on the front of the vehicle. and are placed in a hub and onto a spindle. and have the ability to be repacked with grease. or in the case of large truck's where gear lube is used. and regular bearings are also termed as bushings. and thrust bearings are also termed as Torrington bearings. and a couple of other types of bearings that were very lightly touched on in this video. were babbitt and clevite style bearings that are used in automobile engines.

As others have mentioned, hydrodynamic and aerodynamic bearings are not really addressed. There is also some confusion in the video about plain bearings and fluid bearings, I am pretty sure that one illustration used in fluid bearings was actually an engine main bearing, that is a plain bearing and also a hydrodynamic bearing. All plain bearings used in main, big end and little ends of modern car engines (and that is most automotive engines) are hydrodynamic bearings, making it arguably the most common type of bearing. Indeed, most plain bearings are hydrodynamic bearings, they are very reliable and once moving there is no surface-to-surface contact, the load being fully supported on a thin film of oil. Peak oil film pressures in modern cars are around 50,000 psi in big ends and 40,000 psi in mains (if memory serves), the oil pump does not provide this pressure, its only job is to ensure sufficient oil reaches all the bearings (and also cooling of components such as pistons), the hydrodynamic thrust is generated by the bearing itself through geometry, physics and behaviour of fluids. Notable other hydrodynamic bearings are the Michel thrust bearings (similar to the Kingsbury thrust bearing) used in ships to transmit all the thrust from the propeller to the hull. Previous to the Michel bearing, ships thrust bearings were much, much larger, unreliable and prone to overheat, the Michel bearing revolutionized the design of ships propeller shafts.

@tinuvarun5806 5 месяцев назад

He said that the magnitude of rolling friction is always less than the magnitude of sliding friction. Which one is easier to push, a ball or a box? Of course the ball. Because when you push it, it rolls, whereas the box slides. More friction is generated when pushing the box making it harder to push.
