Even though you are not familiar with machinery or related equipments, when you think of engine, you may think it must be one of most important parts among whole automotive parts. What about bearing? If you have expert knowledge, it would be hard to imagine straight what actually ‘bearing’ is and how important it is unlike engine. However, you will astonish to know how engine bearing works and how it is important for automotive industry.

Engine bearings do many things.

They support moving parts like crankshafts and connecting rods, but they also play a role in determining an engine's oil pressure and protect the crankshaft from being damaged by micron-sized particles. Improper bearing selection and or sizing can result in problems ranging from poor oil consumption to all-out, catastrophic engine failure. Ensuring that the correct bearing size, and therefore proper clearances are selected, can be accomplished relatively easily and for surprisingly little money.

Plain, or sleeve, bearings are the most common type used today. Such bearings come in half-shell-shaped pairs that, when matched together at ...
... their parting faces, encompass a crankshaft's main journals and rod journals 360 degrees. Bearings can be made of a variety of different materials and always consist of a soft and a hard material cast, sintered or bonded to one another. Bearing material choice affects factors such as engine longevity, corrosion resistance and the ability to withstand fatigue and occasional detonation through increased load capacities. Babbitt, copper-lead alloy and aluminum are a few of the most widely used surface-coating materials of recent years. No matter which material is selected, all three are coated on top of a low-carbon, hardened steel backing-the material that makes up a good portion of the bearing shell, gives it its shape and receives the brunt of the load. Such coatings are applied in approximately 0.01-0.02-inch layers.

Various kinds of engine bearings

Generally bearing falls into three kinds: White metal, Kelmet bearing, aluminum bearing. White metal is made of tin, lead, antimony and zinc and it has corrosion resistance and soft which makes easy for taming process and reclamation. Kelmet bearing is made of copper and lead alloys and it is suitable to be used for high speed / high-load engine due to excellence in fatigue resistance. However kelmet bearing has higher hardness relatively than white metal, it needs case hardening on crank journal and surface of pin. Lastly, aluminum bearing is made putting Aluminum and tin alloy on steel sheet. Its taming and reclamation is in the middle of white metal and kelmet, it has been frequently used due to its superior fatigue resistance.

Adaptation to the technology is vital

As one of the most important core part of automobile, engine bearing is a precision part comprehending all of metallurgical and mechanistic factors. Having a wide range product for multipurpose, motor engine bearing products should show its accurate and perfect quality according to its need. Companies manufacture some of the most modern equipment in automation, proving to be one of the most flexible processes for producing components that are strong, reliable and intricate.
