Original versus Fake Bearings



Counterfeit or fake bearings are a serious problem by every manufacturer of bearing products.  Nowadays, it is almost impossible to spot the difference of the original bearings and the fake bearings.  Fake products ranges not just from designer clothing, luxury watches, hand bags and many others that are flooding the market, and what is more alarming is that even industrial products with safety-relevant issues like rolling bearings are also being counterfeited.
The fake bearings may even look the same as the original bearings even the brand name of who made it is also counterfeited.  One should be vigilant about this and don’t be easily fooled by fake products because poor quality bearings may result to dangerous and risky consequences for the end users.

Bogus Bearings causes Too Much Problem for Engineers
The flourishing of the fake bearing products causes too much concern and problem for every businesses and engineers as well.  Everyone in the bearing business is alarmed with this disturbing problem because a lot of news of counterfeit bearing products is distributed around the market.  Some engineers even experienced getting bogus bearings that has very poor quality and did not even last for an hour after fitting it into the machines.
What makes this too alarming is that counterfeiters are very good in reproducing original packaging and markings of the top bearing suppliers and one who is not professional in bearings may find it difficult to distinguished the fake bearings to the original bearings. Counterfeiting practices of bearings can be done by producing the exact copies of the legitimate brand imprints and markings of the famous bearing manufacturers and using second hand or used bearings that are re-conditioned so it will look good as new.  Other practices may include grounding or polishing the bearings to remove the pit marks and rust of the grease stains and oil. 

Some even simply remarked the bearing tolerances since the ordinary bearings are usually marked as P4, P5, and P6 class and others even altered clearance like the C3 clearance which is remade as a plain bearing or a plain bearing to C3 bearings.   You will be surprised that the lists go on and on when it comes to producing counterfeit bearings.  It is very alarming to note that counterfeiters can target any types of bearings. 

The fake may enter the market with the used bearings from the automotive back street and after market applications, wherein those who are less sophisticated and professional users are unable to determine that they are already fooled by scams.


OEM Bearings with wider lead times
Even the bogus bearings are getting better over the years; it even entered the precision bearing or OEM market where it usually suffered an extensive lead time.  Counterfeiters are able to produce copies that can run down from the industrial mill products which can often be sold mixed in with the originals.  Fake bearings which don’t meet the technical specification are always expected to have low quality and may fail quickly in delivering good performance. 
Spurious bearings create more economical loss and problems that may result to serious implications particularly on the critical safety applications.  Worst, it may even ruin the reputation of your business.


Spot the difference?
Distinguishing the fake from original bearings can be impossible for those who don’t have much experience and know-how in the technical aspects of the bearings.  More often than not, only the technical laboratory can confirm the authenticity of the bearings.  Most importantly, only the authorized distributors can assure legitimate and original products.  
Thus, it is highly recommended to buy bearings from the authorized distributor only.

What Is a Bearing?


A bearing is a mechanical device that helps in maintaining the moving section of an engine. The main function of a bearing is to confine an engine's motion while putting off the movement in an applied weight. The objective of this tool is to lessen the friction with a bare minimum of energy loss to simultaneously control the wearing and tearing of the engine or machine. Bearings are produced to support the thrust loads, radial loads, and or combined thrust-radial loads.
The two most popular forms of this tool are linear and rotary bearings. Linear bearing is used to allow movement in a straight direction. Say for example, your cabinet drawer is making use of this tool to assists the pulling of drawer in back and forth motion. Meanwhile, rotary bearing helps in moving around an object in a central spot. Like for example, wheel on a shaft rotates using this tool. Rotary bearings may include swinging and rotation in one direction.
Through swinging, this tool goes through a section of rotation. Other form of bearings uses different principle of motion depending on the design. A tool that uses a rolling element is called ball bearings and roller bearings. This rolling element carry load through placing a spherical element between two parts. This makes the spherical elements to tumble or roll with a slight sliding.
A fluid bearing is another common type of tool used. This tool functions by carrying a load either in a gas or liquid form. This tool is used when a procedure requires high precision loads and speeds because an actual ball bearing will quickly wear out if used in this application.
A magnetic bearing is used when a weight is carried by means of a magnetic field. It is often used in electrical meter to determine power consumption. It is also used to support a train which results in a lesser noise and smoother ride. This tool offers an extremely low friction and can perform work even without using lubrication. It can also function with vacuum but it is very expensive.
A flexure bearing is used if the weight element needs to turn. Usually, this tool is considered as a section that combines two other sections. An example of this tool is a door hinge. This tool is inexpensive and simple. It is also lightweight and creates little amount of resistance. The scope of movement is also limited and it cannot support a higher load.
A bearing is designed in a way that it can offer lesser friction and to support different types of loads. It also helps in providing precise engine or machine performance with varying speeds and loads.
