Hello marufrahman,
purchasing might need deep pockets!
Depending of the specific property and type of bearing you intend to test, you might just type >roller bearing testing< or >ball bearing testing< into your search machine and check for the convenient facility.
Regards
R.
please can you help us by suggesting which bearings you need to test, and what about the bearings needs to be tested?
Are the test requirements based on existing purchasing specifications, a problem you are trying to understand and correct, or perhaps some industry code?
What type of test do you want to perform on these ball bearings? Is it for quality control purposes where you are inspecting dimensional or operating characteristics? Or do you want to perform lifecycle testing?
Marufrahman:
You are being pretty secretive about bearing types, sizes, speeds, loads, actual application and the life you expect from the bearings. If you are buying relatively standard types and sizes of bearings from a reputable bearing manufacturer, you may not really need to test every different type of bearing to failure to have some confidence that they will work. The good manufacturers have tested thousands of these to have confidence in their own product, and to bring it to market. Standard bearings are more or less a commodity these days, but you may be wise not to buy from the lowest bidder or the neighborhood blacksmith. Are you life-cycle testing every other item on your product to the same rigor you are suggesting for the bearings? You might better spend that testing money on other things and aspects of your design, if you are worried about the real quality of your own product.
Are you the ball bearing manufacturer? Or are you performing in-house lifecycle testing as part of your acceptance QA of bearings from a supplier?
A big factor in rolling element bearing life is fatigue of the metal races/elements, and it is a statistical value that can be greatly affected by many factors such as material quality, heat treatment, surface roughness of the raceways/elements, operating conditions, lubrication conditions, etc. Since rolling element bearing life is usually a calculated statistical value, it is assumed that if the factors used in the analysis are appropriate for the application, and the bearing is manufactured using the prescribed materials, processes, dimensions/tolerances, etc, then the bearing product will deliver the anticipated operating life and reliability rate. Rolling element bearings of conventional design are rarely lifecycle tested, since the test procedure typically requires a long period of time, and there is a high level of confidence in the analysis approach commonly used.
There are a wide range of characteristics to test the robustness of a ball bearing. It is expensive to purchase and operate.
I suggest you develop a list of the performance characteristics, the bearing part number, and contact a service that does bearing testing. For example:
That's certainly possible and I don't mind if it never gets read by the OP. This site is a great repository for technical knowledge and highly visible from google. Someone else may find it helpful.
