How to distinguish between genuine and fake SKF bearings
Thread Content
Dear experts, for the past 20 years, our company has used SKF C 2218 K bearings in its compressors – these are bearings with retainers and 19 balls. Very durable. When this bearing was purchased again this year, it had 16 balls, and after being installed in the unit and operated for 1000 hours, it broke apart. May I ask which expert has encountered such a situation? Thank you
Which expert has encountered this? Please advise. Thank you
If you don’t understand bearings, as you said, there are 3 fewer balls; the diameter should remain the same, but the clearance increases, and factors such as the force applied also change. Why not ask why there are 3 fewer balls?
It’s advisable to consult the SKF bearing manufacturer. To be honest, there are many agents in the market, and a lot of fake products are available. First, it’s important to confirm whether the product is genuine; if it is, then discuss with SKF’s technical staff the implications of having 3 fewer balls and what the purpose of that might be
Most bearings bought these days are fake; it’s practically impossible to find genuine SKF bearings in China
True and false, false and true. . The Chinese are too amazing; it’s impossible to shout at them! ! !
I checked the official website and found that C 2218 K and 2218K are two different bearings; you can check it on the official site at http://www.skf.com/cn
Purchasing from dealers listed in the SKF catalog generally ensures that the products are authentic. Install an SKF app, take photos of the product upon receipt as required, and upload the contract or invoice to have an official verification of its authenticity. At the two companies I worked for, the procurement staff only cared about comparing prices; as a result, everything purchased was fake. It wasn’t until something serious happened that we realized it.
Our company’s equipment isn’t reliable either; we can’t control production when it comes to procurement! There’s no way!
Just contact the SKF agent; they can provide everything needed to determine authenticity, and all relevant information will be available, provided that you’re willing to pay for their bearings
