Phân biệt vòng bi (bạc đạn) Koyo chính hãng và hàng giả - phần 4

This is a series of experience videos to compare GENUINE (Real) and Counterfeit (Fake) bearings. 🎯 Volume 4 of this series is Koyo bearings. 📌 You should pay attention to the time this video was posted, because the technology of counterfeiting (Fake) will also follow the GENUINE (Real). So maybe this time is right, but next time will be different. 📚 If there is anything wrong or add more knowledge and experience, brothers and sisters in the profession know, just comment on the video so that you and I can learn more. 🖊 ✍ Thank you very much and always learn with a spirit of curiosity! 💡 ----------------------------------- Contact method: Transmission Official 📲 Phone: 0707 80 9292 📩 Email: [email protected] 👤 Facebook: https://www.fb.com/profile.php?id=100... #comparebearing #genuinebearing #fakebearing #koyobearing
