@shandongboss001: I have to admit, this is my first time seeing a bearing this big! Although I've spent years working in steel structure and storage tank manufacturing and have come across plenty of large industrial equipment, this one is outside my area of expertise. So I can't really explain what such a massive bearing is used for. Any experts here? Does anyone know what kinds of machines use bearings this large? #Bearing #MachineryManufacturing #IndustrialEquipment #HeavyMachinery #china
