[Title]: Demand 7307 BEGBP used in elevator

I need 6000 Pcs 7307 BEGBP，nylon cage，the customer use two pieces face to face.

the speed of bearing is 1400 RPM, and it is for elevator, so need very high quality, if you find ready stock I need urgently, lower qty is ok too, but pls noted the quality grade, it's long term purchasing, so there's many big chance. 



I will take by airship, pls reply soon!
