1, About the lead time.
This depends on several factors, like Is the production schedule tight? Is there a corresponding model in stock, and is there enough of this model in stock? How many pcs of that model would be ordered?
Simply speaking, based on a 20' GP container load:
If the model your Preferred is | Sufficient stock | Lead Time |
Regular models | YES | Within 7 days |
Regular models | NO | Within 30 days |
Non-regular model | NO | About 50 days |
For accurate estimate, please contact with our sale stuff. Thanks.
2, Minimum order quantity.
For DGBB or Insert bearings, our minimum order quantity is one pallet, regardless of whether the order is for one model or several. But, for angular contact bearings, the MOQ is
ONE
piece.
