40+ YEARS EXPERIENCE 


With over 40 years experience of the bearing manufacturing, we know how to make good bearings.
We can produce high quality products at less cost consistently and efficiently.

OWN HEAT TEATMENT & COPPER CAGE PLANTS

 CONTROLLED QUALITY, CONTROLLED COST

With several heat treatment lines and a workshop of copper cage making, we have the following advantages over other suppliers:

-- We can flexibly adjust our production schedule, which is very advantageous in times of capacity constraints;
-- We can control the process more strictly to ensure the quality of our products;
-- And this also brings some advantages in terms of product cost. 
 

SAMPLES POLICY 

FREE SAMPLES AND SHIPPING

We are happy to send you free samples of our bearings for field testing. All transportation costs will be paid by us.

Please note: Depending on the model and value of samples, this policy may not apply!

Please contact our sales staff for details.

PACKING METHODS

1, Inner package
   Corrosion and Dust Proof PE plastic film  / bag packing + Tube packing, or Wrapping  tape for larger bearings

2, Outer package
    Corrugated carton + Wooden pallet 

 

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.

  
3, If you don't know which model is the right choice...
  
We would like to give you some advise if you like, according to the real situation and demand of your local market. Our purpose is to help you to get proper and right models for your customers, so that you would make a better sales and income finally.
