Shandong JinNai International Trade Co., Ltd.


Jinnai has a legacy of innovation since its inception 15 years ago.

Early on, Mr Song recognized that, in addition to conventional applications for bearings and other products,

steel balls could also be used to clean and finish the surfaces of metal objects.

Jinnai has also developed a range of ball products, from drill balls to those from exotic materials,

for diverse industries from automotive, aerospace and electronics.
