 Product details

Tongri bearing company specializes in manufacturing various hight -quality bearing and related produts .committed to becoming the benchmarch of chinese bearings companies , tomngri provides optimal solutions with adaced applications techology , consistent , reliable bearings produts and professional comphrehensive services to customers .
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts.

 

About us

   Shandong Tongri Power Science and Technology Co.,Ltd is a professional manufacturer for digit-control machine tool and paper-product equipment. In 1990, we began to manufacture textile bobbin and spiral paper tube with Hao Li Factory from Taiwan in the form of joint venture. In 1992 we developed semi-automatic conical and spiral paper tube production line which is sold throughout the whole country with our advanced technology, processing method, excellent product quality and high-level service.
    In 2006, we developed QZD-68 automatic conical paper tube production line after the absorption of German and South Korean technology. The new machine is coming with mechatronics to achieve low-labor, low-consumption, high-efficiency, high-quality paper tube production.
  In 2017, we developed all new automatic conical paper tube production line-TRZ-2017 after leaning from advanced experience and improving our current model. The efficiency has been improved to a whole new level. 
-We have almost 30 years machinery manufacturing and processing experience.
- We have nearly 20 years paper tube and bobbin manufacturing experience.
 -We'll provide you excellent package of paper tube production line and extensive experience.
