  A self-lubricating sintered bearing is a metallic component with high porosity (20-25% in volume), impregnated in a lubricant oil. The oil contained in the porosity provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. Self-lubrication allows this type of sliding bearing to work under hydrodynamic conditions, resulting in a very low friction coefficient.
Self-lubricating sintered bearings have some advantages compared to
other types of dry sliding bearings:
- Reliability. The constant oil presence eliminates the risk of seizure, and allows the bearing to work during thousands of hours without wear.
- Economy. Maintenance-free, no need for lubricants.
- Performance. Able to work under loads of up to 10 MPa, and speeds up to 5 m/s. The maximum working PV is is the range of 5 MPa·m/s, but can be surpassed in special cases. The dimensional precision is very high (up to IT 5 in diameter), and produces extremely low noise.
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.
Product advantage
  Shandong Tongri Power Science and Technology Co.,Ltd focus on high level equipment manufacturing;supported by digit control and industrial automation technology. We encourage our engineering staff to be creative at all times.
  High quality, rare equipment includes fully hydrostatic, digit-milling machine TK6918*120 and gantry,digit-control boring-milling machine XK2750*220, which can guarantee our high quality manufacturing.
  Science and technology is the first productivity. The design team is the core of modern enterprise. We have 7 senior technician and the team have nearly 20 national intellectual property patents (includes 4 invention patents)and it is still growing.
  Our managing team has more than 20 years experience, which guarantee us the continuous development.
  We focus on high-end products, highest standard of this industry. To be the best is our goal forever.

Auto Parts (auto parts) constitute the entire automotive respective units and services in the car of a product.
With the auto parts processing market competition becomes more intense, deeply rooted concept of environmental protection, as well as escalating technology and applications, international auto parts Machining Parts industry in recent years, showing the development of the following characteristics:
â‘ auto parts processing systems supporting the modular supply trends in the ascendant
â‘¡ auto parts procurement process of globalization
â‘¢ auto parts processing industry transfer speed
Many kinds of auto parts, car brand is now more and more, more and more types of vehicles. Commercial vehicles and passenger cars can be divided into two types, which refers to a passenger vehicle less than nine seats to sit (including the driver bits), with the primary purpose passenger vehicles. Specifically, the passenger car that is divided into the basic passenger car, MPV car, SUV and other vehicles such as pickups and other vehicles.
