lubrication/ high quality/ wholesale/ Cylindrical roller bearing
Product details
cylindrical roller bearings are available in many designs, series and sizes. The majority are single row bearings with a cage. High-capacity bearings, double row bearings, multi-row bearings, single and double row full complement bearings (without a cage) and split bearings.
Bearings with a cage can accommodate heavy radial loads, rapid accelerations and high speeds. Full complement bearings incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. Cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with a cage
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
Hebei Zengshan Intelligent Technology Co., Ltd. is a professional manufacturer of CNC machine tools, paper tube equipment, papermaking machinery, corrugated box equipment, and coating machinery. In 1990, we jointly produced textile tubes and spiral tubes with Taiwan Haoli Company. In 1992, we developed and launched a complete set of semi-automatic cone paper tubes and spiral paper tubes equipment. With advanced processing technology, processing methods, excellent product quality, and comprehensive services, our -products are sold to various parts of the country.-
In 2006, based on advanced technologies from Germany, South Korea, and other foreign countries, the QZD-68 fully automatic cone paper tube production line was developed. This machine adopts new technologies and processes of mechatronics integration, achieving the production of low labor, low energy consumption, high efficiency, and high-quality cone paper tubes.
In 2018, through communication and discussion- with numerous domestic customers, combined with international advanced experience, improvements and commissions were made to the original equipment. A new fully automatic conical paper tube production line ZSZ-2018 was launched, further improving the utilization rate of raw materials and gaining unanimous recognition from customers.
We have nearly thirty years of experience in mechanical manufacturing and processing.
We have nearly 20 years of experience in the production of paper and yarn tubes.
We provide you with excellent complete equipment and rich industry experience.
Quality is like a mountain, reputation is like a mountain, and commitment is like a mountain!
