wholesale high speed Self-lubricating bearing
Product details
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
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!
