Stainless steel outer spherical bearing
Outer spherical ball bearings are essentially a variation of deep groove ball bearings. Their most distinctive feature lies in the spherical outer diameter surface of the outer ring. This spherical surface can be precisely fitted into the corresponding concave spherical surface of the bearing seat, enabling effective self - centering.
Excellent Corrosion Resistance: Crafted from stainless steel, these bearings can effectively withstand the erosion of corrosive media like water, moisture, acids, and alkalis. They are highly suitable for harsh working environments characterized by humidity, dust, and chemical corrosion, such as those found in the food processing, chemical, and water treatment industries.
Superior Self - Centering Performance: The outer ring surface of the outer spherical bearing is spherical in shape. When paired with the bearing seat, it exhibits a certain degree of self - centering capability. This allows it to automatically compensate for axis deviations caused by installation errors, shaft deflection, or deformation. As a result, it ensures the normal operation of the bearing and minimizes additional stress and wear resulting from misalignment.
Easy Installation: Featuring a compact structure and often equipped with a built - in sealing device, outer spherical ball bearings can be directly installed on the shaft and within the bearing seat. There is no need for additional sealing or lubrication systems. This significantly simplifies the installation process and reduces both installation costs and maintenance workload.
Smooth Operation: The rolling elements of these bearings maintain excellent contact with the raceway, and the friction coefficient is relatively low. This ensures smooth operation even during high - speed rotation, with minimal vibration and noise. Consequently, it enhances the stability and reliability of the equipment's operation.
Moderate Load - Bearing Capacity: These bearings can bear a certain amount of radial and axial loads, meeting the mechanical transmission requirements under most general working conditions. However, compared to some large - scale heavy - duty bearings, their load - bearing capacity is relatively limited.
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.
