Ningbo Yinzhou Zhengli Hydraulic Technology Co., Ltd. Yunnan Branch


Ningbo Yinzhou Zhengli Hydraulic Technology Co., Ltd. (long-term stock supply of Rexroth, Sao, Linde, Vickers and other hydraulic pump valves and accessories) We specialize in hydraulic parts overhaul and design and manufacture, hydraulic maintenance, hydraulic pumps, Overhaul of hydraulic motors, etc., long-term overhaul of imported parts (open circuit Piston pump, closed circuit piston pump, motor, valve block, distributor, cylinder). The repair experience for road machinery is particularly rich. Long-term professional maintenance ( pavers, road rollers, cement pump trucks, trailers, flatbed trucks, road mix trucks, excavators, cranes, cranes ) and other hydraulic systems and hydraulic components.
It adopts advanced hydraulic maintenance technology and has professional processing capability and testing technology. It has three high-power test benches, two closed system test benches and two hydraulic valve test benches. In addition to solving problems such as oil pan, cylinder block and plunger, especially solving hydraulic pumps, hydraulic motors, and controls. Core technology issues such as valves and their servo variables are particularly advantageous. From material selection and heat treatment (with material analysis, inspection equipment) to manufacturing to assembly. The durability of the product is close to the original imported level, so users can restore hydraulic components and system performance when they can't purchase parts.

Cylindrical Roller Bearing

Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Cylindrical Roller Bearings are designed to carry heavy radial loads. Our cylindrical roller bearings are made with a single row, two rows, or multi-rows of rolling elements to meet an application's radial load requirement. The radial Roller Bearing is available in many standard series and configurations, they are widely used in multiple industries. The combination of high load capacity, moderate speed rating, and industry interchangeability make it one of the most popular bearing designs. These cylindrical roller bearings are produced in ISO series metric, ABMA series metric and inch, journal type, Full Complement series, multi-row series, and cluster mill sizes. These bearings are dimensionally interchangeable to same numbered and sized bearings in the industry. Components of journal bearings and other standard series are made interchangeable with other manufacturer's components. Many mounting arrangements can be achieved with the multiple configurations available with the same load capacity for a given I.D., O.D., and width. Our cylindrical roller bearings can be manufactured in sizes from 3" bore diameter to 84" outside diameter. Internal radial clearances and cage designs can be engineered to your specific application when special applications are encountered.
