German NU2226-E-M1-C3 bearing NU2226-E-M1-C3 model NU2226-E-M1-C3 price

NU2226-E-M1-C3 bearings are bearings that operate under sliding friction. Plain bearings operate smoothly, reliably, and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear; the oil film also has a certain vibration absorption capacity. However, the starting friction resistance is relatively high. The part of the shaft supported by the bearing is called the journal, and the part mating with the journal is called the bearing bush. The anti-friction material layer cast on the inner surface to improve the friction properties of the bearing bush surface is called the bearing lining. The materials of the bearing bush and bearing lining are collectively referred to as plain bearing materials. Plain bearings are generally used in high-speed and light-load operating conditions.

NU2226-E-M1-C3 bearing function and structure

Supports rotating shafts and components on the shaft, maintaining the normal working position and rotational accuracy of the shaft. Rolling bearings are easy to use and maintain, reliable in operation, have good starting performance, and offer high load capacity at medium speeds. Compared with plain bearings, rolling bearings have larger radial dimensions, poorer vibration damping capability, shorter service life at high speeds, and greater noise. The structure of a rolling bearing consists of the following parts: 1) Outer ring – installed in the bearing housing bore, generally does not rotate 2) Inner ring – installed on the journal, rotates with the shaft 3) Rolling elements – the core components of the rolling bearing 4) Cage – separates the rolling elements evenly to avoid friction. Lubricant is also considered the fifth major component of rolling bearings; it mainly serves functions such as lubrication, cooling, and cleaning.

NU2226-E-M1-C3 bearing features

1). Significant energy saving. Due to the motion characteristics of rolling bearings themselves, their friction is far less than that of plain bearings, reducing power consumption due to frictional resistance, thus achieving significant energy savings. From theoretical analysis and production practice, small ball mills using rolling bearings as main bearings can save up to 30%~35% of electricity, medium-sized ball mills can save up to 15%~20%, and large ball mills can save up to 10%~20%. Since ball mills are major energy consumers in production, this means considerable cost savings can be achieved. 2). Easy maintenance and reliable quality. Using rolling bearings eliminates complex maintenance processes with high technical requirements, such as smelting, casting, and scraping of Babbitt metal, as well as oil supply and water cooling systems, thereby greatly reducing maintenance workload. Moreover, since rolling bearings are manufactured by specialized producers, their quality is often guaranteed, bringing convenience to ball mill users.

NU2226-E-M1-C3 bearing lubrication

Mainly grease lubrication and oil lubrication. Grease lubrication is less prone to leakage, easier to seal, has a longer service life, is simple to maintain, and provides high oil film strength, but the friction torque is higher than with oil lubrication, making it unsuitable for high speeds. The amount of grease filled in the bearing should not exceed 1/2 to 1/3 of the bearing space; otherwise, excessive stirring of the lubricant will cause the bearing to overheat. Oil lubrication offers good cooling effects, but the sealing and oil supply devices are more complex. The viscosity of the oil is generally 0.12 to 0.2 cm²/s. High-viscosity oil is suitable for heavy loads and high operating temperatures, while low-viscosity oil is suitable for high speeds. Lubrication methods include oil bath lubrication, drop oil lubrication, oil mist lubrication, spray oil lubrication, and pressure oil supply lubrication. For oil bath lubrication, the oil level should not be higher than the center of the lowest rolling element. If the bearing is designed and the lubricant viscosity is selected according to elastohydrodynamic lubrication theory, the contact surfaces will be separated by an oil film. In this case, under stable load, the bearing life can be increased many times over. Modern machines, instruments, and other equipment are developing towards high speed, heavy load, precision, and lightweight designs, which puts forward many new requirements for rolling bearings, such as maintaining or even increasing the rated load while reducing size, adopting new technologies to improve processes, enhancing manufacturing precision, and reducing costs. General-purpose rolling bearings can hardly meet various requirements; dedicated bearings should be designed and manufactured for mass-produced machinery and equipment. While strengthening standardization, varieties should be increased, and the proportion of dedicated bearings expanded. The development of modern industry also requires special bearings for special operating conditions, such as bearings working at high speed, high temperature, low temperature, strong magnetic fields, or in media such as acids and alkalis.
