German Phoenix bearings Phoenix models Phoenix prices

Phoenix bearings are precision mechanical components that convert sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses. Rolling bearings generally consist of four parts: an inner ring, an outer ring, rolling elements, and a cage. The inner ring fits onto the shaft and rotates with it; the outer ring fits into the bearing housing and provides support; the rolling elements are evenly distributed between the inner and outer rings by the cage, and their shape, size, and quantity directly affect the performance and service life of the rolling bearing; the cage ensures even distribution of the rolling elements, guides their rotation, and provides lubrication.

Phoenix bearing functions and structure

Supports rotating shafts and components mounted on them, maintaining the shaft's normal operating position and rotational accuracy. Rolling bearings are easy to use and maintain, reliable in operation, have good starting performance, and offer high load capacity at medium speeds. Compared to plain bearings, rolling bearings have larger radial dimensions, poorer vibration damping, shorter service life at high speeds, and generate more 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 shaft journal, rotates with the shaft 3) Rolling elements – the core component of the rolling bearing 4) Cage – separates the rolling elements evenly to prevent friction. Lubricant is also considered the fifth major component of a rolling bearing, primarily serving functions such as lubrication, cooling, and cleaning.

Phoenix bearing features

1). Significant energy savings. Due to the motion characteristics of rolling bearings, their friction is far lower than that of plain bearings, reducing power consumption caused by frictional resistance, thus achieving significant energy savings. Theoretical analysis and production practice show that small ball mills using rolling bearings for main bearings can save 30%~35% of electricity, medium-sized ball mills can save 15%~20%, and large ball mills can save up to 10%~20%. Since ball mills are major energy consumers in production, this translates into substantial cost savings. 2). Easy maintenance and reliable quality. Using rolling bearings eliminates complex and highly technical maintenance processes such as smelting, casting, and scraping Babbitt metal, as well as oil and water cooling systems, significantly reducing maintenance workload. Moreover, since rolling bearings are manufactured by specialized producers, their quality is often guaranteed, providing convenience for ball mill users.

Phoenix bearing lubrication

Mainly grease lubrication and oil lubrication. Grease lubrication offers less leakage, easier sealing, longer service life, simpler maintenance, and higher oil film strength, but has higher friction torque than oil lubrication and is not suitable for high-speed applications. 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 may cause overheating. Oil lubrication provides better cooling, but requires more complex sealing and oil supply devices. The viscosity of the oil is generally 0.12 to 0.2 cm²/s. Higher viscosity oils are recommended for heavy loads and high operating temperatures, while lower viscosity oils are suitable for high speeds. Lubrication methods include oil bath, drip feed, oil mist, spray, and pressure-fed lubrication. In oil bath lubrication, the oil level should not exceed the center of the lowest rolling element. If the bearing and lubricant viscosity are designed according to elastohydrodynamic lubrication theory, the contact surfaces will be separated by an oil film. Under stable load conditions, this can significantly extend bearing life. Modern machinery and instruments are developing towards higher speeds, heavier loads, greater precision, and lighter weight, imposing new requirements on rolling bearings, such as maintaining or even increasing rated loads while reducing size, adopting new technologies to improve manufacturing processes, enhancing precision, and lowering costs. Standard rolling bearings can hardly meet diverse requirements; therefore, dedicated bearings should be designed and manufactured for high-volume equipment, expanding varieties and increasing the proportion of specialized bearings while strengthening standardization. Industrial development also requires special bearings for extreme conditions, such as those operating at high speeds, high or low temperatures, strong magnetic fields, or in acidic or alkaline media.
