16004

16004 is an ultra-thin wall deep groove ball bearing of the 1000 series (16000 sub-series), a precision miniature bearing adapted to high-speed and light-load scenarios in the industrial field. It adopts a standardized ultra-thin structural design with core product specifications: inner diameter 20mm, outer diameter 42mm and width 8mm. The overall structure is compact and lightweight, and the ultra-thin wall design maximizes the saving of equipment installation space, adapting to the compact layout requirements of various small and precision equipment. In addition, it is easy to install and disassemble without the assistance of complex tooling, effectively improving the assembly efficiency of equipment and the convenience of later maintenance.

The core components of the bearing are all precisely processed and made of GCr15 high carbon chromium bearing steel. As a high-quality special steel for bearings, it has excellent hardenability, surface hardness, wear resistance and fatigue resistance. After the bearing blank is processed through multiple precision procedures such as forging, annealing, precision grinding and superfinishing, it is subjected to professional heat treatment processes of quenching and low-temperature tempering, so that the surface hardness of the bearing raceways and steel ball rolling elements reaches HRC60-64, and the internal metallographic structure is uniform and stable. It can effectively resist abrasion, micro-impact and fatigue damage under high-speed operation, ensure the precision stability and service life of the bearing during long-term high-speed continuous operation, and meet the high-specification operation standards of various precision equipment. The bearing is equipped with a high-precision cage, mainly made of engineering plastic or stamped steel, with a light structure and accurate positioning. It can stably separate the rolling elements, reduce friction, collision and jamming between rolling elements during high-speed operation, lower the noise and vibration of equipment operation, and further improve the smoothness and stability of the bearing's high-speed operation.

In terms of lubrication configuration, the standard lubrication method of the 16004 1000 series bearing is lithium-based grease lubrication, equipped with special lithium-based grease for high-speed bearings as standard. The grease has excellent adhesion, high and low temperature adaptability and shear resistance, and can be used stably under conventional working conditions of -30℃ to 120℃. After filling, it can form a uniform and dense lubricating protective film between the bearing raceway and rolling elements, completely isolate the direct friction of metal contact surfaces, greatly reduce the friction coefficient under high-speed operation, and reduce component wear. At the same time, the grease has good sealing retention, is not easy to lose during high-speed operation, and has a long maintenance cycle, which can effectively control the daily maintenance cost of equipment. If the equipment is in special working conditions such as ultra-high speed and high temperature, the oil lubrication method can be replaced according to actual use needs to further improve the heat dissipation effect and high-speed adaptability of the bearing and meet the operation requirements of special scenarios.

As a classic type of deep groove ball bearing, the 16004 can bear both radial load and slight bidirectional axial load at the same time, adapting to various transmission scenarios of light-load composite loads. Its rated static load is 9.8kN and rated dynamic load is 15.8kN, with a bearing capacity accurately matching the light-load operation requirements, which can stably cope with continuous light loads and intermittent micro-impact loads under high-speed operation. The bearing is specially designed for high-speed working conditions with excellent high-speed performance. The limiting speed can reach 13000r/min under the conventional working condition of grease lubrication, and can be increased to 18000r/min if oil lubrication is adopted. The actual service speed can be flexibly adjusted according to the installation accuracy, working condition environment and load size of the equipment. If the equipment installation accuracy reaches P6/P5 grade and the load is light, it can be used close to the limiting speed. On the whole, it is suitable for ultra-high speed to high-speed light-load operation scenarios and is a core supporting component of high-speed precision miniature equipment.

With the core advantages of ultra-thin and lightweight, excellent high-speed performance, high operation precision and strong adaptability, the 16004 ultra-thin deep groove ball bearing of the 1000 series is widely used in small and precision equipment in many industries. Its core application fields include the motor manufacturing industry (spindle support of small DC motors, AC micro-motors, stepping motors and servo motors, adapting to the high-speed operation requirements of motors), the precision instrument industry (rotary support components of optical instruments, measuring instruments, small testing equipment and experimental analysis instruments), the general machinery industry (core support of small fans, micro water pumps and precision transmission gear boxes), the office automation equipment industry (paper feeding mechanisms and rotary transmission components of printers, copiers and scanners), the 3C electronics industry (precision rotary components of small digital equipment and smart hardware), the auto parts industry (precision support of automobile on-board electrical appliances, micro motors and window lifting mechanisms), and the medical device industry (precision rotary components of small medical testing equipment and portable medical instruments). At the same time, it can also be adapted to civil light rotary equipment such as toy models and small electric tools, and is a miniature precision support component with a wide application range in industrial production and civil manufacturing. According to the precision requirements of the equipment, different precision grades such as P0 (general precision), P6 (high precision) and P5 (ultra-high precision) can be flexibly selected, and different sealing forms such as open type, ZZ dust cover and 2RS sealing ring can also be selected as needed to meet the differentiated use requirements of different equipment and different working conditions.
