16002

16002 is an ultra-thin wall deep groove ball bearing of the 1000 series, a miniature precision bearing specially designed for high-speed and light-load scenarios. It adopts a standardized ultra-thin structural design with core product specifications of inner diameter 15mm, outer diameter 32mm and width 8mm. The overall size is small and the structure is compact. The ultra-thin wall design greatly saves the installation space of equipment, adapts to the compact layout requirements of various small and precision equipment. In addition, the installation and disassembly operations are convenient without the assistance of complex tooling, which can effectively improve the assembly and maintenance efficiency of equipment.

The core components of the bearing are all precisely forged and processed with 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 multiple precision processing procedures such as forging, annealing, precision grinding and superfinishing, the bearing blank 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 can reach 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 operation, and meet the high-specification operation requirements of precision equipment. The bearing is equipped with a high-precision ground 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 main lubrication method of the 16002 1000 series bearing is lithium-based grease lubrication, with special lithium-based grease for high-speed bearings selected. 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 contact of metal 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 reduce 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 16002 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 6kN and rated dynamic load is 9.3kN. The bearing capacity accurately matches the light-load operation requirements and can stably cope with continuous light loads and intermittent micro-impact loads under high-speed operation. The bearing is exclusively designed for high-speed working conditions with excellent high-speed performance. The limiting speed can reach 17000r/min under the conventional working condition of grease lubrication. 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 16002 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 precision instrument industry (rotary support components of optical instruments, measuring instruments, small testing equipment and experimental analysis instruments), the motor manufacturing industry (spindle support of small DC motors, AC micro-motors, stepping motors and servo motors, perfectly adapting to the high-speed operation requirements of motors), the office automation equipment industry (paper feeding mechanisms and rotary transmission components of printers, copiers, scanners and shredders), the smart home industry (core rotary components of small fans, smart door locks, micro water pumps, air purifiers and small kitchen appliances), the electric tool industry (auxiliary rotary support components of small lithium electric tools, micro grinders and electric screwdrivers), the auto parts industry (precision support components of automobile on-board electrical appliances, micro motors, window lifting mechanisms and seat adjustment mechanisms) and the medical device industry (precision rotary components of small medical testing equipment, portable medical instruments and micro rehabilitation equipment), etc. At the same time, the bearing can also be adapted to civil and industrial light rotary equipment such as toy models, small transmission gear boxes and micro fans, 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 to meet the differentiated use requirements of conventional equipment and precision equipment.
