62200 Deep Groove Ball Bearings

The 62200ZZ is a widely used widened single-row deep groove ball bearing in the industrial field, belonging to the standard 622 series precision bearings. Featuring compact structure, high speed, low friction and enhanced load capacity, this bearing is extensively applied in general motors, precision instruments, fans, water pumps, small mechanical equipment and automated accessories. Equipped with double-sided ZZ metal dust shields, the 62200ZZ provides excellent dustproof performance and stable long-term operation under normal working conditions. It serves as a core basic component for small and medium-sized transmission equipment and is one of the most in-demand standard bearing models for industrial procurement.
1. Product Structural Characteristics
Manufactured in accordance with international standard deep groove ball bearing design, the 62200ZZ consists of five core components: inner ring, outer ring, precision steel balls, pressed steel cage and double-sided metal dust shields. It features a compact structure, easy installation and disassembly, and strong universal compatibility. The standard dimensions are 10mm inner diameter, 30mm outer diameter and 14mm width. Compared with the ordinary 6200 bearing, the widened design greatly improves load-bearing capacity. The single unit weight is approximately 44g, and the lightweight structure effectively reduces equipment operating load and energy consumption.
The bearing is equipped with 9 precision steel balls with a diameter of 6.35mm. The evenly arranged steel ball structure uniformly distributes radial load and bidirectional slight axial load, effectively avoiding local stress concentration and abnormal wear. The standard R chamfer of 1mm meets international mounting standards, ensuring high tolerance and convenient assembly for conventional shaft seats. The double-sided ZZ closed metal shield structure effectively blocks dust, debris and particulate impurities from entering the bearing interior, while locking internal lubricating grease to prevent grease loss and dry deterioration. It requires minimal maintenance and adapts to dust-free and lightly dusty industrial environments. In terms of speed performance, the grease lubrication limit speed reaches 13000 r/min, and the oil lubrication limit speed is up to 17000 r/min, fully meeting the high-speed operation requirements of various mechanical equipment.
2. Core Material and Process Advantages
The 62200ZZ bearing is made of high-purity GCr15 bearing chrome steel, the premium universal material for industrial bearings. Adopting multiple precision processes including quenching, tempering and superfine grinding, the finished bearing features uniform hardness, outstanding wear resistance and excellent fatigue resistance. It can withstand long-term high-frequency operation and alternating load without deformation, peeling or jamming failures. The material possesses stable rust resistance and high-temperature resistance, maintaining consistent performance under conventional working temperatures and offering a far longer service life than ordinary carbon steel bearings.
The inner and outer ring raceways are processed by ultra-precision grinding technology, achieving high precision and ultra-smooth surface. Combined with finely polished steel balls, the bearing delivers extremely low friction coefficient, quiet and stable operation, and lower energy consumption. The matched pressed steel cage has high toughness and anti-deformation performance, which accurately fixes the spacing of steel balls and prevents ball offset and collision during high-speed rotation, ensuring stable operation accuracy. The interior is filled with high-temperature resistant long-life lubricating grease, which is not easy to deteriorate or leak during high-speed operation, maintaining stable lubrication for a long time and reducing equipment operation and maintenance costs.
