624-2RS Sealed Micro Bearing 4×13×5mm

In the microscopic realm of industrial transmission, each bearing serves as the linchpin for ensuring seamless equipment operation. Leveraging our profound technological expertise and stringent quality control protocols, we've established a comprehensive product matrix encompassing Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non-standard bearing, Small bearing, and Water pump bearing. This portfolio is meticulously crafted to deliver professional and reliable transmission solutions across diverse industries worldwide.​

 

The 624-2RS sealed miniature bearing, with its precise dimensions of 4×13×5mm, stands as an exemplar within the Small bearing category. Its double-sided contact rubber seal (2RS) structure, fabricated from high-performance fluororubber, adheres seamlessly to the bearing's inner and outer rings via a precision molding process. Boasting an IP67 protection rating, it functions as an impenetrable armor, effectively repelling dust, liquids, and oil contaminants. Whether deployed in humid, dusty food processing facilities or oil-splattered mechanical manufacturing lines, it safeguards the integrity of internal precision components, significantly reducing the risk of equipment failure and associated maintenance costs due to contamination.​

 

Engineered with high-carbon chromium bearing steel of equivalent quality to Stainless steel bearings, the 624-2RS undergoes a series of meticulous processes, including vacuum quenching, tempering, and deep cryogenic treatment. This results in a surface hardness of HRC60 - 62, forming a dense wear-resistant layer that offers exceptional abrasion and corrosion resistance. As a distinguished member of the Ball bearing family, it features precision-grade G10 steel balls paired with the classic symmetrical Deep groove raceway design characteristic of Deep groove ball bearings. Rigorous testing in professional mechanical laboratories, coupled with advanced computer simulations, has verified its ability to withstand a radial load of 0.6kN and an axial load of 0.22kN. With a friction coefficient as low as 0.004, the bearing operates with remarkable efficiency, maintaining a vibration value ≤6m/s² and a noise level ≤40dB even at high rotational speeds of 15,000 r/min. This makes it an ideal choice for powering micro transmission systems with exacting precision requirements, such as the steering mechanisms of micro unmanned aerial vehicles and the core transmission components of smart wearable devices.​

 

For projects with unique specification demands, our Non-standard bearing customization service offers tailored solutions. Our team of professional engineers, leveraging state-of-the-art CAD/CAM design systems and extensive industry experience, provides comprehensive personalized services. From optimizing material properties and innovating sealing structures to precisely customizing tolerance grades, we ensure a perfect fit for your specific needs. In micro water pump applications, the 624-2RS sealed micro bearing has demonstrated outstanding resilience. Subjected to rigorous tests simulating high-frequency start-stop cycles and continuous vibration, it achieves a dynamic load coefficient (C) of 0.75kN. After 1200 hours of continuous operation, the bearing clearance variation remains ≤0.005mm, showcasing stability on par with Water pump bearings. This ensures the long-term, stable, and efficient operation of micro water pump systems.​

 

From the precise operations of microscopic instruments to the core transmissions of industrial automation equipment, the 624-2RS sealed miniature bearing, with its exceptional performance, collaborates seamlessly with our full range of core products. Together, they provide a robust foundation for mechanical operations, propelling industries towards new frontiers of efficiency and stability.
