686-2RS Sealed Miniature Bearing 6×13×5mm

In the precise world of industrial transmission, every bearing is the core code for the stable operation of equipment. Relying on our profound technical accumulation and strict quality control, Construct covering Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non-standard bearing, Small bearing and Water pump bearing's comprehensive bearing matrix unlocks efficient transmission solutions for various industries worldwide. ​

The 686-2RS sealed miniature bearing 6×13×5mm, as a leader in the Small bearing field, precisely fits the compact size of 6×13×5mm for miniature devices with strict space requirements. From the precise drive unit of smart headphones to the joint transmission structure of micro-robots, it can exert tremendous energy with its tiny size. Its double-sided contact rubber seal (2RS) structure, made of high-performance fluororubber material, is closely fitted with the inner and outer rings of the bearing through advanced molding technology. It has passed the IP67 protection level certification, like building an impregnable barrier, which can effectively prevent dust, liquids and oil stains. Even in a humid food processing workshop, Even an electronic assembly production line covered with debris can ensure that the precision components inside the bearings are not disturbed, significantly reducing the probability of equipment failure caused by contamination and greatly lowering maintenance costs and downtime. ​

In terms of material, this bearing selects high-carbon chromium bearing steel of the same high standards as Stainless steel bearing. It undergoes triple tempering including vacuum quenching, tempering and deep cryogenic treatment. The surface hardness reaches HRC60-62, forming a dense wear-resistant layer and having extremely strong anti-wear and anti-corrosion performance. As a member of the Ball bearing family, it is equipped with precision grade G10 steel balls and combined with the classic symmetrical Deep groove raceway design of Deep groove ball bearing. After repeated tests in professional mechanics laboratories and optimization through computer fluid mechanics simulation, It can stably bear radial loads of 0.85kN and axial loads of 0.32kN. During operation, the friction coefficient is as low as 0.004. At a high-speed operation of 15,000 r/min, the vibration value is ≤6m/s² and the noise level is ≤40dB, providing stable and efficient power transmission for high-precision and high-speed micro-transmission systems. It meets the extremely strict requirements for operational accuracy in precision optical instruments, semiconductor manufacturing equipment, etc. ​

When faced with the requirements of special specifications and complex working conditions, our Non-standard bearing customization service responds immediately. Relying on advanced CAD/CAM design systems and rich industry experience, our professional engineering team provides one-stop personalized solutions, ranging from material property optimization, sealing structure innovation to precise customization of tolerance grades. In the application of micro water pump equipment, the 686-2RS sealed micro bearing has undergone rigorous tests simulating high-frequency start-stop and continuous vibration. The dynamic load coefficient (C) reaches 1.0kN. After continuous operation for 1500 hours, the change in bearing clearance is ≤0.005mm. It shows outstanding stability comparable to that of Water pump bearing, ensuring the long-term stable and efficient operation of the micro water pump system. ​

From the minute details of smart living to the core areas of industrial manufacturing, the 686-2RS sealed miniature bearing 6×13×5mm, with its outstanding performance, works hand in hand with the entire series of main products, like a precisely coordinated gear set, injecting reliable power into mechanical operation and driving various industries towards an efficient and stable future.
