695ZZ Shielded Miniature Bearing 5×13×4mm

The 695ZZ shielded miniature bearing with dimensions of 5×13×4mm, with its extremely compact size of 5×13×4mm, has become a model in the field of Small bearings. Its exquisite shape perfectly matches the precise steering system of the micro drone gimbals, the complex transmission devices of smartwatches, and the core components of portable medical testing instruments. The double dust cover (ZZ) shielding structure is made of high-strength stamped steel and seamlessly integrated with the inner and outer rings of the bearing through precise laser welding technology. It has been certified with an IP54 protection level, which is like putting a solid armor on the bearing. Even in a mechanical processing workshop filled with metal debris or an outdoor working environment with sandstorms, it can keep dust and impurities out. Effectively reduce the maintenance costs caused by equipment wear and tear and minimize downtime losses. ​

In terms of material and process, this bearing selects high-carbon chromium bearing steel of the same grade as Stainless steel bearing. It undergoes multiple tempering processes such as vacuum quenching, tempering and deep cryogenic treatment. The surface hardness reaches HRC60-62, forming a tough and wear-resistant protective layer, and at the same time has excellent corrosion resistance. 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 professional mechanical testing and simulation optimization, it can stably bear a radial load of 0.7kN and an axial load of 0.25kN. During operation, the friction coefficient is as low as 0.006. At a high-speed running state of 12,000 r/min, the vibration value is ≤7m/s² and the noise level is ≤41dB, providing stable and efficient power output for high-precision and high-speed micro-transmission systems. ​

Facing special specification requirements, our Non-standard bearing customization service is led by a team of senior engineers, providing a full-process personalized customization solution from material performance optimization, sealing structure innovation to precise control of tolerance grades. In the application of micro water pump equipment, the 695ZZ shielded micro bearing has passed the rigorous test of simulating high-frequency start-stop and continuous vibration. The dynamic load coefficient (C) reaches 0.85kN. After continuous operation for 1200 hours, the change in bearing clearance is ≤0.006mm. It shows outstanding stability comparable to that of Water pump bearing, ensuring the long-term and efficient operation of the micro water pump system. ​

From the micro-precision operation of smart wearable devices to the key transmission links in the field of industrial automation, the 695ZZ shielded miniature bearing 5×13×4mm, with its outstanding quality, works hand in hand with its full range of main products to inject reliable power into mechanical operation and drive various industries towards a new realm of efficiency and stability.
