695ZZ Shielded Miniature Bearing

The 695ZZ shielded miniature bearing, as an outstanding representative in the field of Small bearings, with its exquisite size design, perfectly fits all kinds of miniature devices with strict space requirements. From the complex transmission system of smartwatches to the precise steering mechanism of micro drones, it can play a key role with its tiny body. Its double dust cover (ZZ) shielding structure is made of high-strength stamped steel and is closely combined with the inner and outer rings of the bearing through precise riveting process, forming a solid protective barrier. It has been certified with IP54 protection level and can effectively prevent dust, debris and other impurities from entering. Even in industrial workshops with flying dust or dusty storage environments, It can also ensure the cleanliness and stable operation of the precision components inside the bearing, significantly reducing equipment maintenance costs and downtime risks. ​

In terms of material, this bearing selects high-carbon chromium bearing steel of the same quality standard as Stainless steel bearing. It undergoes multiple precise processes such as vacuum quenching, tempering and deep cryogenic treatment. The surface hardness is as high as HRC60-62, and it has excellent wear resistance and 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 withstand 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 operation of 12,000 r/min, the vibration value is ≤7m/s² and the noise level is ≤41dB, providing stable and efficient power transmission for high-precision and high-speed micro-transmission systems. ​

If your project has special specification requirements, our Non-standard bearing customization service will provide you with all-round support by our professional engineer team. From optimizing material properties, innovating sealing structures to precisely controlling tolerance grades, we will provide personalized customization solutions based on equipment parameters and working conditions to ensure perfect compatibility between bearings and equipment. In the application of small Water pump equipment, the 695ZZ shielded miniature bearing has undergone simulated high-frequency start-stop and continuous vibration tests. The dynamic load coefficient (C) reaches 0.85kN. After continuous operation for 1200 hours, the change in bearing clearance is ≤0.006mm, demonstrating excellent stability comparable to that of the Water pump bearing. It effectively guarantees the long-term efficient operation of the small water pump system. ​

From micro precision instruments to industrial automation equipment, 695ZZ shielded miniature bearings, with their outstanding performance, work hand in hand with the full range of main products to provide a solid guarantee for mechanical operation and help various industries embark on a new journey of efficiency and stability.
