605ZZ Shielded Miniature Bearing 5×14×5mm

The 605ZZ shielded miniature bearing 5×14×5mm, as an outstanding representative of Small bearings, with its compact size of 5×14×5mm, can perfectly fit precision devices such as medical equipment and electronic instruments that have strict space requirements. 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. It has been verified by IP54 protection level test and can effectively block dust particles with a diameter of ≥0.1mm and splashing water droplets. Even in a dusty workshop environment or a storage place with high humidity, It can also ensure the cleanliness of the precision components inside the bearing, significantly reduce the risk of wear caused by impurity intrusion, and decrease the frequency of equipment maintenance and downtime. ​

This bearing is made of high-carbon chromium bearing steel of the same quality standard as Stainless steel bearing. It undergoes quenching, tempering and deep cryogenic treatment processes. 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 adopts the classic point contact rolling element design, combined with the symmetrical Deep groove raceway structure of Deep groove ball bearing. Through mechanical simulation and actual tests, it can withstand radial loads up to 0.85kN and axial loads up to 0.3kN. During operation, the friction coefficient is as low as 0.006. At a high-speed operation of 10,000 r/min, the vibration value is ≤7.5m/s² and the noise level is ≤42dB, providing stable and efficient power transmission for automated production lines, precision inspection equipment, etc. ​

If your project has special specification requirements, our Non-standard bearing customization service will provide an all-round personalized customization solution based on equipment parameters and working conditions, from material selection, sealing form to tolerance grade. In the application of water pump equipment, the 605ZZ shielded miniature bearing was tested under simulated high-frequency start-stop and continuous vibration conditions of the water pump. The dynamic load coefficient (C) reached 1.05kN. After continuous operation for 1200 hours, the change in bearing clearance was ≤0.008mm. It shows stable performance comparable to that of Water pump bearing, effectively ensuring the long-term efficient operation of small water pump systems. ​

From the microscopic precision instruments in the laboratory to the core equipment in industrial production, the 605ZZ shielded miniature bearing 5×14×5mm, with its outstanding performance, works hand in hand with our full range of main products to provide solid support for mechanical operation and help various industries embark on a new journey of efficiency and stability.
