634-2RS Slim Sealed Miniature Bearing

In the field of precision transmission, every type of bearing is the key to ensuring the stable operation of equipment. Relying on our profound technical accumulation and strict quality control system, The construction covers Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non-standard bearing, Small bearing and Water pump bearing's full range of bearing product matrix provides professional and reliable transmission solutions for industrial users worldwide. ​

The 634-2RS ultra-thin sealed miniature bearing, with its unique "slim" design, has become the "slim pioneer" in the Small bearing family. Its exquisite dimensions can be easily adapted to various precision devices with strict space requirements, such as the core transmission components of micro medical devices and the compact structures of small electronic devices. The double-sided contact rubber seal (2RS) structure is made of high-performance fluororubber material and closely adheres to the inner and outer rings of the bearing through a precise molding process. It has been certified with an IP67 protection level and functions like a sturdy protective cover, effectively preventing the intrusion of dust, liquids and oil stains. Whether it is a damp laboratory environment or an industrial workshop with oil splashing, it can ensure the stable operation of the precision components inside the bearing, significantly reducing the risk of equipment failure and maintenance costs caused by contamination. ​

In terms of material, this bearing selects high-carbon chromium bearing steel of the same high quality 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 Ball bearing, it is equipped with precision grade G10 steel balls and combines 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 0.6kN and an axial load of 0.22kN. 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 ≤5.5m/s² and the noise level is ≤38dB, 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 be fully supported by a team of professional engineers. Relying on advanced CAD/CAM design systems and rich industry experience, we provide you with personalized customized solutions from material property optimization, sealing structure innovation to precise control of tolerance grades. In the application of micro water pump equipment, the 634-2RS ultra-thin sealed micro bearing has passed the rigorous test of simulating high-frequency start-stop and continuous vibration. The dynamic load coefficient (C) reaches 0.75kN. After continuous operation for 1200 hours, the change in bearing clearance is ≤0.005mm. It shows outstanding stability comparable to that of Water pump bearing, ensuring that the micro water pump system can operate efficiently for a long time. ​

From micro precision instruments to industrial automation equipment, 634-2RS ultra-thin sealed 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 high efficiency and stability.
