695-2RS Sealed Miniature Bearing 5×13×4mm

The 695-2RS sealed miniature bearing with dimensions of 5×13×4mm, as a refined model among Small bearings, perfectly fits various miniature devices with strict space requirements with its compact size of 5×13×4mm. In the core operating components of portable medical detection instruments and in the precise transmission systems of microelectronic devices, it can play a key role with its tiny size. Its double-sided contact rubber seal (2RS) structure, made of high-performance nitrile rubber material, is closely attached to the inner and outer rings of the bearing through precise molding process. It has been certified with IP67 protection level and can effectively prevent the invasion of dust, liquids and oil stains like a solid protective shield. 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, forming a dense wear-resistant layer, which has excellent wear resistance and corrosion resistance. As a member of the Ball bearing family, it is equipped with precision G10 steel balls and combines the classic symmetrical Deep groove raceway design of Deep groove ball bearing. After professional mechanical tests and simulation optimization, It can stably withstand radial loads of 0.75kN and axial loads of 0.28kN. During operation, the friction coefficient is as low as 0.005. 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. ​

Facing the requirements of special specifications and complex working conditions, our Non-standard bearing customization service is fully supported by a team of professional engineers. Relying on advanced CAD/CAM design systems and rich industry experience, we provide personalized customization solutions from material property optimization, sealing structure innovation to precise control of tolerance grades. In the application of micro water pump equipment, the 695-2RS sealed micro bearing has passed the rigorous test of simulating high-frequency start-stop and continuous vibration. The dynamic load coefficient (C) reaches 0.9kN. 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 that the micro water pump system can operate efficiently for a long time. ​

From the minute details of smart living to the core links of industrial production, the 695-2RS sealed miniature bearing 5×13×4mm, 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 helping various industries embark on a new journey of efficiency and stability.
