6900ZZ Shielded Deep Groove Ball Bearing

In the core equipment operation. Leveraging cutting-edge technological R&D and a rigorous quality control system, we've developed a comprehensive bearing product matrix that spans Stainless steel bearing, Ball bearing, Deep groove ball bearing, Non-standard bearing, Small bearing, and Water pump bearing. This portfolio delivers professional and reliable transmission solutions across diverse global industries.

 

The 6900ZZ shielded deep groove ball bearing, a premium offering in the Small bearing category, distinguishes itself through its classic design and exceptional performance. Its double dust cover (ZZ) shielding structure, crafted from high-strength stamped steel, is seamlessly integrated with the bearing's inner and outer rings via precision welding technology. Certified to IP54 protection standards, it forms a robust barrier against dust, debris, and other contaminants. Whether deployed in dusty mechanical processing workshops or challenging storage environments, it ensures the consistent operation of internal precision components, minimizing equipment maintenance frequency and downtime losses.

 

Engineered with high-carbon chromium bearing steel of equivalent quality to Stainless steel bearings, this product undergoes a series of meticulous processes, including vacuum quenching, tempering, and deep cryogenic treatment. These treatments elevate its surface hardness to HRC60 - 62, endowing it with exceptional wear and corrosion resistance. As a quintessential representative of both Ball bearing and Deep groove ball bearing technologies, it features precision-grade G10 steel balls paired with a classic symmetrical deep groove raceway design. Through extensive mechanical testing and simulation optimization, it has been validated to sustain radial loads of 0.9kN and axial loads of 0.35kN. With a friction coefficient as low as 0.006, it operates efficiently at high speeds, registering a vibration value ≤7.5m/s² and a noise level ≤42dB at 10,000r/min. This makes it an ideal choice for high-precision, high-speed transmission systems, meeting the operational demands of automated production lines, precision instruments, and other sophisticated equipment.

 

For projects with specialized requirements, our Non-standard bearing customization service offers comprehensive support from our team of professional engineers. Utilizing advanced CAD/CAM design systems and drawing on extensive industry experience, we provide tailored solutions that encompass material performance optimization, innovative sealing structures, and precise tolerance control. In micro water pump applications, the 6900ZZ shielded deep groove ball bearing has demonstrated remarkable resilience under simulated high-frequency start-stop cycles and continuous vibration. Achieving a dynamic load coefficient (C) of 1.1kN and maintaining a bearing clearance variation ≤0.007mm after 1500 hours of continuous operation, it matches the stability of dedicated Water pump bearings, ensuring long-term efficiency in micro water pump systems.

 

From the core machinery of industrial automation to the critical components of precision instruments, the 6900ZZ shielded deep groove ball bearing, with its outstanding performance, works in tandem with our complete product range to deliver reliable power for mechanical operations. This collaboration enables industries to embrace new heights of efficiency and stability.
