The 6900 deep groove ball bearing represents the pinnacle of rotational mechanics, meticulously crafted to eliminate friction and elevate the operational efficiency of your advanced machinery. When handling this component, the immediate tactile feedback is one of absolute rigidity and a flawless metallic finish, a direct testament to the premium GCr15 bearing steel utilized in its construction. During operation, the bearing emits a barely perceptible, uniform hum—an acoustic profile achieved through optimized raceway geometry and stringent Z1/Z2 dampening standards. This exceptional vibration control ensures that sensitive electronic drives, optical lenses, and precision medical instruments remain completely undisturbed by mechanical resonance, allowing your final products to function with absolute precision.
By integrating this specific bearing into your manufacturing assemblies, you actively mitigate the risk of premature equipment failure and costly downtime. The meticulously engineered internal geometry distributes radial and axial loads evenly across the rolling elements, preventing localized wear and thermal expansion even under continuous, high-speed duty cycles. Whether deployed in automated robotic joints or intricate office machinery, the seamless glide of the internal steel balls against the micro-polished raceways dramatically reduces energy consumption and thermal output. Consequently, your end-products will benefit from extended maintenance intervals, lower operational temperatures, and a significantly enhanced lifespan, ultimately protecting your brand's reputation for reliability in highly demanding industrial sectors.

Achieving mechanical harmony in compact spaces requires components that do not compromise on structural integrity or kinetic fluidity. Our 6900 bearings are engineered to deliver precise motion control while enduring the most rigorous industrial cycles, solving the common challenges of heat generation and component fatigue.
Frictionless Rotational Dynamics: The micro-polished raceways significantly reduce rolling resistance, allowing your motors to achieve peak efficiency with minimal power draw and extending battery life in portable devices.
Thermal Dissipation Excellence: Carefully selected steel alloys and optimal internal clearances (C0/C2/C3) prevent dangerous heat accumulation during continuous, high-speed operations.
Acoustic Management: Manufactured to strict Z1 and Z2 noise levels, ensuring your final consumer electronics or medical devices operate with whisper-quiet precision.
Versatile Lubrication Retention: Advanced sealing technologies lock in specialized greases, preventing dry friction and shielding internal rolling elements from abrasive particulates.
Structural Resilience: High dynamic (3.20 kN) and static (1.50 kN) load ratings ensure the bearing resists deformation under sudden mechanical shocks or sustained operational stress.
Understanding the exact technical capabilities of your components is vital for successful product integration. The 6900 series is built upon six foundational dimensions of engineering excellence, ensuring it meets the stringent demands of modern manufacturing.
Maintaining an exact 10x22x6 mm standard footprint, this component is subjected to multi-stage optical and mechanical inspections to guarantee flawless integration into your assemblies.

The selection depends entirely on the environmental conditions of your application. The ZZ (metal shield) configuration is optimal for clean, high-speed environments where friction must be minimized, allowing operational speeds up to 30,000 RPM. Conversely, the 2RS (rubber seal) provides superior, airtight protection against moisture and fine dust, making it ideal for exposed or harsh environments. However, the rubber contact limits the maximum speed to 20,000 RPM due to slightly increased friction.
Yes. The optimized deep groove architecture is specifically designed to accommodate substantial radial loads (up to 3.20 kN dynamically) while also supporting moderate axial loads in both directions. This dual-load capacity makes the bearing highly versatile for electric motors, robotic joints, and drive shafts where multi-directional forces are frequently present during operation.
Higher ABEC grades (such as ABEC-3 and ABEC-5) indicate significantly tighter tolerances in the bearing's physical dimensions and internal geometry. For your manufactured products, this translates directly to less mechanical runout, smoother rotation, and drastically reduced noise at high speeds. If you are manufacturing high-precision medical devices, aerospace components, or optical instruments, upgrading to a higher ABEC grade is crucial for ensuring absolute operational accuracy.
While our standard pre-greased bearings operate flawlessly within a broad range of -20°C to +120°C, we offer specialized lubrication profiles for extreme thermal conditions. Depending on your specifications, we can inject custom high-temperature synthetic greases or low-viscosity, low-temperature oils tailored to your exact thermal requirements, effectively preventing lubricant breakdown, carbonization, and mechanical seizing.
Absolutely. We offer comprehensive OEM branding services designed to integrate seamlessly with your supply chain. This includes precision laser etching of your company's specific part numbers, logos, or tracking codes directly onto the bearing's outer ring or metal shields. Furthermore, we provide customized, private-label packaging solutions to facilitate easier inventory management and reinforce your brand identity in the final assembled machinery.
