6900 Series Deep Groove Ball Bearings

Deep groove ball bearings are the most representative and widely used type of rolling bearing in the industrial field. They feature a simple structure, stable operation, and ease of maintenance. This series of bearings is primarily used to bear radial loads, but can also withstand certain axial loads in both directions, making them an indispensable core transmission component in various mechanical equipment.

Core Advantages

Low Friction, High Speed: The precision-ground deep groove raceways perfectly fit with high-precision steel balls, resulting in extremely low frictional resistance. This not only allows them to withstand extremely high limiting speeds but also effectively reduces energy consumption in equipment.

Smooth and Quiet Operation: Strict machining precision (e.g., P6/P5 grade) and surface roughness control result in low vibration and low noise during high-speed operation, making them ideal for applications with stringent noise reduction requirements.

Maintenance-Free/Low Maintenance: The robust and durable structure, combined with dust covers (ZZ) or rubber seals (2RS) and high-quality grease, effectively prevents impurities from entering and grease from leaking out, achieving long-term maintenance-free operation.
