6906-2RS Deep Groove Ball Bearing 30x47x9 mm | Standard Series | Double Rubber Sealed
This metric bearing combines the universal deep groove design with full-contact rubber seals, making it suitable for environments where exposure to particulates or humidity is a concern. It supports both radial and moderate axial loads, delivering smooth and quiet operation in continuous-duty applications. Its standardized dimensions ensure easy integration and replacement across various industrial platforms.

Suited for industrial, automotive, and machinery applications requiring dependable sealing and durable performance:
Two integrated low-friction rubber seals provide reliable protection against ingress of dust, dirt, and moisture. This design helps maintain internal lubrication, reduces maintenance needs, and extends service life in challenging conditions.
Built to the standard 69 series, the 6906-2RS offers substantial radial load capacity within a relatively slim profile. Its deep groove geometry also accommodates moderate axial loads from either direction, supporting stable operation in varied load scenarios.
Precision-ground components and optimized internal geometry ensure low vibration and consistent performance. The sealed construction minimizes the frequency of re-lubrication, making it a reliable, low-maintenance solution for enclosed assemblies.
