S7007 ACE/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design and 25° contact angle provide superior stiffness and enable the bearing to handle significant combined radial and axial loads from both directions, making it ideal for complex loading conditions.
High-Speed Performance: The lightweight phenolic cage is instrumental in achieving a high limiting speed of 41,000 rpm. This material offers excellent strength-to-weight ratio and operates smoothly at high rotational velocities.
Precision & Longevity: Manufactured to a P4A tolerance class, this bearing ensures minimal runout and vibration. The sealed construction and factory-applied grease lubrication protect against contamination and provide a long service life within the specified temperature range of -30°C to 110°C, reducing maintenance needs.
