7006 CE/DTVQ126 Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The duplex tandem arrangement with factory-set preload provides exceptional system stiffness, minimizing deflection under load. Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, this bearing ensures precise shaft positioning and smooth operation.
Optimized High-Speed Performance: Featuring a phenolic resin cage and 15° contact angle, the 7006 CE/DTVQ126 achieves a remarkable limiting speed of 100,500 rpm. The cage design reduces centrifugal forces and friction, while the optimized internal geometry minimizes heat generation at high rotational speeds.
Superior Load Capacity: With a radial dynamic load rating of 3,398 lbf and radial static load rating of 2,340 lbf, this bearing efficiently handles combined radial and axial loads. The tandem arrangement specifically enhances axial load capacity in one direction, making it suitable for applications with significant thrust requirements.
Premium Material Construction: Manufactured from chrome steel for both rings and balls (6.35 mm diameter, 17 balls), this bearing offers excellent wear resistance and durability across the operating temperature range of -30°C to 110°C.
