3206 ATN9 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness and enables handling of substantial combined loads (6862 lbf dynamic, 4950 lbf static ratings). The optimized contact angle ensures efficient distribution of both radial and axial forces.
High-Speed Performance: The TN9 nylon cage reduces friction and enables operation at limiting speeds up to 10,000 rpm, making it an ideal high-speed bearing solution.
Precision Engineering: Manufactured to P6 tolerance class with precise bearing dimensions (bore tolerance: -0.008mm to 0) ensures consistent performance in precision applications.
Material Excellence: Chrome steel rings and balls provide exceptional durability and wear resistance, while the lightweight nylon cage contributes to reduced vibration and noise.
