4205 ATN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness and stability, making it ideal for applications requiring precise shaft positioning and minimal deflection under load.
Enhanced Load Capacity: With a radial dynamic load rating of 4275 lbf and radial static load rating of 3285 lbf, this bearing effectively handles combined loads while maintaining operational reliability.
Optimized High-Speed Performance: The TN9 nylon cage reduces centrifugal forces and friction, supporting a limiting speed of 20,000 rpm while the CN radial clearance ensures optimal performance across various operating conditions.
Maintenance-Free Operation: The integrated Soild Oil lubrication (W64) provides consistent lubrication throughout the bearing's service life, eliminating the need for relubrication and reducing maintenance costs.
