2200 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle significant combined loads without compromising performance. This construction ensures stable operation even under varying load conditions.
High-Speed Performance: The TN9 nylon cage contributes to the bearing's excellent high-speed characteristics by reducing centrifugal forces and maintaining ball guidance at elevated rotational speeds up to 34,000 rpm.
Maintenance Efficiency: As an open bearing pre-lubricated with W64 grease, it offers reliable operation across a broad temperature range (-30°C to 110°C) while minimizing the need for relubrication during service.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances, this bearing ensures consistent performance and long service life in precision applications.
