1308 ETN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides exceptional stiffness and enables the bearing to handle substantial combined loads (7605 lbf dynamic, 2520 lbf static ratings). This construction ensures stable operation under complex loading conditions.
High-Speed Performance: The TN9 nylon cage offers excellent strength-to-weight ratio, contributing to the bearing's impressive limiting speed of 9,500 rpm. The cage's design minimizes friction and allows for smooth operation at high rotational speeds.
Precision Engineering: Manufactured with chrome steel rings and balls, the bearing maintains dimensional stability and provides consistent performance. The CN radial internal clearance ensures optimal operation for most industrial applications.
Temperature Resilience: With an operating temperature range of -30°C to 110°C and specialized lubrication, the bearing maintains reliable performance in varied environmental conditions.
