1309 ETN9/C3 Bearing Structural Features & Performance Benefits
Double Row Design: The two-row ball arrangement provides high rigidity and superior stability under radial loads, making it ideal for applications requiring precise shaft positioning.
Optimized Internal Geometry: The E-design internal structure enhances load distribution, enabling the bearing to handle combined loads effectively while maintaining operational precision.
Nylon Cage (TN9): The glass fiber reinforced nylon cage contributes to high-speed capability with a limiting speed of 8,500 rpm, while providing excellent wear resistance and reduced vibration.
C3 Radial Clearance: This increased internal clearance accommodates thermal expansion differences between bearing components, ensuring reliable performance across the operating temperature range of -30°C to 110°C.
Chrome Steel Construction: Both rings and balls are manufactured from high-quality chrome steel, providing excellent durability and fatigue resistance under demanding conditions.
