1209 ETN9 Bearing Product Overview & Core Advantages
The 1209 ETN9 is a metric double row angular contact ball bearing engineered for high-performance applications requiring exceptional rigidity and radial load capacity. Its compact design, featuring a 45 mm bore and 85 mm outside diameter, delivers robust support in a space-efficient package. Manufactured from high-grade chrome steel and equipped with a nylon cage (TN9), this bearing is optimized for high-speed operation up to 11,000 rpm. It comes pre-lubricated for immediate use and is designed to handle demanding conditions with reliability.

| Code Segment | Technical Meaning |
| 1209 | Standard bearing series designation indicating metric dimensions (45mm bore × 85mm OD × 19mm width) |
| E | Optimized internal design for enhanced load capacity and performance |
| TN9 | Nylon cage providing excellent high-speed capability, low friction, and reduced weight |
1209 ETN9 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior radial stiffness and enables the bearing to support significant radial loads (dynamic: 5152 lbf / static: 1755 lbf), making it ideal for applications with substantial forces.
- Optimized High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces and ensures stable operation at the maximum limiting speed of 11,000 rpm.
- Precision & Durability: Components made from chrome steel offer high wear resistance and dimensional stability, supported by tight tolerances for precise mounting and alignment.
- Ready-to-Use Convenience: The bearing is pre-lubricated and features an open design, facilitating easy re-lubrication in service for extended operational life within a temperature range of -30°C to 110°C.
1209 ETN9 Bearing Typical Application Areas
This bearing is widely used in industrial machinery where high radial load capacity and speed are critical. Common applications include:
- Industrial gearboxes and transmission systems
- Electric motor shafts and spindles
- Material handling equipment
- Pumps and compressors
- Agricultural machinery
