1209TN Bearing Product Overview & Core Advantages
The 1209TN is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric bearing features an open design and is capable of accommodating combined loads, including significant radial loads and moderate axial loads in both directions. Its compact double row construction provides enhanced stiffness and rotational accuracy, making it ideal for high-performance machinery where space constraints and reliable operation are critical. The bearing comes pre-lubricated and features a nylon cage for smooth, high-speed operation.
1209TN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1209 | Basic bearing designation: 45 mm bore, 85 mm OD, 19 mm width |
| TN | Nylon (polyamide) cage, molded type. Enables higher limiting speeds and reduced friction. |
1209TN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides superior radial stiffness and can support combined radial and axial loads simultaneously. With a dynamic load rating of 5152 lbf and static load rating of 1755 lbf, it ensures reliable performance under demanding conditions.
- High-Speed Performance: The lightweight TN nylon cage reduces centrifugal forces, contributing to a high limiting speed of 11,000 rpm. This makes it suitable for high-speed applications.
- Precision & Stability: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.012mm to 0, OD: -0.015mm to 0) and standard CN radial internal clearance, ensuring smooth operation and precise positioning.
- Maintenance-Friendly: Pre-lubricated for immediate use and features an open seal type, allowing for re-lubrication if required in specific applications.
1209TN Bearing Typical Application Areas
The 1209TN double row angular contact ball bearing is widely used in various industrial sectors due to its robust design and high performance. Key applications include:
- Electric Motors & Generators
- Gearboxes & Transmission Systems
- Industrial Pumps & Compressors
