1309 EKTN/SNW 109X1.1/2 Bearing Product Overview & Core Advantages
The 1309 EKTN/SNW 109X1.1/2 is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and precision. Its double row design provides superior stiffness and enables it to accommodate combined loads (radial and axial loads simultaneously). Featuring an open design and a tapered bore (1:12), it is optimized for precise mounting on adapter sleeves or withdrawal sleeves. Constructed from chrome steel with a nylon cage, this bearing offers excellent performance in high-speed applications, with a limiting speed of 8,500 rpm, making it a reliable choice for demanding industrial environments.
1309 EKTN/SNW 109X1.1/2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1309 E | Basic bearing designation with optimized internal design. |
| K | Indicates a tapered bore (1:12 ratio). |
| TN9 | Signifies a glass fiber reinforced nylon cage, contributing to low weight, quiet operation, and suitability for high speeds. |
| /SNW | Refers to the specific adapter sleeve designation required for mounting. |
| 109X1.1/2 | Specifies the adapter sleeve size for a shaft diameter of 1-1/2 inches. |
1309 EKTN/SNW 109X1.1/2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact construction provides significantly greater rigidity compared to single row bearings, allowing it to handle substantial radial loads and moderate axial loads in both directions.
- Optimized for High Speeds: The lightweight TN9 nylon cage reduces centrifugal forces, lowers operating temperatures, and enables a high limiting speed of 8,500 rpm.
- Tapered Bore for Secure Mounting: The 1:12 tapered bore allows for precise and secure mounting on an adapter sleeve, ensuring a tight fit on the shaft and simplifying installation and removal.
- Precision & Durability: Manufactured from high-grade chrome steel for both rings and balls, this bearing ensures long service life and consistent performance under demanding conditions. The standard CN radial internal clearance is suitable for most common operating conditions.
1309 EKTN/SNW 109X1.1/2 Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery requiring high precision and reliability, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Fans
- Material Handling Equipment
- Agricultural Machinery
- Machinery utilizing adapter sleeves for mounting on standard shaft sizes.
