1210 EKTN9/W64 Bearing Product Overview & Core Advantages
The 1210 EKTN9/W64 is a metric double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore (1:12) and is pre-lubricated for immediate use. Its double row design provides high rigidity and the ability to support significant combined loads, including radial and bidirectional axial loads, making it ideal for high-reliability scenarios where compact design and robust performance are critical.
1210 EKTN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| EK | Optimized internal design | Enhanced load capacity and performance. |
| TN9 | Nylon (Polyamide) cage, glass fiber reinforced | Reduced friction, suitable for high-speed operation and offering good guiding properties. |
| W64 | Bearing is filled with a special lubricant | Provides long-term lubrication, reducing maintenance needs and ensuring consistent performance. |
1210 EKTN9/W64 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact ball bearing construction provides superior stiffness, enabling stable operation under heavy combined loads and moment loads. The optimized internal geometry maximizes the radial dynamic load rating of 5962 lbf.
- High-Speed Performance: The lightweight TN9 nylon cage minimizes centrifugal forces, contributing to a high limiting speed of 10,000 rpm. The open design facilitates efficient lubrication distribution.
- Pre-lubricated & Ready-to-Use: Filled with a special lubricant (W64), the bearing is prepped for operation, offering a wide temperature range from -30°C to 110°C and reducing initial setup time.
- Precision Tapered Bore: The 1:12 taper allows for precise interference fit on adapter sleeves or tapered shafts, ensuring secure mounting and eliminating internal clearance for maximum running accuracy.
1210 EKTN9/W64 Bearing Typical Application Areas
This versatile double row angular contact ball bearing is engineered for high-performance machinery, including:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
