1212 EKTN9/W64 Bearing Product Overview & Core Advantages
The 1212 EKTN9/W64 is a double row angular contact ball bearing designed for applications requiring high precision and reliability. Featuring a tapered bore (1:12) and open construction, this precision bearing delivers exceptional high rigidity and can accommodate combined loads including significant radial forces. Its compact design with optimized bearing dimensions (60mm bore, 110mm OD, 22mm width) makes it ideal for space-constrained, high-performance applications.
1212 EKTN9/W64 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| EK | Optimized internal design with increased load capacity |
| TN9 | Nylon cage, polymer material for reduced weight and superior high-speed performance |
| W64 | Special lubrication for extended service life and optimal temperature range (-30° to 110°C) |
1212 EKTN9/W64 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial stiffness, enabling the bearing to handle combined loads effectively while maintaining precision alignment. With a dynamic load rating of 7020 lbf and static load rating of 2745 lbf, it offers reliable performance under demanding conditions.
High-Speed Performance: The TN9 nylon cage reduces rotational mass and friction, contributing to excellent high-speed capability with a limiting speed of 8000 rpm. The optimized internal geometry further enhances operational stability at elevated speeds.
Precision & Longevity: Manufactured from chrome steel with CN radial internal clearance, this bearing ensures consistent precision. The pre-lubricated design with W64 special grease provides maintenance-free operation throughout the specified temperature range.
