1205 EKTN9/C3W64 Bearing Product Overview & Core Advantages
The 1205 EKTN9/C3W64 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision performance. Featuring a tapered bore (1:12) and C3 radial internal clearance, this metric bearing delivers exceptional stability under combined loads while maintaining precise dimensional tolerances. Its optimized bearing dimensions (25mm bore × 52mm OD × 15mm width) provide compact yet robust solutions for demanding industrial environments.
1205 EKTN9/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
| EK | Optimized internal design | Enhanced load capacity and stress distribution |
| TN9 | Nylon cage, glass fiber reinforced | Reduced friction, suitable for high-speed applications |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature operations |
| W64 | Special lubrication specification | Extended service life across temperature range (-30° to 110°C) |
1205 EKTN9/C3W64 Bearing Structural Features & Performance Benefits
Double Row Design: The double row ball bearing configuration provides superior high rigidity and moment load capacity compared to single row designs, making it ideal for applications with significant radial and axial load combinations.
Precision Tapered Bore: The 1:12 taper enables precise mounting on tapered shafts, ensuring secure fit and optimal load distribution. Combined with tight dimensional tolerances (bore: -0.01mm to 0), this feature guarantees precision bearing performance.
Advanced Cage Technology: The TN9 nylon cage with glass fiber reinforcement contributes to the bearing's high-speed capability (limiting speed: 18,000 rpm) by reducing centrifugal forces and maintaining proper ball guidance.
Optimized Internal Clearance: The C3 radial internal clearance accommodates thermal expansion in high-speed or high-temperature applications, preventing premature failure due to excessive preload.
