1206 EKTN9/C3W64 Bearing Product Overview & Core Advantages
The 1206 EKTN9/C3W64 is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precision performance. Featuring a unique tapered bore (1:12) design, this bearing delivers exceptional stability under combined radial and axial loads. Its optimized internal geometry and C3 radial internal clearance make it particularly suitable for high-precision machinery where rigid support and reliable operation are critical. The nylon cage construction contributes to smooth operation at elevated speeds.
1206 EKTN9/C3W64 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |

1206 EKTN9/C3W64 Bearing Structural Features & Performance Benefits
Double Row Design: The double row angular contact configuration provides significantly increased rigidity and load capacity compared to single row bearings, making it ideal for applications with substantial combined loads.
Tapered Bore Technology: The 1:12 tapered bore enables precise interference fit mounting, ensuring maximum shaft contact and eliminating internal clearance for superior running accuracy.
High-Speed Capability: The TN9 nylon cage minimizes centrifugal forces and reduces friction, enabling operation at limiting speeds up to 15,000 rpm while maintaining stability.
Optimized Internal Clearance: The C3 radial clearance provides adequate space for thermal expansion during high-speed operation, preventing premature failure due to excessive preload.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, ensuring excellent wear resistance and durability under demanding operating conditions.
