1206KTNC3 Bearing Product Overview & Core Advantages
The 1206KTNC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. Featuring a tapered bore (1:12) and C3 radial internal clearance, this bearing excels at handling combined loads while maintaining dimensional stability. Its nylon cage construction enables smooth operation at limiting speeds up to 15,000 rpm, making it ideal for demanding industrial environments where reliability and performance are critical.
1206KTNC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1206 | Standard bore diameter 30mm, outside diameter 62mm | Compact bearing dimensions for space-constrained applications |
| KTN | Tapered bore 1:12 with nylon cage | Enhanced mounting precision and high-speed capability |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion in high-temperature operations |
1206KTNC3 Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row construction provides superior stiffness compared to single row bearings, enabling precise shaft positioning and reduced deflection under combined radial and axial loads.
Optimized Load Capacity: With a dynamic load rating of 3510 lbf and static load rating of 1046 lbf, this bearing delivers reliable performance in applications experiencing significant stress and vibration.
Enhanced Speed Performance: The nylon cage material reduces friction and enables operation at limiting speeds of 15,000 rpm, while the tapered bore ensures secure mounting for high-speed applications.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.01mm to 0), this precision bearing maintains consistent performance in demanding operating conditions.
1206KTNC3 Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers requiring rigid support and thermal stability
