1205KTN Bearing Product Overview & Core Advantages
The 1205KTN is a metric double row angular contact ball bearing designed for applications requiring high precision and reliable performance. This bearing features a tapered bore (1:12) that enables precise interference fit adjustments for optimal internal clearance control. Its double row construction provides superior rigidity and the ability to handle combined loads - both radial and axial forces simultaneously. The nylon cage ensures smooth operation at high speeds while maintaining excellent dimensional stability across the operating temperature range.
1205KTN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 1205 | Standard bore diameter (25mm) and series designation | Standardized dimensions for easy replacement and interchangeability |
| K | Tapered bore with 1:12 ratio | Enables precise clearance adjustment through mounting position |
| TN | Nylon cage (injection molded) | Reduced friction, excellent high-speed performance, and quiet operation |
1205KTN Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row angular contact configuration provides significantly increased stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under load.
Superior Load Capacity: Engineered to handle combined radial and axial loads simultaneously, with a dynamic load rating of 3218 lbf and static load rating of 900 lbf. The optimized contact angle distribution ensures balanced load sharing between both rows.
High-Speed Performance: The nylon TN cage combined with factory lubrication enables operation at limiting speeds up to 18,000 rpm. The lightweight cage material reduces centrifugal forces and maintains stability at elevated rotational speeds.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.01mm to 0, OD: -0.013mm to 0) and CN radial internal clearance for consistent performance in precision applications.
