1211KTN Bearing Product Overview & Core Advantages
The 1211KTN is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Featuring a tapered bore (1:12 ratio), this precision bearing offers excellent running accuracy and is pre-lubricated for immediate use. Its compact design and high load capacity make it ideal for demanding industrial environments where space constraints and performance are critical factors.
1211KTN Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1211 | Standard bearing series designation with 55mm bore and 100mm OD |
| K | Tapered bore with 1:12 ratio for precise mounting on adapter sleeves |
| TN | Nylon cage (polyamide) for reduced weight and smooth operation at high speeds |
1211KTN Bearing Structural Features & Performance Benefits
Double Row Design: Provides high rigidity and enhanced load carrying capacity compared to single row bearings, effectively handling combined radial and axial loads in both directions.
Tapered Bore: Enables precise axial positioning and secure mounting on adapter sleeves, ensuring optimal performance and simplified installation.
Nylon Cage (TN): Contributes to high-speed capability with lower friction, reduced vibration, and excellent acceleration characteristics.
Pre-lubricated: Factory-applied lubrication ensures immediate operation and reduced maintenance requirements across the operating temperature range of -30°C to 110°C.
Precision Tolerances: Tight dimensional tolerances on bore, outside diameter, and width ensure consistent performance and precise bearing fit in applications.
