1211 P/6 Bearing Product Overview & Core Advantages
The 1211 P/6 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling combined loads, including significant radial loads and bidirectional axial loads. Its compact bearing dimensions (55mm bore, 100mm OD, 21mm width) and robust construction deliver high rigidity and operational stability, making it an ideal choice for high-reliability machinery requiring precise shaft guidance and minimal deflection.
1211 P/6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1211 | Standard bearing series designation, indicating the basic size (55mm bore). |
| P | Indicates a glass fiber reinforced polyamide (Nylon) cage, offering low weight, quiet operation, and excellent performance at high speeds. |
| 6 | Specifies a CN radial internal clearance, which is the standard (normal) clearance group for general applications. |
1211 P/6 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness compared to single row bearings, effectively supporting combined loads from multiple directions and minimizing shaft runout.
- Optimized for High-Speed Operation: The lightweight and robust Nylon cage (P) ensures stable ball guidance, reduces centrifugal forces, and contributes to the high limiting speed of 9,000 rpm, qualifying it as a high-speed bearing.
- Precision & Durability: Manufactured from high-grade Chrome Steel for both rings and balls, this bearing ensures long service life and consistent performance under dynamic loads (Radial dynamic load rating: 6210 lbf).
- Ready-to-Use: The bearing comes lubricated from the factory, facilitating easy installation and immediate operation within its specified temperature range of -30°C to 110°C.
