1211J Bearing Product Overview & Core Advantages
The 1211J metric ball bearing is a double row angular contact ball bearing engineered for applications requiring robust support for radial loads. Its double row design provides enhanced rigidity and load-carrying capacity within a compact cross-section. Manufactured from high-grade chrome steel for both rings and balls, this bearing offers reliable performance and long service life. It is pre-lubricated, simplifying installation and is suitable for a wide operating temperature range, making it a versatile and high-value component for various industrial applications.
1211J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1211 | Standard bearing designation indicating a metric double row bearing with a 55 mm bore diameter and 100 mm outside diameter. |
| J | Suffix denoting a CN group radial internal clearance as standard, which is the normal clearance range for general applications. |
1211J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction provides superior radial stiffness compared to single row bearings, enabling it to handle higher radial dynamic load ratings (6210 lbf) effectively.
- Optimized Internal Geometry: Precision-ground raceways and balls ensure smooth operation and contribute to the bearing's limiting speed of 9,000 rpm.
- Robust Cage Design: The pressed steel cage ensures secure ball guidance and is suitable for high-speed operation, contributing to the bearing's overall durability.
- Pre-lubricated & Ready-to-Use: The bearing comes lubricated from the factory, reducing initial setup time and ensuring immediate operational readiness.
- Material Integrity: Constructed entirely from chrome steel, the bearing offers excellent resistance to wear and fatigue, ensuring a long operational lifespan.
1211J Bearing Typical Application Areas
This double row ball bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Industrial gearboxes and transmission systems
- Electric motors and generators
- Material handling equipment (conveyors, pulleys)
- Agricultural machinery
- General industrial machinery requiring robust radial load support
