11209 Bearing Product Overview & Core Advantages
The 11209 metric ball bearing is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. Its double row construction provides exceptional stability, enabling it to handle significant radial loads while also accommodating axial loads from both directions. Manufactured with precision components including a nylon cage, this bearing is optimized for smooth operation and is pre-lubricated for immediate use, making it an ideal choice for high-reliability industrial applications.
11209 Bearing Model Code Explained, Specifications & Naming Convention
While the base designation "11209" defines the core dimensions, this bearing features specific design and material attributes that define its performance:
- 11209: Standard designation for a double row angular contact ball bearing with a 45mm bore, 85mm OD, and 58mm width.
- Open (Seal Type): The bearing is supplied without contact seals, allowing for higher limiting speeds and easier re-lubrication.
- Cage Material: Nylon: The use of a lightweight polymer cage reduces centrifugal forces, contributing to lower operating temperatures and a higher limiting speed.
- Lubricated: The bearing is pre-lubricated with a high-quality grease suitable for the specified temperature range.
- Radial Internal Clearance: CN: Denotes standard (normal) internal clearance, which is suitable for a wide range of common operating conditions.
11209 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a significantly wider load-carrying surface compared to single row bearings, resulting in superior rigidity and the ability to support substantial radial dynamic load ratings (5152 lbf) and static load ratings (1755 lbf). This makes it exceptionally resistant to deflection under combined loads.
- Optimized High-Speed Performance: The lightweight nylon cage is a key factor in achieving the high limiting speed of 4,500 rpm. It ensures stable ball guidance with minimal friction and is well-suited for rapid acceleration and deceleration cycles.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and long service life. The precise bearing dimensions and tight tolerances ensure consistent performance and ease of installation.
11209 Bearing Typical Application Areas
This versatile double row angular contact ball bearing is engineered for demanding environments across various industries, including:
- Industrial Gearboxes and Transmissions
- Medium-Duty Pump and Compressor Systems
- Material Handling Equipment
- Agricultural Machinery
- General Industrial Machinery requiring robust, high-capacity rotary support.
