1200 Bearing Product Overview & Core Advantages
The 1200 series double row angular contact ball bearing represents a precision bearing solution engineered for applications requiring high rigidity and compact design. This metric bearing features an open construction and is pre-lubricated for immediate operation. Its fundamental advantage lies in its ability to support substantial combined loads, handling both radial forces and bidirectional axial loads simultaneously. Manufactured with chrome steel rings and balls, and featuring a lightweight nylon cage, it is designed for high-speed operation and reliable performance in demanding environments, making it an ideal choice for high-reliability applications.
1200 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1200 | Basic series designation for a double row angular contact ball bearing. |
| Open | Bearing construction without seals or shields, allowing for higher speeds and different lubrication methods. |
| CN | Specifies the standard radial internal clearance group for normal operating conditions. |
1200 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized contact angle provide superior high rigidity, enabling the bearing to withstand significant combined loads (radial and bidirectional axial).
- High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 36,000 rpm. The open design further facilitates efficient lubrication and heat dissipation.
- Precision & Durability: Components made from chrome steel offer high wear resistance and durability. The precise bearing dimensions (10mm bore, 30mm OD, 9mm width) and tight tolerances ensure consistent performance and ease of integration.
- Ready-to-Use: The bearing comes lubricated from the factory, simplifying installation and providing immediate protection during the initial run-in period.
