1222S Bearing Product Overview & Core Advantages
The 1222S is a double row angular contact ball bearing designed for applications requiring high radial load capacity and precision performance. This metric bearing features an open design without seals, allowing for optimal lubrication access and heat dissipation. Its double row construction provides superior rigidity and stability, making it ideal for machinery subjected to significant radial forces. Manufactured from chrome steel with a stainless steel cage, it delivers excellent durability and consistent operation in demanding industrial environments.
1222S Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1222 | Standard bearing designation indicating bore diameter (110mm), outside diameter (200mm), and width (38mm) |
| S | Indicates special internal clearance and dimensional tolerances for precision applications |
1222S Bearing Structural Features & Performance Benefits
High Rigidity Design: The double row ball bearing configuration provides enhanced stiffness, reducing deflection under heavy radial loads and ensuring precise shaft positioning.
Superior Load Capacity: With a dynamic load rating of 19,890 lbf and static load rating of 8,775 lbf, this bearing handles substantial radial forces while maintaining operational stability.
Optimized High-Speed Performance: The stainless steel cage and precision-ground components enable reliable operation at limiting speeds up to 4,300 rpm, making it suitable for high-speed applications.
Precision Engineering: Manufactured with tight dimensional tolerances (bore: -0.02mm to 0, outside diameter: -0.03mm to 0) and CN radial internal clearance for consistent performance in precision machinery.
Wide Temperature Range: Operates effectively in temperatures from -30°C to 110°C, accommodating various industrial environments and operating conditions.
