1222-M Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior radial stiffness, enabling effective support for heavy radial loads. With a dynamic load rating of 19,890 lbf and static load rating of 8,775 lbf, this bearing excels in applications requiring substantial load-bearing capability.
Optimized Speed Performance: The brass cage (M designation) ensures stable operation at speeds up to 4,300 rpm, making it suitable for various industrial applications. The CN radial internal clearance provides optimal performance under normal operating conditions.
Precision Engineering: Manufactured from chrome steel for both rings and balls, this bearing offers excellent wear resistance and durability. The precise dimensional tolerances (bore: -0.02mm to 0, outside diameter: -0.03mm to 0) ensure consistent performance and easy installation.
1222-M Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Material Handling Equipment including conveyor systems
- Agricultural Machinery requiring robust bearing solutions
- Industrial Fans and blowers operating at moderate speeds
- General Industrial Machinery where high radial load capacity is essential
