306493 AA Bearing Structural Features & Performance Benefits
- High Load Capacity: The single row deep groove design is optimized to support high radial loads, with a dynamic rating of 233,801 lbf and a substantial static rating of 606,984 lbf, ensuring longevity under heavy-duty conditions.
- Robust Construction: Components made from chrome steel (rings, balls) provide high hardness and wear resistance. The stainless steel cage offers superior strength and corrosion resistance, contributing to the bearing's overall reliability.
- Precision and Stability: Manufactured to P0 tolerance class and standard CN radial internal clearance, this bearing ensures consistent performance and smooth operation. The locating slot on the outer ring facilitates secure mounting and alignment.
- Application-Specific Design: As an open bearing without seals, it is intended for applications where the bearing is integrated into a sealed housing or will be lubricated by the host system. The specified limiting speed is 0.5 x 1000 rpm.
306493 AA Bearing Typical Application Areas
This large-bore, high-capacity bearing is suited for heavy industrial machinery, including:
- Large-Diameter Gearboxes and Drives
- Heavy-Duty Conveyor Systems
- Industrial Fans and Blowers
- Mining and Construction Equipment
- Paper Mill Machinery
- Vibrating Screens and other processing equipment
