The 45285A/45221 RICH is a heavy-duty single row tapered roller bearing engineered for robust performance and exceptional reliability under significant combined radial and axial loads acting in a single direction. The tapered geometry of the rolling elements and raceways ensures true rolling motion and efficient load distribution. With large dimensions of 50.8 mm bore, 104.775 mm outer diameter, and a 30.162 mm total width (T), this bearing is crucial for high-stress applications in industrial machinery, commercial vehicles, and gear reduction units. The bearing is characterized by its separable design, where the cone (inner ring assembly, 45285A) and the cup (outer ring, 45221) can be mounted independently. This feature greatly aids in simplifying assembly and allowing for precise adjustment of the bearing clearance.
Key Performance Advantages:
- Heavy Load Capacity: Optimized to withstand demanding simultaneous radial forces and high single-direction axial forces.
- Separable Design: Cone and cup can be fitted separately, streamlining installation and allowing for precise axial setting.
- Durability: Robust construction ensures reliable operation and long service life in challenging environments.
- RICH Quality: A high-capacity component built for accuracy and resilience in large-scale mechanical systems.
