The 45282/45220 RICH is a high-performance single row tapered roller bearing specifically engineered to handle extreme combined radial and axial loads. With inch-series dimensions of 47.625 mm bore, 104.775 mm outer diameter, and 30.162 mm total width, this bearing is a robust solution for heavy-duty industrial and automotive applications where maximum structural integrity and load-carrying capacity are required.

The internal geometry features tapered rollers and raceways arranged to ensure that resultant loads are distributed uniformly across the contact surfaces. This design significantly reduces frictional torque and heat generation, even under high-torque conditions. The steel cage provides precise roller guidance and high durability, ensuring stable and reliable rotation throughout the bearing's service life.

As a separable bearing, the cone (inner ring assembly) and the cup (outer ring) can be mounted independently. This allows for precise adjustment of internal clearance or preload during installation, a critical factor for optimizing the performance of heavy machinery axles, differential units, and industrial gearboxes.

Key Performance Advantages:

• Extra-Heavy Load Capacity: Optimized to manage massive simultaneous radial and thrust forces.
• Durable Steel Cage: High-strength construction ensures stability in demanding mechanical environments.
• Separable Construction: Facilitates easier mounting, simplified maintenance, and precision system adjustment.
• High Structural Rigidity: Engineered with premium-grade steel to resist deformation under extreme operational stress.
• RICH Engineering Standard: Manufactured to exacting tolerances for a perfect aftermarket fit in standardized inch-series assemblies.

Typical Applications:

• Heavy-duty vehicle transmissions and differential assemblies.
• Industrial gear reducers and primary drive units.
• Agricultural machinery axle systems and high-torque final drives.
• Mining and construction equipment subjected to extreme radial and axial stress.
