The 25880R/25820 RICH is a high-precision single row tapered roller bearing engineered to support significant combined radial and axial loads. With inch-series dimensions of 36.487 mm bore, 73.025 mm outer diameter, and 23.812 mm total width, this bearing is designed for superior performance in automotive and industrial driveline systems where high structural stiffness and rotational accuracy are essential.

The tapered roller geometry ensures uniform load distribution across the contact surfaces, effectively reducing friction and heat generation during high-torque operation. The separable design — consisting of the cone (inner ring assembly) and the cup (outer ring) — allows for independent installation. This feature facilitates the precise adjustment of internal clearance or preload during assembly, which is critical for maintaining the operational integrity and longevity of high-torque axles and gearboxes.

Built with high-grade steel and manufactured to meet rigorous dimensional and functional tolerances, the 25880R/25820 RICH provides reliable long-term performance. Its robust construction ensures stability and high resistance to wear, making it a dependable choice for demanding mechanical environments where vibration-free rotation is required.

Key Performance Advantages:

• High Combined Load Capacity: Optimized to manage simultaneous radial and thrust loads in a single direction.
• Separable Construction: Facilitates easier mounting, inspection, and maintenance of transmission and axle units.
• Precision Roller Geometry: Ensures smooth rotation, reduced frictional torque, and enhanced bearing life.
• Dimensional Stability: Manufactured to resist deformation under heavy operational stress in industrial applications.
• RICH Engineering Standard: Built to exacting tolerances for a perfect aftermarket fit in standardized inch-series assemblies.

Typical Applications:

• Automotive differential assemblies and heavy-duty transmissions.
• Industrial gear reducers and motorized pulleys.
• Vehicle wheel hubs and axle support systems for commercial transport.
• Agricultural machinery powertrain components subjected to high axial thrust.
