The NP868033/NP666556 RICH is a high-precision single row tapered roller bearing engineered to support heavy combined radial and axial loads. With dimensions of 25 mm bore, 66 mm outer diameter, and 22 mm total width, this bearing is designed for superior performance in demanding automotive and industrial power transmission systems where space is optimized for high load density.

The tapered roller geometry ensures uniform load distribution across the raceways, reducing friction and improving rotational efficiency. The separable design — consisting of cone (inner ring with roller assembly) and cup (outer ring) — allows for independent installation and precise adjustment of internal clearance or preload during assembly. This feature is critical for maintaining the operational integrity and longevity of high-torque drivetrain components.

Manufactured to rigorous standards, the NP868033/NP666556 RICH provides reliable long-term performance. Its robust construction ensures stability and high resistance to wear, even under the most challenging operational conditions found in modern mechanical assemblies.

Key Performance Advantages:

• High Load Capacity: Specifically optimized to manage simultaneous radial and thrust loads in one direction.
• Separable Construction: Facilitates easier mounting, precise adjustment, and simplified maintenance.
• Precision Roller Geometry: Ensures smooth rotation, reduced heat generation, and an extended bearing life.
• Structural Rigidity: Engineered for maximum stability in high-torque industrial and automotive environments.
• RICH Engineering Quality: Built to meet exacting dimensional and functional tolerances for the aftermarket.

Typical Applications:

• Automotive differential assemblies and transmission systems.
• Industrial gearboxes and speed reducers.
• Axle and hub assemblies for light and medium-duty vehicles.
• Power transmission components in agricultural and construction machinery.
