The NP428874/NP108329 RICH is a high-precision single row tapered roller bearing engineered to support heavy combined radial and axial loads. With inch-based dimensions of 30.162 mm bore, 64.292 mm outer diameter, and 19.05 mm total width, this bearing is designed for demanding automotive and industrial power transmission systems requiring strict dimensional accuracy.

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

Manufactured to provide reliable long-term performance, the NP428874/NP108329 RICH is built to withstand the rigorous stresses of high-torque environments. Its robust construction ensures stability and high resistance to wear, making it a dependable choice for precision-critical assemblies.

Key Performance Advantages:

• High Load Capacity: Designed to manage simultaneous radial and thrust loads in one direction effectively.
• Separable Construction: Facilitates easier mounting, inspection, and maintenance of axle and gearbox units.
• Precision Roller Geometry: Ensures smooth rotation, reduced friction, and enhanced bearing life.
• Dimensional Consistency: Suitable for standard NP-series tapered bearing applications requiring inch-series precision.
• RICH Engineering Quality: Built to meet rigorous dimensional and functional tolerances for the automotive aftermarket.

Typical Applications:

• Automotive axles and differential assemblies.
• Manual and automatic transmission systems.
• Industrial gearboxes and powertrain components.
• Heavy-duty machinery requiring high radial and axial load support.
