The 3382/3320 RICH is a high-precision single row tapered roller bearing engineered to support substantial combined radial and axial loads. With inch-series dimensions of 39.688 mm bore, 80.167 mm outer diameter, and 29.37 mm total width, this bearing is designed for superior durability in agricultural and industrial powertrain systems requiring high structural rigidity.

The internal geometry features tapered rollers and raceways arranged to ensure that resultant loads are distributed uniformly across the contact surfaces, significantly reducing frictional torque and heat generation. The separable design — consisting of the cone (inner ring assembly) and the cup (outer ring) — allows for independent installation and facilitates the precise adjustment of internal clearance or preload. This adjustability is fundamental for maintaining the operational integrity of high-torque axles and gearboxes.

Built with high-grade steel and manufactured to meet rigorous dimensional tolerances, the 3382/3320 RICH provides reliable long-term performance. It serves as a direct, high-quality replacement for specialized components like the Massey Ferguson 203828M11, ensuring stable and vibration-free rotation in demanding field conditions.

Key Performance Advantages:

• High Combined Load Capacity: Specifically optimized to manage simultaneous radial and thrust loads in one direction.
• Separable Construction: Simplifies mounting, inspection, and maintenance procedures in complex mechanical housings.
• Precision Roller Engineering: Minimizes friction and enhances overall energy efficiency in the driveline.
• Direct OE Compatibility: Engineered to match the exact functional standards of Massey Ferguson agricultural equipment.
• RICH Engineering Standard: Manufactured to provide a perfect aftermarket fit for standardized inch-series tapered applications.

Typical Applications:

• Agricultural machinery (Tractors, harvesters, and Massey Ferguson drivetrain units).
• Industrial gear reducers and high-torque speed converters.
• Heavy-duty vehicle wheel hubs and differential systems.
• Construction equipment requiring robust axial and radial support.
