The HM801346X/801310 RICH is a high-precision single row tapered roller bearing engineered for heavy-duty applications requiring high radial and axial load capacity. With its inch-series dimensions of 38.1 mm bore and 82.55 mm outer diameter, this bearing is a robust solution for power transmission assemblies where structural stiffness and durability are critical.

The design of the HM (Heavy Medium) series ensures that the bearing can handle significant combined loads by distributing stress evenly across the tapered rollers and raceways. The separable nature of the cone (inner ring assembly) and cup (outer ring) allows for independent mounting and facilitates precise adjustment of internal clearance or preload during installation, which is essential for optimizing the performance of high-torque gearboxes and axles.

Manufactured with high-grade steel to resist fatigue and wear, the HM801346X/801310 RICH ensures reliable rotation and a long service life in challenging industrial and automotive environments. The specific rounding radii (R1/R2) are optimized to ensure a perfect fit on stepped shafts and within housings.

Key Performance Advantages:

• High Load Carrying Capacity: Optimized geometry for managing simultaneous radial and thrust loads.
• Separable Design: Simplifies installation, maintenance, and system adjustment.
• Precision Engineering: Reduced frictional heat and energy loss for improved powertrain efficiency.
• Robust Construction: High resistance to shock loads and deformation under extreme pressure.
• RICH Quality Standards: Built to meet exacting tolerances for the professional aftermarket.

Typical Applications:

• Automotive differential and transmission systems.
• Industrial gear reducers and conveyor drives.
• Agricultural machinery axle and wheel hub assemblies.
• Construction equipment drivetrain components.
