TIMKEN 67391/67322 Tapered Roller Bearing Set 133.35x196.85x46.038

Applications

The TIMKEN 67391/67322 is a matched tapered roller bearing set designed for heavy-duty rotating shafts, drive systems, gear transmissions, wheel hubs, and industrial powertrain assemblies. Due to its high load-carrying capacity, it is commonly used in mining equipment, metallurgical processing, heavy vehicles, agricultural machinery, rail transport components, and industrial gearboxes.

The tapered geometry allows the bearing to support combined radial and axial loads, providing stable shaft alignment and reliable operation even under shock loads, vibration, variable speeds, and temperature fluctuations.

Key Advantages

• Very high load capacity due to tapered roller and raceway profile.

• Stable axial guidance for maintaining shaft alignment under load.

• Engineered for continuous operation in demanding and heavy-duty environments.

• Excellent resistance to wear and fatigue, ensuring long service life.

• Manufactured by TIMKEN - a global leader in premium industrial bearings.
