40x80x23 Self Aligning Roller Bearings High Load 22208 Bearing For Heavy Machinery

The 22208 self-aligning roller bearing is an essential mechanical component engineered to handle complex load scenarios and operational challenges, ensuring reliable machinery performance. With dimensions of 40mm inner diameter, 80mm outer diameter, and 23mm width, this bearing is ideal for applications requiring management of both radial and axial loads while accommodating misalignment issues.

Features two rows of drum-shaped rollers manufactured from high-carbon chromium bearing steel (GCr15). The precision-crafted rollers provide excellent surface finish and tight dimensional tolerances, offering enhanced radial load capacity and even load distribution.

The inner ring contains two raceways while the outer ring features a spherical raceway that enables self-alignment. Advanced heat treatment provides surface hardness of HRC58-64 for superior wear and fatigue resistance.

High-strength steel cage with precise pockets separates and guides rollers, ensuring smooth operation. Special coatings and treatments enhance durability in harsh environments.

• High Radial Load Capacity: Double-row roller design with large contact area handles substantial radial loads for heavy-duty applications
• Axial Load Capability: Manages axial loads in both directions, suitable for gearbox systems and conveyor drives
• Self-Aligning Function: Spherical outer raceway compensates for shaft/housing misalignment, reducing stress concentrations
• High-Speed Stability: Optimized design ensures smooth operation at elevated speeds with proper lubrication

• Industrial Machinery: Large motors, conveyor systems, industrial gearboxes
• Mining & Construction: Crushers, excavators, loaders operating in harsh conditions
• Power Generation: Generator and turbine rotor support systems
• Transportation Equipment: Truck and bus axle support systems

Use high-quality lithium-based grease for general applications, or synthetic greases/oil-based lubricants for high-temperature/high-load conditions. Fill approximately one-third to one-half of bearing internal space and maintain regular lubrication intervals.

Conduct visual inspections for cracks, corrosion, or abnormal wear. Monitor vibration and temperature levels to detect lubrication issues, excessive load, or misalignment.

Maintain clean environment during installation. Use proper tools and ensure correct fit: interference fit for inner ring/shaft, clearance fit for outer ring/housing to preserve self-aligning function.

Store in clean, dry, ventilated area protected from moisture and extreme temperatures. Keep in original packaging or anti-rust paper, positioned horizontally to prevent stress concentration.
