23120CA Spherical Roller Bearing Self Aligning High Load Capacity Bearing 100x165x52

23120CA Spherical Roller Bearing with 100mm Bore, 165mm OD, 52mm Width - High Load Capacity

I. Basic Information

• Bearing Type: Double-row spherical roller bearing
• Model Interpretation: "231" stands for the bearing series; "20" indicates the inner diameter size (inner diameter = 20 * 5 = 100mm); "CA" means it is equipped with a brass solid cage and has a cylindrical bore design.

III. Structural and Performance Features

1. Structural Design

• Self-aligning Structure: The outer ring raceway is spherical (with the center of the bearing as the center of the sphere), and the inner ring contains two rows of raceways. Cooperating with the barrel-shaped rollers, it can automatically compensate for shaft deflection, installation errors, and misalignment (allowing an aligning angle of 1°-2.5°), thus reducing additional stress and wear.
• Cage: The brass solid cage (CA) has low noise and certain self-lubricating properties, which can stably carry the rollers and adapt to working conditions with multiple rolling elements and limited space.
• Rolling Elements: The barrel-shaped rollers are in linear contact with the raceways, enabling them to bear large radial loads and bidirectional axial loads.

2. Core Performance

• High Load-carrying Capacity: Suitable for heavy-load and impact load scenarios, meeting the strict load requirements of heavy machinery.
• Wear Resistance and Fatigue Resistance: Made of high-quality bearing steel and processed through professional heat treatment, it can operate stably for a long time in harsh environments (such as high temperature and dusty conditions) and has a long service life.
• Stable Operation: The structural design reduces vibration and noise, improving the operation accuracy of the equipment.

IV. Application Fields

• Mining machinery (crushers, vibrating screens, etc.)
• Metallurgical equipment (rolling mill gearboxes, continuous casters, etc.)
• Papermaking machinery (various load-bearing components of paper machines)
• Power equipment (hydraulic generators, vertical motors, etc.)
• Construction machinery (tower cranes, mills, etc.)

V. Supplementary Parameters

• Basic rated radial dynamic load: 287kN
• Limiting Speed: 2000rpm (grease lubrication), 2800rpm (oil lubrication)
• Weight: Approximately 4.42kg
