22220 EK C3 Double Row Self Aligning Spherical Roller Bearings
The heavy-duty self-aligning roller bearing perfect for mining equipment, industrial fans, steel mill rollers, and vibrating machinery, this bearing delivers exceptional durability, reduced maintenance, and reliable performance in the toughest operating environments.
Key Dimensions (mm):
- Bore Diameter (d): 100 mm
- Outer Diameter (D): 180 mm
- Width (B): 46 mm
- Load Ratings:
- Dynamic Load Rating (Cr): Approximately 490 kN (exact value depends on manufacturer standards). This high rating signifies its ability to handle severe dynamic radial loads over long service life.
- Static Load Rating (Cor): Approximately 550 kN, indicating excellent resistance to heavy static or slow-oscillation loads.
- Speed Ratings: Suitable for moderate to high rotational speeds.
- Material & Construction: Rings and rollers are manufactured from vacuum-degassed, high-carbon chromium bearing steel (SAE 52100), through-hardened for uniform hardness and deep stress resistance. Precision grinding ensures optimal spherical raceway and roller profiles.
Product Overview：
22220 EK C3 self-aligning roller bearing represents a critical solution for applications where extreme radial loads, shaft misalignment, and harsh operating conditions converge. This precision-engineered component is built to deliver unparalleled reliability and longevity.
Core Performance Advantages:
Automatic Self-Alignment & Misabsorption
The bearing’s defining feature is its ability to automatically correct for angular misalignment (typically up to ±1.5°). This compensates for shaft deflection, housing inaccuracies, and installation errors, eliminating edge stress and extending service life.Exceptional Load Capacity & Durability
The two rows of symmetrical barrel-shaped rollers provide an extremely high radial load rating. The solid cage ensures precise roller guidance under heavy load and high vibration, preventing roller skew and cage failure. This makes the 22220 EK C3 exceptionally robust for shock and impact loads.Operational Stability in Demanding Conditions
The optimized internal geometry and C3 clearance allow for stable operation under combined radial and axial loads, even in applications with significant thermal growth or vibration (e.g., vibrating screens, industrial fans).Extended Service Life & Reduced Downtim
By mitigating misalignment stress and utilizing high-grade materials, this bearing dramatically reduces wear rates. The result is longer maintenance intervals, lower total cost of ownership, and increased machinery availability.
Industrial Applications:
Material Processing
Conveyor head/tail pulleys, crushers, and grinding mills in mining and aggregate sectors.Steel Production
Roll neck bearings in continuous casters and rolling mills, where thermal expansion is significant.Power Generation & Heavy Machinery
Gearboxes, industrial fans, blowers, and crane sheaves.Pulp & Paper Industry
Dryer cylinder bearings in paper machines.- Vibrating Equipment
Screens, shakers, and compactors where dynamic misalignment is constant.
