Product Overview: The 22218 Spherical Roller Bearing
The 22218 bearing is a high-capacity, double-row, self-aligning roller bearing engineered to withstand severe operating conditions. With principal dimensions of a 90mm bore diameter, a 160mm outer diameter, and a 40mm thickness, this component is a key part of our Spherical Roller Bearings collection and the 22200 Series. Its design features two rows of symmetrical barrel rollers and a common sphered raceway in the outer ring. This allows the bearing to tolerate angular misalignment of the shaft relative to the housing, making it ideal for applications involving heavy loads, shock, and potential shaft deflection.
Manufactured from high-grade bearing steel, the 22218 is built for reliability and a long service life in the most demanding industrial environments. It is an indispensable component in machinery where robustness and the ability to handle combined radial and axial loads are critical.

Key Features of the 22218 Bearing
- Self-Aligning Capability: Automatically compensates for dynamic and static misalignment, reducing stress on the shaft and extending machine life.
- High Load Capacity: Engineered to accommodate very heavy radial and significant axial loads in both directions.
- Robust Construction: Made from ultra-clean, high-hardness bearing steel for maximum durability and resistance to wear and fatigue.
- Two-Row Roller Design: Symmetrical barrel rollers provide excellent load distribution and operational stability.
- Optimized for Heavy Industry: Designed to perform reliably under shock loads, vibrations, and harsh environmental conditions.
- Low Friction Operation: Precision engineering ensures minimal rotational friction, which reduces operating temperature and energy consumption.
Common Applications of 22218 Bearings
- Mining and Construction: Used in rock crushers, vibrating screens, conveyor systems, and heavy-duty gearboxes.
- Pulp and Paper Mills: Essential for rollers in press sections, calendars, and other processing machinery.
- Steel Manufacturing: Found in continuous casting machines, rolling mill stands, and conveyor rollers where heavy loads are constant.
- Industrial Fans and Blowers: Provides reliable support for large fan shafts, accommodating misalignment caused by thermal expansion.
- Gearboxes and Transmissions: Ideal for supporting gears and shafts in large-scale industrial power transmission systems.
- Marine and Offshore Equipment: Used in propulsion systems, winches, and cranes that operate in challenging conditions.
- Wind Turbines: Supports the main shaft and gearbox components, handling the immense and fluctuating loads.
Benefits of Using the 22218 Bearing
- Enhanced Machine Uptime: The bearing's ability to handle misalignment and heavy loads reduces the risk of premature failure and costly downtime.
- Extended Service Life: Superior design and materials contribute to a longer operational lifespan, even under extreme stress.
- Reduced Maintenance Costs: High reliability and durability mean less frequent inspection, lubrication, and replacement.
- Improved Performance: Ensures smooth and stable operation of machinery, leading to better end-product quality and efficiency.
- Versatile and Adaptable: Suitable for a wide array of heavy-duty applications, providing a flexible solution for complex engineering challenges.
- Increased Safety: Robust design minimizes the chance of catastrophic bearing failure in critical machinery.
