Product Overview: The 2218 Self-Aligning Ball Bearing
The 2218 Self-Aligning Ball Bearing is a robust component engineered to perform in applications where shaft deflection or misalignment is a concern. With primary dimensions of 90mm Bore Diameter, 160mm Outer Diameter, and 40mm Thickness, this bearing is a key part of our 2200 Series. Its design features two rows of balls and a common sphered raceway in the outer ring, which allows the bearing to automatically correct for angular misalignment between the shaft and housing. This capability is crucial for preventing excessive stress and premature wear on machinery components.
As a specialist supplier of industrial parts, we provide high-quality 2218 bearings manufactured to precise industry standards. This ensures reliable and efficient operation in a wide range of demanding industrial environments.

Key Features of the 2218 Bearing
- Misalignment Compensation: Expertly designed to accommodate both static and dynamic angular misalignments, ensuring smooth operation.
- Dual-Row Design: Two rows of balls provide a higher radial load capacity compared to single-row bearings.
- Low-Friction Performance: Engineered to minimize rotational friction, reducing heat generation and energy consumption.
- Robust Steel Construction: Manufactured from high-grade bearing steel for exceptional durability and long service life.
- Standardized Dimensions: Conforms to industry-standard dimensions for easy interchangeability and system integration.
- Tapered Bore Option: Often available with a tapered bore (designated with a 'K' suffix) for mounting with an adapter sleeve on cylindrical shafts.
Common Applications
- Agricultural Machinery: Ideal for equipment like combines and balers that operate on uneven terrain, causing shaft flex.
- Conveyor Systems: Effectively used in long conveyor belts where structural sagging can lead to misalignment.
- Industrial Fans and Blowers: Supports fan shafts, compensating for imbalances or structural shifts to reduce vibration and noise.
- Mining and Construction: Endures the harsh conditions and heavy loads in crushers, screeners, and other heavy equipment.
- Pulp and Paper Mills: Suitable for rollers and machinery where moisture and operational stress can cause alignment issues.
- Textile Machinery: Ensures the smooth rotation of spindles and rollers, even when minor shaft deflections occur.
Benefits of Using the 2218 Bearing
- Increased Machine Uptime: By compensating for misalignment, the bearing reduces stress on other components, leading to fewer breakdowns.
- Extended Component Lifespan: The self-aligning feature minimizes wear and tear, prolonging the operational life of both the bearing and the machine.
- Reduced Maintenance Costs: Its durability and resistance to misalignment-related failures lower the frequency of costly repairs and replacements.
- Improved Operational Efficiency: Low friction operation contributes to smoother performance and potential energy savings.
- Simplified Assembly: The ability to self-align makes the mounting process faster and less critical, especially in complex assemblies.
- Reliable in Demanding Conditions: Consistently performs in environments with vibration, shaft deflection, and potential installation errors.
