Product Overview: The 2211 Self-Aligning Ball Bearing
The 2211 Self-Aligning Ball Bearing is a robust and reliable component, specifically engineered to operate effectively in applications where shaft deflection or misalignment is a concern. With principal dimensions of a 55mm bore diameter, 100mm outer diameter, and 21mm 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 the housing, ensuring smooth operation and preventing premature wear.
Manufactured from high-grade bearing steel, the 2211 is built for durability and longevity in demanding industrial environments. It is an indispensable part for machinery where maintaining precise alignment is challenging.

Key Features of the 2211 Bearing
- Automatic Self-Alignment: Ingeniously designed to accommodate both static and dynamic angular misalignments, reducing stress on the shaft and extending component life.
- Dual Row Design: Two rows of balls provide a higher radial load capacity compared to single-row bearings.
- Low-Friction Performance: The internal geometry is optimized to minimize rotational friction, leading to lower operating temperatures and reduced energy consumption.
- Durable Construction: Made from high-quality, through-hardened bearing steel for superior strength and resistance to wear and fatigue.
- Versatile Mounting: Can be mounted directly onto a stepped shaft or onto a cylindrical shaft using an adapter sleeve like the H 311.
- Reduced Maintenance Needs: Its ability to handle misalignment minimizes the risk of bearing failure, leading to less downtime and lower maintenance costs.
Common Applications of 2211 Bearings
- Agricultural Machinery: Widely used in equipment such as combines, balers, and tractors where shafts are long and prone to flexing.
- Conveyor Systems: Ideal for pulleys and rollers in long conveyor belts where structural sagging can cause misalignment.
- Industrial Fans and Blowers: Ensures smooth and quiet operation by compensating for imbalances or shaft deflections at high speeds.
- Textile and Printing Machinery: Provides reliable support for rollers and shafts, maintaining operational precision despite vibrations and alignment shifts.
- Mining and Construction Equipment: Suitable for crushers, screens, and mixers that operate in harsh conditions with heavy loads and potential housing distortions.
- Food Processing Equipment: Used in machinery where cleanliness and reliability are critical, and operational misalignments may occur.
Benefits of Using the 2211 Bearing
- Enhanced Machine Reliability: By compensating for misalignment, the bearing reduces stress on other machine components, leading to fewer breakdowns.
- Extended Service Life: The self-aligning feature prevents edge loading on the balls, significantly increasing the operational life of the bearing.
- Simplified Installation: The bearing's tolerance for misalignment can simplify the machine design and assembly process, saving time and cost.
- Improved Performance Under Load: Maintains efficient operation even when the shaft deflects under heavy or fluctuating loads.
- Cost-Effective Solution: Reduces the need for frequent replacements and costly maintenance, offering excellent long-term value.
- Operational Versatility: Performs reliably across a wide range of speeds and operating conditions, making it suitable for diverse industrial applications.
