Product Overview: The 2216 Self-Aligning Ball Bearing
The 2216 bearing is a robust and efficient component within our 2200 Series of Self-Aligning Ball Bearings. Engineered with principal dimensions of 80x140x33mm, this bearing is specifically designed to manage applications where shaft deflection or misalignment between the shaft and housing is a concern. Its innovative design features a spherical outer ring raceway and two rows of balls, which allows the inner ring, balls, and cage to rotate freely around the bearing center, automatically correcting for angular misalignments.
As a premier supplier of industrial mechanical parts, we ensure our 2216 bearings meet stringent industry standards for performance and durability. This bearing is essential for maintaining smooth and reliable operation in a wide array of machinery, particularly in environments where maintaining perfect alignment is challenging. The 2216 is typically supplied with a tapered bore for mounting with an adapter sleeve, such as the H 316, ensuring a secure fit on the shaft.
Key Features of the 2216 Bearing
- Self-Aligning Capability: Automatically compensates for both static and dynamic angular misalignment, reducing stress on the shaft and extending the bearing's service life.
- Dual Ball Rows: Two rows of balls provide a high capacity for radial loads and moderate axial loads in both directions.
- Low Friction: The design minimizes rotational friction, resulting in lower operating temperatures and improved energy efficiency.
- Tapered Bore Design: Commonly features a tapered bore (suffix K) for secure mounting on shafts using adapter sleeves.
- Robust Construction: Manufactured from high-quality bearing steel for superior hardness, wear resistance, and longevity under demanding conditions.
- Reduced Maintenance Needs: The ability to accommodate misalignment reduces the risk of premature failure, leading to less frequent maintenance.
Common Applications
- Agricultural Machinery: Widely used in harvesters, tractors, and other farm equipment where shafts are long and prone to flexing.
- Conveyor and Belt Systems: Ideal for supporting rollers in long conveyor lines where structural sagging can cause misalignment.
- Industrial Fans and Blowers: Ensures smooth operation in large ventilation systems where shaft deflection can occur at high speeds.
- Textile and Printing Machinery: Provides reliable support for rollers and cylinders, maintaining precision despite slight alignment shifts.
- Mining and Construction Equipment: Suitable for heavy-duty machinery like crushers and screening machines that operate in harsh environments.
- Pulp and Paper Mills: Effectively used in processing machinery where moisture and operational stress can affect alignment.
- Food Processing Equipment: Offers dependable performance in machinery that requires both robustness and the ability to handle operational variations.
Benefits of Using the 2216 Bearing
- Enhanced Equipment Lifespan: By accommodating misalignment, the bearing reduces wear and tear on itself and other machinery components.
- Improved Operational Reliability: Minimizes the risk of bearing failure due to shaft deflection, leading to less unexpected downtime.
- Simplified Assembly: The self-aligning nature makes the initial mounting process more forgiving, especially in complex assemblies.
- Cost-Effective Solution: Reduces overall maintenance and replacement costs by providing a durable, long-lasting performance.
- Versatile Performance: Capable of handling a combination of loads and alignment challenges, making it suitable for a broad range of industrial uses.
- Efficient Operation: Low-friction characteristics contribute to smoother machine performance and potential energy savings.
