Product Overview: The 2308 Self-Aligning Ball Bearing
The 2308 bearing is a high-capacity self-aligning ball bearing with dimensions of 40x90x33mm. As a key component in our 2300 Series, it belongs to the wider category of Self-Aligning Ball Bearings. This bearing is engineered to handle significant shaft deflection and misalignment between the shaft and housing. Its 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 alignment errors. This capability makes the 2308 indispensable for applications where maintaining perfect alignment is challenging.
Manufactured to exacting industry standards, the 2308 offers superior reliability and a long service life, even in demanding operational environments. Its robust construction ensures it can accommodate both static and dynamic misalignment, making it a versatile solution for a wide range of industrial machinery. For applications requiring mounting on tapered shafts, this bearing is often used with an H 2308 adapter sleeve.
Key Features of the 2308 Bearing
- Automatic Self-Alignment: The spherical outer raceway allows the bearing to compensate for angular misalignment, reducing stress and wear.
- Robust Load Capacity: The dual-row ball design provides a high capacity for radial loads and moderate axial loads in both directions.
- Wide Design: Part of the 2300 series, it has a greater width than the 1200 or 1300 series, enhancing its load-carrying capability.
- Low Friction: Precision engineering ensures minimal friction during operation, leading to lower operating temperatures and increased efficiency.
- Durable Construction: Made from high-purity, hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- Mounting Versatility: Available in both cylindrical and tapered bore (K suffix) versions to accommodate different mounting arrangements, often with adapter sleeves.
Common Applications of 2308 Bearings
- Agricultural Machinery: Ideal for equipment like combines, balers, and tillers that operate on uneven terrain, causing shaft flexing.
- Conveyor Systems: Used in conveyor pulleys and rollers where long shafts can deflect under heavy loads.
- Industrial Fans and Blowers: Accommodates misalignment caused by thermal expansion or structural flexing in large ventilation systems.
- Mining and Construction Equipment: Provides reliable support in crushers, screeners, and vehicles where harsh conditions cause frame distortion.
- Pulp and Paper Processing: Suitable for machinery with long rollers where maintaining precise alignment is difficult.
- Textile Machinery: Ensures smooth operation of shafts and rollers in looms and spinning machines.
- Food Processing Equipment: Used in mixers and other machinery where robust, reliable performance is critical.
Benefits of Using the 2308 Bearing
- Enhanced Machine Reliability: By accommodating misalignment, it reduces stress on shafts and other components, preventing premature failures.
- Extended Service Life: The self-aligning feature minimizes edge stresses on the balls, leading to a longer operational lifespan for the bearing.
- Reduced Maintenance Costs: Its durability and resistance to misalignment-related damage mean fewer replacements and less downtime.
- Improved Operational Efficiency: Low-friction characteristics contribute to smoother machinery operation and potential energy savings.
- Simplified Assembly: The ability to self-align can simplify the initial machine assembly process, especially in complex systems.
- Versatile Performance: Capable of performing reliably in environments with vibration, shaft deflection, and alignment errors.
