Product Overview: The 23248 Spherical Roller Bearing
The 23248 is a high-capacity Spherical Roller Bearing designed for the most demanding industrial applications. With key dimensions of 240mm Bore Diameter, 440mm Outer Diameter, and 160mm Thickness, this bearing is engineered to handle extreme radial and axial loads. As a key component of our 23200 Series, it is part of a family of robust Spherical Roller Bearings known for their reliability and performance under harsh conditions.
The defining feature of the 23248 bearing is its ability to accommodate significant shaft misalignment. This is achieved through its internal design, which features two rows of symmetrical barrel-shaped rollers and a common sphered raceway in the outer ring. This self-aligning capability prevents excessive stress on the bearing and surrounding components, ensuring a longer operational life and reducing maintenance requirements. Many variants of this bearing feature a tapered bore, allowing for secure mounting using an H 2348 adapter sleeve.
Key Features of the 23248 Bearing
- Exceptional Load Capacity: Designed to support very high radial loads and substantial axial loads in both directions.
- Self-Aligning Design: The spherical outer ring raceway allows the bearing to tolerate angular misalignment between the shaft and housing.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, fatigue resistance, and performance in contaminated environments.
- Two Symmetrical Roller Rows: The dual-row design with barrel-shaped rollers provides excellent load distribution and operational stability.
- Optimized for Heavy Industry: Engineered to withstand shock loads, vibration, and challenging operational conditions common in heavy machinery.
- Tapered Bore Compatibility: Often supplied with a tapered bore (e.g., 23248K) for easy and secure mounting on shafts using adapter or withdrawal sleeves.
Common Applications
- Mining and Construction: Used in heavy-duty equipment such as rock crushers, vibrating screens, and conveyor systems.
- Pulp and Paper Mills: Essential for machinery like press sections, calenders, and drying cylinders that operate under high loads and temperatures.
- Steel Manufacturing: Found in continuous casters, rolling mill stands, and other high-stress applications in steel production.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale industrial transmissions, ensuring smooth power transfer.
- Wind Turbines: Utilized in the main shafts and gearboxes of wind energy systems to handle fluctuating and heavy loads.
- Marine Propulsion: Suitable for propeller shafts and other critical applications in marine and offshore equipment.
- Cement Production: Deployed in grinding mills, kilns, and crushers where durability and reliability are paramount.
Benefits of Using the 23248 Bearing
