Product Overview: The 22317 Spherical Roller Bearing
The 22317 Spherical Roller Bearing is a high-capacity component engineered to excel in the most demanding industrial environments. With dimensions of 85mm bore diameter, 180mm outer diameter, and 60mm thickness, this bearing is part of our robust 22300 Series of Spherical Roller Bearings. Its design features two rows of symmetrical barrel-shaped rollers and a common sphered outer ring raceway, which allows it to accommodate significant shaft misalignment and deflection. This self-aligning capability is crucial for applications where maintaining perfect alignment is challenging.
As a leading supplier of industrial mechanical parts, we ensure our 22317 bearings are manufactured to the highest standards, offering exceptional reliability and a long service life. This bearing is specifically designed to handle very heavy radial loads and considerable axial loads in both directions, making it an indispensable part of heavy machinery and equipment.
Key Features of the 22317 Bearing
- Excellent Self-Aligning Capability: The spherical outer raceway allows the bearing to tolerate angular misalignment between the shaft and housing, reducing stress and extending component life.
- High Radial and Axial Load Capacity: The dual-row roller design is optimized to support extremely heavy radial loads and substantial axial loads from any direction.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and performance under shock loads.
- Low Friction Design: Precision engineering of the rollers and raceways ensures minimal friction and heat generation, leading to efficient operation.
- Dimensional Stability: Heat-treated to operate reliably across a wide range of temperatures without significant dimensional changes.
- Compatibility with Sleeves: Can be mounted directly on a stepped shaft or used with an H 2317 adapter sleeve for mounting on smooth shafts.
Common Applications
- Mining and Construction: Widely used in rock crushers, vibrating screens, conveyors, and heavy earth-moving equipment.
- Pulp and Paper Industry: Essential for paper machine rollers, press sections, and other high-load rotating components.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale industrial transmissions, ensuring smooth power transfer.
- Wind Turbines: Used in the main shafts and gearboxes of wind energy systems to handle fluctuating, heavy loads.
- Metal Processing: Found in continuous casting machines, rolling mills, and other steel and metalworking machinery.
- Marine and Offshore: Suitable for ship propulsion systems, winches, and cranes where reliability in harsh environments is critical.
- Large Fans and Blowers: Supports heavy rotating assemblies in industrial ventilation and air-handling systems.
Benefits of Using the 22317 Bearing
- Enhanced Machine Reliability: Reduces the risk of premature failure by effectively managing misalignment and heavy loads, leading to less downtime.
- Extended Service Life: The bearing's ability to handle tough conditions translates to a longer operational lifespan for both the bearing and the machinery.
- Reduced Maintenance Costs: Durable design and tolerance for misalignment minimize the need for frequent inspections, repairs, and replacements.
- Superior Performance in Harsh Conditions: Built to withstand vibration, shock loads, and contamination, making it ideal for heavy-duty applications.
- Simplified Assembly: The self-aligning nature can simplify the mounting process, especially in large or complex machinery where achieving perfect alignment is difficult.
