Product Overview: The 22228 Spherical Roller Bearing
The 22228 Spherical Roller Bearing is a high-capacity, double-row, self-aligning bearing designed for the most demanding industrial applications. With key dimensions of a 140mm bore diameter, 250mm outer diameter, and 68mm width, this component is a crucial part of our 22200 Series within the broader Spherical Roller Bearings collection. Its unique internal design, featuring two rows of symmetrical barrel-shaped rollers in a common sphered outer raceway, allows it to accommodate significant shaft misalignment and deflection without compromising performance. This makes the 22228 an essential solution for heavy-duty machinery where precision and reliability are paramount.
Key Features of the 22228 Bearing
- Self-Aligning Capability: Automatically compensates for angular misalignment between the shaft and housing, reducing stress on the bearing and adjacent components.
- High Load-Carrying Capacity: The double-row roller design provides exceptional capacity for handling heavy radial loads and moderate axial loads in both directions.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior durability, wear resistance, and long service life under extreme conditions.
- Optimized Internal Design: Engineered for low friction and minimal heat generation, ensuring efficient operation and extending lubrication intervals.
- Versatile Mounting: Typically features a tapered bore for secure mounting on shafts using an adapter sleeve, such as the H 2328, or a withdrawal sleeve.
- Durable Cage: Equipped with a strong steel or brass cage that accurately guides the rollers, providing stability even with high speeds, vibrations, and shock loads.
Common Applications
- Mining and Construction: Ideal for heavy machinery like crushers, vibrating screens, conveyors, and excavators where heavy loads and misalignment are common.
- Pulp and Paper Mills: Used in demanding applications such as calendar rolls, press sections, and drying cylinders.
- Industrial Gearboxes: Provides reliable support for gears and shafts in high-torque power transmission systems.
- Steel Manufacturing: Essential for continuous casting machines, rolling mill stands, and other high-temperature, heavy-load equipment.
- Wind Turbines: Supports the main rotor shaft and gearbox components, withstanding fluctuating loads and environmental stresses.
- Marine and Offshore: Suitable for propulsion systems, winches, and cranes that operate in harsh, corrosive environments.
Benefits of Using the 22228 Bearing
- Increased Machine Uptime: The bearing's ability to handle misalignment and heavy loads prevents premature failures, leading to enhanced operational reliability.
- Extended Service Life: Superior materials and design reduce wear and friction, resulting in a longer operational lifespan for both the bearing and the equipment.
- Reduced Maintenance Costs: The robust and reliable nature of the 22228 bearing minimizes the need for frequent inspections, repairs, and replacements.
- Improved Performance: Ensures smooth and efficient operation even under severe conditions, including shock loads, vibration, and contamination.
- Operational Versatility: Its high-performance characteristics make it suitable for a wide array of heavy industrial sectors and applications.
