Product Overview: The 22211 Spherical Roller Bearing
The 22211 bearing is a high-capacity, double-row spherical roller bearing engineered to withstand the most demanding industrial conditions. With key dimensions of 55x100x25mm, this component is part of our robust 22200 Series and a prime example of our premium Spherical Roller Bearings. Its unique internal design, featuring two rows of symmetrical barrel rollers and a common sphered outer ring raceway, allows it to accommodate significant shaft misalignment and deflection. This self-aligning capability is crucial in applications where maintaining perfect alignment is challenging, preventing premature wear and extending machinery life.
As a specialist supplier of industrial components, we ensure our 22211 bearings are manufactured to precise standards, delivering exceptional performance under heavy radial and moderate axial loads in both directions. This bearing is a cornerstone component in heavy machinery across various sectors, ensuring reliability and operational efficiency where it matters most.
Key Features of the 22211 Bearing
- Self-Aligning Design: Automatically compensates for angular misalignment between the shaft and housing, reducing stress on the bearing and other machine components.
- High Load Capacity: Engineered with two rows of rollers to support heavy radial loads and significant axial loads in both directions.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and performance in harsh environments.
- Optimized Internal Geometry: Designed to minimize friction and heat generation, leading to a longer service life and improved operational efficiency.
- Versatile Application Range: Suitable for a wide variety of heavy-duty industrial applications where reliability is paramount.
- Dimensional Stability: Precision-engineered to maintain its shape and performance even under high temperatures and fluctuating loads.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high loads and potential misalignments common in power transmission systems.
- Mining and Construction Equipment: Used in crushers, vibrating screens, and conveyors where bearings are subjected to extreme loads, shock, and contamination.
- Pulp and Paper Machinery: Ideal for use in rollers and processing equipment that operate in demanding, high-moisture environments.
