Product Overview: The 22244 Spherical Roller Bearing
The 22244 is a high-capacity spherical roller bearing, a key component in our Spherical Roller Bearings collection and a part of the robust 22200 Series. With principal dimensions of 220mm Bore Diameter, 400mm Outer Diameter, and 108mm Thickness, this bearing is engineered to withstand extreme conditions. Its design features two rows of symmetrical barrel rollers and a common sphered outer ring raceway, which allows it to accommodate significant shaft misalignment and deflection without compromising performance. This self-aligning capability makes it indispensable in heavy-duty industrial applications where precision and durability are paramount.
Manufactured to exacting industry standards, the 22244 bearing is designed to handle very heavy radial loads and substantial axial loads in both directions. It is a go-to solution for machinery operating in harsh environments, ensuring long service life and exceptional operational reliability. Explore our full range of heavy-duty bearings to find the perfect solution for your most demanding industrial needs.
Key Features of the 22244 Bearing
- Superior Load Capacity: Designed with two rows of rollers to manage extremely high radial and heavy axial loads.
- Self-Aligning Design: The sphered outer raceway compensates for angular misalignment between the shaft and housing, reducing stress and extending bearing life.
- Robust Construction: Typically manufactured with a strong cage (e.g., steel or brass) to withstand high speeds, shock loads, and vibration.
- Optimized Roller Profile: The barrel-shaped rollers ensure optimal stress distribution along the line of contact, preventing edge stresses and enhancing durability.
- Dimensional Stability: Heat-treated to operate reliably across a wide range of temperatures without losing its structural integrity.
- Low-Friction Operation: Engineered for smooth performance, which minimizes heat generation and improves overall machine efficiency.
Common Applications of 22244 Bearings
- Mining and Construction: Widely used in crushers, vibrating screens, conveyors, and heavy earth-moving equipment.
- Pulp and Paper Industry: Essential for machinery such as paper machine rolls, calenders, and press sections.
- Industrial Gearboxes: Provides reliable support for gears and shafts in large-scale industrial transmissions.
