Product Overview: The 22340 Spherical Roller Bearing
The 22340 Spherical Roller Bearing is an exceptionally robust component designed for the most demanding industrial applications. With principal dimensions of 200mm Bore Diameter, 420mm Outer Diameter, and 140mm Thickness, this bearing is engineered to support extremely high radial loads and moderate axial loads in both directions. As a key part of our 22300 Series, it belongs to the versatile family of Spherical Roller Bearings, renowned for their self-aligning capabilities.
The bearing's internal design, featuring two rows of symmetrical barrel-shaped rollers and a common sphered outer ring raceway, allows it to accommodate significant shaft deflection and misalignment between the shaft and housing. This self-aligning feature is critical in applications where operational conditions are harsh and maintaining perfect alignment is challenging. Manufactured from high-purity, hardened bearing steel, the 22340 provides superior durability and an extended service life even under severe shock loads and vibrations.
Key Features of the 22340 Bearing
- Exceptional Load Capacity: Designed with two rows of rollers to handle very heavy radial loads and substantial axial forces.
- Self-Aligning Capability: The spherical outer raceway compensates for angular misalignment, reducing stress on the bearing and increasing machinery uptime.
- Robust Construction: Manufactured from premium-grade bearing steel for maximum toughness, wear resistance, and longevity.
- Optimized Internal Geometry: Reduces friction and heat generation, leading to more efficient operation and lower energy consumption.
- Dimensional Stability: Heat-treated to ensure stability and reliable performance across a wide range of operating temperatures.
- High-Precision Engineering: Manufactured to tight tolerances for consistent and predictable performance in critical machinery.
