Product Overview: The 22218 Spherical Roller Bearing
The 22218 bearing is a high-performance component within our extensive 22200 Series Spherical Roller Bearings collection. With precise dimensions of 90mm bore diameter, 160mm outer diameter, and 40mm thickness, this bearing is engineered to excel in demanding industrial applications. Spherical roller bearings are renowned for their exceptional load-carrying capabilities, handling both heavy radial loads and significant axial loads in either direction.
Its key feature is the ability to accommodate angular misalignment, whether static or dynamic, between the shaft and the housing. This makes the 22218 bearing an ideal choice for machinery where structural deflections or mounting errors are anticipated. As a trusted supplier of industrial bearings, we ensure our 22218 bearings meet rigorous industry standards, providing reliable, long-lasting performance crucial for uninterrupted operations. For optimal installation and secure fitting, compatible accessories such as adapter sleeves like the H 318 or AHX 318 and lock nuts like the KM 18 or MB 18 are often used.
Key Features of the 22218 Bearing
- High Load Capacity: Designed to carry extremely heavy radial loads and substantial axial loads in both directions.
- Self-Aligning Capability: Automatically compensates for angular misalignment between the shaft and the housing, reducing stress and extending life.
- Robust Roller Design: Features two rows of barrel-shaped rollers, providing excellent load distribution and shock resistance.
- Durable Construction: Manufactured from high-quality bearing steel for superior wear resistance and long operational life.
- Low Friction: Engineered to minimize rotational friction, leading to reduced heat generation and improved energy efficiency.
- Vibration Damping: The internal geometry helps to dampen vibrations, contributing to smoother machine operation.
