Cylindrical roller bearings are rolling bearings specifically engineered to accommodate high radial loads. Their key rolling elements are cylindrical rollers that make linear contact with the raceways. This design makes them exceptionally effective at handling pure radial forces, serving as critical components in a vast array of industrial applications. Compared to ball bearings of the same size, they offer significantly higher radial load-carrying capacity.

Structure of Cylindrical Roller Bearings
- A typical cylindrical roller bearing consists of the following main components:
- Outer Ring:Usually features fixed ribs or flanges on one or both sides to provide axial guidance for the rollers.
- Inner Ring:Also typically has ribs or flanges for roller guidance. Depending on the design, the inner ring can be integral with ribs or separable (facilitating mounting).
- Cylindrical Rollers:Precision-ground cylindrical rolling elements that are the core load-carrying components. Roller length is usually slightly less than their diameter.
- Cage (Retainer):Separates the rollers evenly, prevents them from rubbing against each other, and guides them correctly within the raceways. Cage materials include steel, brass, or polymers (e.g., polyamide/nylon).
