Journal bearings are a type of cylindrical roller bearing designed for heavier radial load capacities, comprising of an inner and outer ring encasing a roller assembly that can be either separable or non-separable. These bearings are often used for high radial load, low-speed applications. A variety of designs and features are available, including width variations, oil holes, and key notches for different applications and industries. These bearings
are suitable for uses featuring oscillating motion, interrupted starting and stopping, and axial motion. They provide multiple benefits such as self-lubrication
, reducing maintenance and cost requirements. Journal bearings are widely used in industries such as corrugating machinery, forging equipment, table rolls, and line shafts
, and are often designed to interchange with multiple manufacturers, making replacement smooth and simple. Metric and Imperial designs are available, as well as different cage materials like steel or bronze. Variations such as cage material, size, and lubrication will impact bearing performance and durability. MRO Supply carries a multitude of journal roller bearing styles, materials, brands, and accessories such as casings and sleeves.
