ARB Tapered Roller Bearings Guide
Product Description
The American Roller Bearing 220TDI778 double-row tapered roller bearing consists of a double inner ring with two rows of tapered rollers and cages, two single outer rings, and an outer ring spacer. The spacer is used to set the required axial play and includes a lubrication groove and oil holes for lubricant distribution. The two-row tapered roller design provides high radial load capacity and supports axial loads in both directions, while its internal geometry makes it suitable for applications where some shaft deflection is expected under load. It is commonly used in industrial gearboxes, rolling equipment, heavy machinery, and other applications requiring high radial load capacity, bidirectional axial support, and adjustable axial play.
