Product description

The 25581/25520 Koyo (JTEKT) is a single-row tapered roller bearing, using tapered rollers positioned between the inner and outer rings with conical raceways. This structure permits the bearing to accommodate combined radial and axial loads in one direction. Bearings with larger contact angles offer greater axial load capacity. The bearing consists of a cup (outer ring) and a cone unit (inner ring with cage and roller set), which can be assembled or disassembled as needed. It has an open design and typically requires installation in a mirror-image arrangement with a second tapered roller bearing. These bearings may also be used in X, O, or tandem arrangements when paired.
