Product Description

The 18690/18620 Koyo (JTEKT) tapered roller bearing is a single-row configuration featuring conical raceways and tapered rollers positioned between the inner and outer rings. This design enables the bearing to accommodate combined radial and axial loads effectively, with increased contact angles enhancing axial load capacity.

Assembly and disassembly are straightforward due to its two-part construction, comprising a cup (outer ring) and cone (inner ring, cage, and roller set). The open design of single-row tapered roller bearings requires installation in mirror-image arrangement alongside a corresponding bearing. Paired sets may be configured in X, O, or tandem arrangements to meet specific application requirements.
