Taper roller bearing specifications

This Timken 30318 taper roller bearing measures 90 x 190 x 46.5 mm and is supplied new in a single pack. It is built for applications that require combined radial and axial load capacity. The unit carries a three-year parts and one-year labor coverage period.

Fitment and usage limits

Mechanics and engineers fitting this bearing into housings or shafts with matching dimensions will find it suitable. Installers who need a different bore, outside diameter or width must select another part number. The component is not intended for non-rotating or purely axial-thrust applications.

Critical dimension: 90 mm bore

The 90 mm bore is the single measurement that decides whether this bearing fits the shaft. Verify the shaft diameter before ordering; an incorrect bore size will prevent proper installation and operation.
