NTN 30315 Tapered Roller Bearing

The ZIBOO NTN 30315 is a precision tapered roller bearing built for radial and axial load handling. Its 75x160x31mm profile suits industrial machinery, automotive hubs and heavy-duty gearboxes where combined forces are present. Mechanics and maintenance engineers select it for reliable rotation under demanding conditions.

Build quality and mounting implications

Hardened bearing steel races and rollers resist fatigue and wear across extended service intervals. The tapered geometry allows straightforward press-fit installation onto shafts and into housings without specialised tooling. Red finish on the packaging identifies the component quickly in a busy workshop or stores bin.

Included accessories and practical effect

Supplied as a single unit in a protective box to prevent contamination before fitting. A three-year parts guarantee and one-year labour coverage reduce downtime risk for critical equipment. No lubricant or seals are bundled, so the installer chooses the grease type matched to operating temperature and speed.

Questions about this item

What are the exact inner, outer and width dimensions of the 30315 bearing?

The 30315 tapered roller bearing has a 75 mm inner diameter, a 160 mm outer diameter and a 31 mm width.

What housing bore and shaft diameter does the 30315 bearing require for a standard press fit?

A standard press fit needs a 160 mm housing bore and a 75 mm shaft seat to match the 30315 bearing dimensions.

How is the 30315 bearing mounted and which step is most often done incorrectly?

Press the inner ring onto the 75 mm shaft and the outer ring into the 160 mm housing using a sleeve that contacts only the ring being driven; the common error is hammering directly on the rollers or cage.
