ZIBOO NTN 30328 Tapered Roller Bearing 140x300x53mm

Precision Tapered Roller Bearing

The ZIBOO NTN 30328 is a tapered roller bearing built to handle combined radial and axial loads in rotating equipment. Its geometry suits applications where shaft alignment and load distribution are critical. Engineers and maintenance teams select this unit for gearboxes, axle assemblies and heavy-duty machinery.

Standard Dimensions Define Fit

The bearing measures 140 mm bore, 300 mm outside diameter and 53 mm width, so it only fits housings and shafts machined to those exact tolerances. Axial load capacity depends on the contact angle inherent to the 30328 series, limiting use in purely thrust-heavy roles. Installers must verify clearance and lubrication requirements before assembly.
