NTN U GB series tapered roller bearings are single-row roller units that handle radial and axial loads in one direction. The tapered raceway and the oblique contact between rollers and raceways distribute the load over a larger surface than in a deep groove ball bearing. They are used in pairs or matched sets to position shafts and absorb combined forces in transmissions, reducers and plant equipment.

The designation of this series is read in blocks: the initial number indicates the size and dimensional series, and the U and GB suffixes define the internal design and the finish of the assembly. In examples 30313U2GB, 30314U2GB, 30315U2GB, 30316U2GB and 30317U2GB you can see how the size changes as the number advances, while the U GB suffix remains. To order the correct replacement, provide the complete code as it appears on the part or on the drawing.

In Argentine industry they appear in gearboxes, pumps, fans, conveyors, road machinery, milling equipment and rolling mill trains. They are also found in the food sector and in aggregate processing plants, where the shaft receives radial load and axial thrust at the same time. Because they are separable, they allow inspection of rollers and raceways without replacing the entire assembly when wear is partial.

To select correctly, you must define the radial and axial load, the rotation speed, the shaft diameter and the type of fit. Mounting is done with a press or controlled heating, never by striking the cage. Lubrication with grease or oil must cover the rollers and raceways, and alignment between the two rows defines the axial clearance. Proper sealing prevents the entry of dust and water, which accelerates raceway wear.

Interchangeability between brands is handled by dimensions and by the series code: a tapered bearing from another manufacturer with the same outer and inner dimensions can be interchanged, but it is advisable to verify the contact angle and the suffix. If you have the part in hand or the code from another brand, send it by WhatsApp to MR Accesorios Industriales and we will quote the equivalent NTN reference or the exact size you need.
