NTN Bearings

NTN tapered roller bearings are built to carry both radial and axial loads at the same time. The angled rollers make line contact with the raceways, which gives the bearing high load capacity and good rigidity. You will find them in gearboxes, wheel hubs, and many types of industrial equipment where precision matters.

Double row tapered roller bearings from NTN handle radial and axial loads in both directions, providing high load capacity and rigidity. They suit gearboxes, machine tool spindles and mining equipment, where precision and durability matter. We quote these bearings by part number or dimensions to match your application.

The E-CRO-… designation covers double row tapered roller bearings from NTN. In this code, the E prefix points to a special design, CRO marks the tapered roller series, and the numbers that follow—such as E-CRO-2418 or E-CRO-3664—set the size and specific dimensions of each bearing. Choosing the right one starts with knowing the bore, outside diameter, and width your equipment requires, along with the load and speed conditions it will face.

When a shaft has to carry radial and axial force at the same time, an angular contact ball bearing is often the right answer. The raceways sit offset from each other, so the balls meet them at an angle instead of straight on. That geometry gives the bearing more capacity for thrust than a deep groove ball bearing of the same size. Machine tool spindles, pumps, compressors and gearboxes are the usual homes for this design, where precision and rigidity matter. MR Industrial Accessories supplies the NTN line to maintenance and purchasing teams in the United States and Latin America.

For equipment that must handle radial and axial forces simultaneously in a single direction, the NTN B series angular contact ball bearing is a single-row solution with offset raceways.
