NTN Quatro rolamentos de rolos cônicos

We offer premium tapered roller bearings under the NTN brand names. Most NTN tapered roller bearings feature case-carburized components. Cups, cones, and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability.

In addition to duplex bearings that combine a pair of single row tapered roller bearings, there are also four-row tapered roller bearings composed of two double-row inner rings, one double-row outer ring, and two single-row outer rings. Four-row tapered outer bearings are used in high-load applications such as rolling mill roll necks.
