SITCSection 7
U.S. imports of spherical roller bearings (SITC 74630) totaled $20.8M in April 2026, traded with 39 countries.
Importers of Spherical Roller Bearings paid $3.1M in duties in April 2026 — an effective duty rate of 17% on $17.7M in dutiable value, based on actual customs collections rather than the published tariff schedule. Spherical Roller Bearings imports of $20.8M in April 2026 ran 13% above the year-to-date monthly average of $18.3M.
Last updated: April 2026 dataSpherical roller bearings are self-aligning by design, accommodating shaft misalignment and heavy combined loads in applications such as paper mills, mining conveyors, and large industrial fans. Their barrel-shaped rollers and concave outer raceway distinguish them mechanically — and for classification purposes — from cylindrical and tapered variants. Importers sourcing from origins subject to antidumping orders on roller bearings should verify whether spherical types are within the scope of any active measures.

The defining feature is the self-aligning capability conferred by the spherical (concave) outer raceway, which allows the bearing to accommodate angular misalignment between shaft and housing. This geometry — and the barrel-shaped rollers — distinguishes spherical roller bearings from cylindrical (74650) and tapered (74620) types, each of which occupies a separate SITC heading.
Primary end-use sectors include pulp and paper processing, mining and bulk material handling, heavy industrial fans and blowers, and large gearboxes. These applications share the characteristic of high loads combined with potential shaft deflection or housing misalignment, which is precisely the operating condition spherical roller bearings are designed to tolerate.
