JM720249 /JM720210 NSK TAPERED ROLLER BEARINGS

NSK  Tapered roller bearings are designed so the apices of the cones formed by the raceways of the cone and cup and the conical rollers all coincide at one point on the
axis of the bearing. When a radial load is imposed, an axial force component occurs;
therefore, it is necessary to use two bearings in opposition or some other multiple arrangement.
