They can bear radial and axial loads in equal measure even at high rotation speeds, guaranteeing precision and rigidity, all thanks to their internal geometry which also makes them easy to handle, being formed by cones and cups which, depending on the type of construction, are alternatively integral with the rotation unit formed by cages and rollers.
They can be:
single row for one-way radial and axial loads and generally mounted and adjusted with a twin arranged specularly;
with two crowns for bidirectional radial and axial loads, generally with pre-established axial play during the production phase used in the most varied sectors of industry;
with four rows of rollers mainly for rolling mills or iron and steel industry for high combined loads, high speeds, highly stressed mechanically and for working environments with high temperatures and the presence of pollutants.
