SIGMA Rolamentos cilíndricos

SIGMA cylindrical roller bearings are ready to meet your needs. We offer standard cylindrical roller bearing sizes and styles, as well as custom bearings. Our dedicated team of engineers will customize bearings for your application. Complete with case-carburizing bearing quality steel and complex geometries, our bearings are designed to consistently perform in demanding situations.

Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface.Cylindrical roller bearings, in which either the inner or outer rings has two ribs and the other ring has one, are capable of taking some axial load in one direction Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.
