Double row full complement cylindrical roller bearings

Double row full complement cylindrical roller bearings feature solid inner and outer rings, as well as rolling elements properly guided between ribs. Due to their cageless design, they can host a larger number of rollers, which leads to higher load rating values. On the other side, they allow a maximum rotating speed lower than that of the caged design. Available in non-locating, semi-locating and locating design, these bearings represent the proper technical solution in several fields and applications.
