SKF single row high-capacity cylindrical roller bearings have the very high load carrying capacity of full complement bearings and the high speed capability of bearings with a cage. They are designed for applications such as industrial gearboxes, wind turbine gearboxes and mining equipment. Their internal design enables the bearings to accommodate axial displacement in one direction. The bearings are of non-separable design.
