SKF/Global Indexing Roller Units - 316977 C 143510007

SKF indexing roller units are basically double row full complement cylindrical roller bearings (fig 1). In a few cases they are based on four-row full complement cylindrical roller bearings (fig 2). The very thick-walled outer ring has three integral flanges. The highly wear-resistant outside diameter is cylindrical, being relieved towards the side faces, or the transition takes the form of a chamfer. The inner ring is in two halves, each of which has an integral flange, which is designed to enable the units to carry heavy axial loads in addition to radial loads. O-rings inserted in a groove in the inner ring flange shoulders prevent contaminants from entering the bearing and lubricating grease from escaping; they also make the bearing a non-separable unit.
