SKF Cooper split roller bearings and bearing units

Split cylindrical roller bearings are designed to accommodate radial loads and are availa- ble either with or without outer ring flanges to fit different arrangements. Designs and variants SKF supplies split cylindrical roller bearings in two designs. They are manufactured as: d • locating bearings ( fig. 1 ) • non-locating bearings ( fig. 2 ) Locating bearings • have a split outer ring with integral flanges • have a split inner ring clamped to the shaft with clamping rings • have a split roller and cage assembly • can withstand both radial and axial loads • provide axial location • are also known as fixed type bearings • are identified by the designation suffix GR Non-locating bearings • have a split outer ring without flanges • have a split inner ring clamped to the shaft with clamping rings • have a split roller and cage assembly • can withstand radial loads only • can accommodate axial displacement when expansion or contraction occurs (offers virtually no resistance to axial movement as the rollers spiral through the outer ring raceway) • are also known as expansion type bearings • are identified by the designation suffix EX Fig. 1 Locating bearings Fig. 2 Non-locating bearings D design C design D design C design Table 1 Standard assortment − split cylindrical roller bearings Bearing series Shaft diameter, d a Locating bearings in the Non-locating bearings in the D design C design D design C design – mm/ in. 100 all sizes − all sizes − 01/01E ≤ 300 / 12 > 300 / 12 ≤ 300 / 12 > 300 / 12 02/02E ≤ 300 / 12 > 300 / 12 ≤ 300 / 12 > 300 / 12 03/03E ≤ 155 / 6 > 155 / 6 ≤ 155 / 6 > 155 / 6 2 Split cylindrical roller bearings 70
