Other bearings of the TDI configuration

If no suitable bearing is found in the product tables, it is recommended to look at whether the standard components of the new SKF four-row tapered roller bearings without intermediate ring can be used to "build" a tailored bearing. For example, from the components of the four-row tapered roller bearing BT4-8004 G/HA1 (fig 1) it is possible to combine
  • 2 cups (outer rings) OR-BT4-8004-1/HA2 (1) with
  • 1 double cone (inner ring with two roller and cage assemblies) AJ-BT4-8004 G/HA3 (2)

to form a double row bearings having the dimensions d x D x B = 304,800 x 412,648 x 133,350 mm. This may be advantageous both as regards price and delivery time.
This "building" procedure should primarily be considered if sealed double row bearings are required, although this requires a non-standard inner ring. However, before making the final selection, or in case of doubt, please contact the SKF application engineering service.
