Other SKF double row cylindrical roller bearings

"Tailored" double row cylindrical roller bearings

If none of the bearings shown in the tables is suitable, it is recommended that reference be made to the SKF four-row cylindrical roller bearings to see whether it is possible to assemble a tailored double row bearing from the standard components of the four-row bearings. For example, a combination of the following components of the four-row bearing 319320 (fig 1)
  • 1 inner ring IR-319320 (1)
  • 1 outer ring OR-319320 (2)
  • 2 roller and cage assemblies AR-319320 (3)
  • 2 flange rings WG-319320 (4)
will give a double row bearing having the dimensions d × D × B = 480 × 680 × 210 mm. Such combinations may be advantageous in many cases from a price and availability point of view.
Bearing pairs of matched standard single row cylindrical roller bearings (fig 2) may also offer cost-favourable alternatives.With matched bearings, the bore and outside diameters as well as the radial internal clearance are matched in order to guarantee an even distribution of load. SKF matched pairs of single row bearings are identified by the designation suffix DR, e.g. NU 1076 MA/DR.
In case of doubt and before finalising bearing or bearing component selection it is advisable to consult the SKF application engineering service.
