SKF Cooper split roller bearings and bearing units

Loads The permissible radial load of a flanged housing is typically: • 26% of the bearing static load rating (C 0 ) when using 01 or 02 series split cylindrical roller bearings • 20% of the bearing static load rating (C 0 ) when using 01E, 02E, and 100 series split cylindrical roller bearings For 03/03E series split cylindrical roller bearings, as well as split tapered roller bear- ings, contact SKF. The permissible axial load of a flanged housing is typically: • 18% of the bearing axial load rating (C a ) when using 100 series split cylindrical roller bearings • 25% of the bearing axial load rating (C a ) when using 01 or 02 series split cylindrical roller bearings • 13% of the bearing axial load rating (C a ) when using 01E or 02E series split cylin- drical roller bearings For 03/03E series split cylindrical roller bearings, as well as split tapered roller bear- ings, contact SKF. Depending on the load direction, higher load carrying capacities may be possible with modified designs and alternative materials. Design considerations To maximize bearing service life and prevent deformation of the housing bore, SKF rec- ommends the mounting surface (bulkhead or support plate) has: • a flatness to tolerance grade IT7, in accordance with ISO 1101 • a surface roughness Ra ≤ 12,5 µm Square flanges are more appropriate for steel frames or skid mounted units. Centring recesses The housings are supplied with a centring recess, which can be used to centre the housing on a shoulder, guide ring, or spigot. Dimensions for the recess are provided in the product table, page 150 . The recess is designed to suit a spigot diameter machining tolerance of f8. Design considerations 149 5
