Load carrying capacity
All SDAF housings are intended for loads acting perpendicularly toward the support surface. If the housing is supported over its entire base and the loads are purely perpendicular, loads are limited only by the bearing.
If loads acting in other directions occur, or if the housing is not supported over its entire base, be sure that the magnitude of the load is permissible for the housing and the attachment bolts.
Load carrying capacity of the housingGuideline values for the safe loads of housings made of grey cast iron are listed in the product tables for bearings on an adapter sleeve and for bearings with a cylindrical bore. The safe loads have been calculated using a safety factor of 5 against base fracture and a factor of 2 against cap bolt yield.
For housings made of ductile iron, the values obtained from the product tables should be multiplied by a factor of 1,5 for ASTM A536 grade 65-45-12. For information about ASTM A536 grade 80-60-03, contact the SKF application engineering service. For purely axial loads, static or dynamic, the loads on the housing should not exceed 65% of P180°. For bearings mounted on adapter sleeves, the permissible axial load is dependent on the adapter sleeve.
