Attachment bolt recommendations
In typical applications, 8.8 class hexagon head bolts, in accordance with ISO 4014:2011, can be used together with washers. If the load does not act perpendicularly toward the base, it may be necessary to use stronger 10.9 class bolts.
SKF housings can withstand loads resulting from tightening the attachment bolts to the torque values recommended by bolt manufacturers (product tables for bearings on an adapter sleeve and for bearings on a cylindrical seat). They are valid for oiled, but otherwise untreated thread surfaces. SKF cannot guarantee that tightening to the recommended value provides sufficient anchoring. Make sure that attachment bolts, dowels or stops, and a sufficiently strong support can accommodate all occurring loads.
