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 loads do not act perpendicularly towards the support surface, it may be necessary to use stronger, 10.9 class bolts.
SKF housings can withstand loads resulting from tightening the attachment bolts to the values recommended by bolt manufacturers (table 1). They are valid for oiled, but otherwise untreated thread surfaces. SKF cannot confirm that tightening to the recommended value will provide sufficient anchoring. Make  sure that attachment bolts and a sufficiently strong support can accommodate all occurring loads.
