Attachment bolt recommendations
In typical applications, 8.8 class hexagon head bolts in accordance with ISO 4014:2011 can be used together with washers in accordance with ISO 7089:2000 or 7090:2000. 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 (table 1). 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, stops, and a sufficiently strong support can accommodate all occurring loads.
