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 or is particularly heavy, 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 will provide sufficient anchoring. Make sure that attachment bolts, dowels or stops, and a sufficiently strong support can accommodate all occurring loads.
