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. SKF housings can withstand loads resulting from tightening the attachment bolts to the torque values recommended by bolt manufacturers (→ product table). They are valid for oiled, but otherwise untreated, thread surfaces.

If the bearing arrangement is subjected to heavy radial loads, it may be necessary to use stronger, 10.9 class bolts.
SKF cannot guarantee that tightening to the recommended value will provide sufficient anchoring. Make sure that attachment bolts, dowels or stops, shoulder or guide ring can accommodate all occurring loads.
