RESS A
Spring washers for unsplined shafts

Spring washers RESS A are recommended on smooth shafts without grooves, made of soft material with resistance 589-687 N/mm².
Their use is not recommended on shafts with grinded, hardened or galvanized surfaces, as they would considerably reduce the load bearing.
