RESS J
Spring washers for unsplined bores

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