1) Valori esclusi per i cuscinetti assiali orientabili a rulli. Per cuscinetti con lo stesso Ø esterno i valori sono i medesimi sia per cuscinetti a doppio effetto sia a semplice effetto.
1) These value are not valid for axial roller bearings for bearings having the same outer diameter. Value are the same for both double acting and single acting bearings.
