• standard clamping hubs with stainless steel screws A4/80 without EASY-pin – mind reduced actuation torques
• versions with longer metal bellows or special hubs are possible on customer request
• check transmission torques of hub-shaft connection for diameters below Dmin
• optional: screws of property class 12.9 for hugher clamping forces or torques, see values in brackets
