• 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 higher clamping forces or torques, see values in brackets

order example:
KG – VA 180/4W  D1 = 32 G7 D2 = 35 G7 stainless steel screws
KG – VA 30/2W  D1 = 16 G7 D2 = 19 G7 screws – 12.9 – coated
