| It is a self-centering and non-floating tapered shaft hub in corrosion-protected design with a hexagon nut and a lock nut. The rotational accuracy of the tapered shaft hubs is 0,03 mm. By using tapered shaft hubs, all shaft-hub joints of machine elements such as sprocket wheels, gear wheels, belt pulleys, cams, levers etc. can be easily and efficiently established. Material External part - Stainless steel, nickel-plated
Inner part - Stainless steel, nickel-plated
Nut - Stainless steel, nickel-plated, hardened
Assembly The lock nut at the outer part facilitates locking of the shaft-hub joint if freely rotating shafts are involved. For mounting, a cresent wrench (thickness max. l2-l3) is used. References Comply with mounting instructions, mounting examples, and technical data.
