RCK40-170x225 Challenge Cone Clamping Element 170x225mm Tags Hub Diameter B: 100mmShaftlock Cone Clamping Elements Cone clamping elements are a purely friction method of clamping components to a shaft. The internal components within a cone clamp operate on a taper, so as the cone clamp is tightened the internal diameter decreases while the outside diameter increases. This change in diameters creates the clamping force. There are two main advantages of cone clamps. The first is that for machining your component (i. e. a sprocket),
