Shaftlock Cone Clamping Elements
RCK70 Cone clamping elements are designed to give optimum concentricity, both radically and axially. Similar in design to the RCK13, but with increased length to provide improved support, and reduced pressures on both shaft and hub. These units must always be installed inside the hub to ensure optimum concentricity. Axial movement of hub will occur during clamping operation.
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), the bore needs to be plain rather than being keyed or tapped and tapered. The second advantage is that the cone clamp acts as an overload protector, with excessive loading causing the clamp to spin on the shaft.

To Install
1 Ensure the hub and shaft surfaces are clean and degreased.
2 Apply a thin coating of light machine oil to screw threads and conical surfaces (do not use any molybdenum disulphide based or E.P. oils).
3 Loosely assemble the clamping element into the required position and tighten the clamping screws in diagonal sequence to the requisite torque, Ts.
4 If the application is subject to corrosive environmental conditions, apply grease to protect screw heads etc.
To Remove
1 Loosen all of the clamping screws in the same diagonal sequence as assembly.
2 The clamping element should now self release.
3 If necessary, tap the screws lightly with a soft hammer.
4 If the clamping element tapers still don't release, remove some of the bolts and insert them into threaded removal holes.
5 Tighten them sequentially to break the clamping ring cone tapers.
6 Lubricate all screws with a light machine oil for the future use of the Challenge Cone Clamping Element.
