Clamping device are used to minimize the distortion during the machining process. Once the workpiece is located, it is necessary to hold it against the machining force. The mechanism used for this is known clamps. They are work holding devices usually positioned above the supporting surfaces. A locking device is a mechanical component that prevents mated shafts and other machine elements from moving out of position when subjected to external forces. Operating conditions such as initial installation error, temperature variations, vibration and others can all cause issues. These are critical components.

Shaft Clamping Element
Cross Shaft Clamping Elements, by means of frictional forces, provide connection of all types of transmission equipment to their respective shafts, enabling transmission of both torque and axial thrust loads. Precision tapered thrust cones within the clamping elements create high pressure between shaft and hub to securely fasten pulleys, sprockets, gears, etc.
Clamping Elements Type RCK 15/13/16
Designed for use with standardised ranges of pulleys, sprockets, and gears, the shaft clamping elements can accommodate a large range of shaft diameters with a hub of constant bore diameter. On clamping precise axial and radial positioning is provided, combined with medium torque transmission capability.
Clamping Elements Type RCK 13
Designed for use with standardised ranges of pulleys, sprockets, and gears, the shaft clamping elements can accommodate a large range of shaft diameters with a hub of constant bore diameter. On clamping precise axial and radial positioning is provided, combined with medium torque transmission capability.
Clamping Elements Type RCK 15
These shaft clamping elements are very compact units capable of transmitting medium torques. Their design ensures good concentricity between hubs and shafts, without any other means of location. A slight axial movement between hub and shaft occurs during clamping. These units can be installed totally within the hub providing optimum safety, and minimal axial length.
Clamping Elements Type RCK 16
These clamping elements are basically to same design as RCK 13, but with increased diameter flange to locate hub and prevent axial movements, so combining good concentricity with positive axial location. The increase in friction between the cones due to axial restriction results in torque reduction of approx 20%, but this also means reduced surface pressures to both hub and shaft.
Clamping Elements Type RCK 70/71: High Torque Units
Clamping Elements Type RCK 70
These shaft clamping elements are designed to give optimum concentricity, both radically and axially. Similar in design to the RCK 13, 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.
Clamping Elements Type RCK 71
The RCK 71 is a type RCK 70 with addition of a distance ring to prevent axial movement of the hub during clamping. Due to the additional friction between the element and hub during clamping maximum torques are reduced, but with reduction in surface pressures also. This design can be mounted within the confines of a hub providing a stepped bore is provided to accommodate the flange.
Clamping Elements Type RCK 80 / ACE 81
Clamping Elements Type RCK 80
Available for shaft diameters down to 6mm, these shaft clamping elements are designed to fit into small diameter hubs, being particularly suited to light duty, light torque applications. A spacer ring prevents axial movement during clamping; and design ensures good levels of concentricity.

Product Range
Locking Assemblies
For over 25 years they have been manufacturing clamping elements in their own manufacturing plants in Italy. They offer a very wide selection of standard products, and specific tailored products on request. The largest worldwide range of Clamping Elements and Shrink Discs available at all times.
Conex reduces the machining costs, eliminates all the operations for axial fixing of the hub and to machine the keyway seats. This cost benefit can increase dramatically for small production batches.
The shaft diameter can be made smaller which accounts for further savings in materials and makes Conex ideal for heavy transmissions, overloads or continuous reversing.
Couplings
Discover the full range of Compomac couplings:
1. Flexsteel Disc Pack Couplings- Flexsteel is a zero backlash coupling which uses a disc pack made of stainless steel as a drive element, torsionally stiff, but axially and angulary flexible, to compensate for shafts misalignments. A sigle disc pack can compensate for angular and axial misalignments. Two disc packs can compensate for radial, angular and axial misalignments.
2. Metalflex-Servo couplings - Zero backlash couplings – high torsional stiffness- low inertia couplings - Metalflex is an innovative coupling for high performance applications, requiring repeatability, accuracy in positioning, motion and synchronization control at high speed. Metalflex is an assembly of two aluminium clamping hubs with a thin-walled stainless steel bellow, which remains stiff under torsional load, but is axially, radially and angularly flexible in order to compensate for misalignments within the connecting shafts: the result is a zero backlash, high torsional, stiffness, low inertia coupling.
3. CROWNGEAR Steel gear couplings - Crowngear is a double joint coupling manufactured from forged steel using as transmission element two crowned tooth geared hubs which engage two internal straight teeth flanges.
4. COMPOLASTIC Flexible couplings - Compolastic is a range of couplings made of two G25 cast iron, toothed hubs, precision machined, whose teeth work only at compression against an elastic element. Compolastic ensures a safe drive under any conditions, it absorbs torsional vibrations and compensates important axial, angular and radial misalignments of the shafts to be connected. Compolastic can be used at a temperature range of -30°C to +80°C.
5. COMPOGEAR Nylon gear coupling - Compogear is a range of couplings made of two steel, crowned teeth hubs, which are connected with a polyamide internally toothed sleeve. Compogear is resistant to all types of lubricants and hydraulic fluids and can be used at a temperature range of -25°C +80°C.
Torque Limiters
The torque limiter acts as overload protection in machines using gears, pulleys or couplings. Using a torque limiter you have a complete operational safety in machines subject to overloads. High repetitive disengagement and re-engagement accuracy is easily achieved, together with long service life. No maintenance required.
MRF – Modular Rota-Free Torque limiter
Modular Rota-Free has been specifically designed for overload protection in heavy duty, high speed, and high inertia machines, to disconnect immediately the driven side from the motor side, which rotates after disconnection completely free.
