Cross+morse Shaft Clamping Element - Color: Silver

Cross+Morse is a Birmingham based manufacturer of Power Transmission products and solutions with over 100 years of history right in the centre of the engineering hub in the West Midlands region in the United Kingdom.

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.
