Rigid coupling
Cross & Morse

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. Stresses in both hub and shaft are similar to heavy press fits, however, the actual stresses are easy to calculate; and the hub can always be easily dismantled without damage to it or the shaft; only a torque wrench being required for both assembly and disassembly.
Precision transmission of torque with no backlash is obtained with shaft clamping elements, without the need of tight manufacturing tolerances of mating components. Simplified designs can enable manufacturing cost reductions, coupled with easy assembly and disassembly.

Cross Shaft Clamping Elements provide an alternative method of connecting hubs to shafts to:-
Tapered Bushes, Hydraulic Clamping Systems, Fine-bored Hubs, with Precision keyways & Locking Setscrews ,Heavy Press Fits & Welded Components.
