The advantages of Conex keyless shaft to hub connection

  • Traditional methods of shaft-to-hub connection are not satisfactory in many applications, mostly when frequent start-stopping-reversing are involved. Over the time the keyway engagement became less accurate due to mechanical wear. Conex bridge the clearance between the shaft and the hub and distributes the power transmission over the entire surface while with a key connection the transmission is concentrated on a limited area only. Conex is a zero backlash connection.
  • This allows savings in materials because the shaft diameters can be done smaller, and make Conex ideal for heavy transmissions, with overloads or continuous reversing.
  • 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.
