The design of these shaft hub connection Recca07 is basically the same as Recca 05, but with an increased flange diameter to position the hub and prevent axial movement, thus combining good concentricity and positive axial positioning. The increased friction between the cones due to the axial limitation reduces the torque by about 20%, but this also means that the surface stress of the shaft and hub is reduced.

Recca shaft hub connection offers the latest in transmission connection technology.
Recca Keyless Locking assemblies connect all types of drives to their respective shafts by means of frictional forces for torque and axial thrust load transmission. Precision tapered thrust cones within the clamping element create high pressure between the shaft and hub to securely hold pulleys, sprockets, gears, etc. The stresses on the hub and shaft are similar to a heavy pressure fit, but the actual stresses are easy to calculate, and the hub can always be easily removed without a damage to the shaft. All you need for assembly and disassembly is a torque wrench.
The shaft clamping element allows backlash-free precision torque transmission without the need for strict manufacturing tolerances of the mating parts. The simplified design results in reduced manufacturing costs and is easy to assemble and disassemble.
