    = buckling force, kN. Fb = buckling force bearing factor. Another factor to consider is the motor size. A motor is selected by calculating the required torque as a function of load on the system and lead of the roller screw and comparing it to available motors and power transmission components
  • CD(R) Couplings Provide Needed Misalignment Capability in New Tri-Turn, Multi-Spindle Screw Machine Operating at 5000 RPM; Heat and Vibration Eliminated
    with a corresponding counter-spindle assembly, a Zero-Max CD model 6A45C Coupling is employed. Each counter spindle connects via the coupling to a splined shaft, which connects to a 7-1/2 HP spindle motor powering each counter-spindle. Tri-Turn Multispindle screw machine utilizes Zero-Max CD couplings
