  • Simplifies Machine Set-up
  • Set-up personnel can position tools closer to the work piece, and reduce dwell time due to repeatable high and low-speed clutch engagement.
  • Guaranteed Cycle
  • Time Repeatability


We replace your 1940s vintage mechanically actuated high-speed and feed clutches, roll clutch, band brake, linkages, pins and lever arms with air-actuated, Self-AdjustingTM Logan clutches. By making the switch from mechanical to Logan, you'll increase your machines, daily and weekly output significantly, through consistent and accurate speed changes and decreased maintenance.

Even better - Our quick-stop power-applied brake prevents coasting and provides accurate braking for bar loader positioning during feed-out.

Power applied brake! Ideal for bar loaders or for manual stock positioning
