Also, the load on your tap is uniform, prolonging the life of the tap. Fewer tool changes are necessary, shaving valuable hours from a big job. Logan also provides up to 200% more torque for heavy-duty pipe thread tapping.Also, the load on your tap is uniform, prolonging the life of the tap.

Logan Hi-Capacity AirTM Threading Clutches are simple to install and available for almost every Acme ever manufactured.
Pressurizing the cylinder forces the piston to clamp and lock the friction and steel separator discs. When pressure is removed, release springs separate the separator discs and maintain a running clearance between separator and friction discs.
The amount of pressure controls the amount of torque.
Change of speed in threading applications is accomplished through a limit switch and a solenoid-activated, directional control valve. At the prescribed depth, the limit switch is tripped by the threading slide shaft, signaling the threading clutch to change speeds. Low speed for tapping - Fast speed to back the tap out. (Left hand threading applications require the inverse sequence).
Since Logan Clutches operate at relatively high speeds, a steady metered flow of lubrication is required over the bearing and disc pack surfaces.
Each Logan electrical – pneumatic start-up kit is designed to save you time and money during Installation. Kits are furnished with detailed schematics to simplify Installation.
Start-Up Kit Includes Valve Assembly, Pressure Gauge, Pressure Regulator, Limit Switch, Quick Exhaust Valves, Fittings, Bracket, Hose and Schematics.
In addition to our line of air/fluid actuated Clutches and Brakes, Logan manufactures and stocks a wide variety of friction-faced and high-carbon steel clutch discs for use in a variety of applications.

Year after year, lost production hours are attributed to mechanical threading clutches that are over or under-adjusted on your Acme-Gridley screw machine - forcing you to compromise on part quality and tap life.
Now, you can achieve state-of-the-art tapping repeatability, reliability, and quality with Logan Hi-Capacity Air Threading® Clutches. Engagement and disengagement are so smooth and positive - Tap depth remains consistent over millions of parts.
