With Logan air threading clutches. engagement and disengagement is so smooth and positive – Tap depth remains consistent over millions of parts. 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. Engagement and disengagement are so smooth and positive – Tap depth remains consistent over millions of parts. Logan Hi-Capacity Air Threading Clutches are simple to install and available for almost every Euroturn ever made.

Simple To Install
Most Logan Air Threading Clutches Utilize existing clutch drive cups, (clutch gears) and shafts
Hi-Capacity Air Threading
Cut-away view of a Logan Hi-Capacity Air Threading Clutch. Utilizes existing drive cups, (clutch gears) and shaft. Fits within existing old-style mechanical clutch envelope and transmits 85% more torque.
Direct Air Connection No linkages
Utilizes existing clutch gears in most cases
Gain speed and cycle time by running larger tapping jobs on smaller machines
Logan Air Threading for your Euroturn
Logan Clutches – How They Work
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.
Electrical-Pneumatic Start up kits
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.
Simple to Install
Easily Retrofits with early and late model Acmes
Field Installation Service is also available
Here’s How to Order
Call Logan and specify machine make and model. Provide part number and brand of clutch being replaced.
If necessary, confirm bore, keyway, and axial length of clutch.
