Air Threading Clutches Provide Consistent, Reliable Tap Depths - Increase Tool Life

The Logan Clutch is fast acting, providing consistent reliable tap depths for small and large diameter taps, from aluminum and brass to stainless steel. Repeatability within an 1/8th of a turn is the rule, not the exception. Since directional speed changes are smooth , the load on the tap is uniform, prolonging the life of the tap. Fewer tool changes are necessary, shaving valuable hours from a big job.

Ideal for Steel and Brass Method Tapping.

Logan Air Threading Clutches provide 200% more torque than standard mechanical clutches, allowing you to utilize either brass or steel method tapping with ease. Thread with confidence.

Air Threading Clutches are Self Adjusting - No Slippage!

Since Logan Air Threading Clutches are self-adjusting, they eliminate the need for your operator to mechanically adjust the threading clutch, providing your machine operator or maintenance person additional time to troubleshoot more complicated manufacturing challenges.

Retrofits Easily with Early and Late Model Davenports

Logan Air Threading clutches have been designed to enable users of early and late model Davenports to easily retrofit their existing machines that currently use mechanical threading with this Logan Air Threading Clutch arrangement.

Air Threading is Available on New Davenport Machines Too!


Improves Quality, Productivity and more...

Logan brings you more than just quality and productivity - Consistency Too!

Think about it; thousands of hours of lost production can be attributed each year to mechanical threading clutches that are over, or under adjusted; forcing you to compromise on part quality and tap life.

Logan Air Threading Clutch engagement and disengagement is so crisp and positive - your tap depth remains consistent over millions of parts - Taps live longer too.

Eliminates Mechanical Linkages

LOGAN CLUTCHES – How They Work
High Torque / Small Envelope

Pressurizing the Logan clutch cylinder-piston assembly forces the piston to clamp and lock the friction and steel separator discs. Torque is transmitted through to the drive cup or clutch gear slots. 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. Logan clutches are self–adjusting. Piston travel increases automatically to accommodate disc wear.

 

LOGAN AIR THREADING® CLUTCHES Simplified Operationair threading davenport

Change of speed is accomplished through a limit switch and a solenoid activated, directional control valve. At the prescribed depth, the limit switch is tripped by a cam or CPU, allowing the tap to back out of the work piece. Low speed for tapping - High speed to back out.

LUBRICATION

Since Logan Air Threading clutches operate at relatively high speeds, a steady metered flow of lubrication is required.


 

EACH AIR THREADING CLUTCH PACKAGE CAN BE FURNISHED COMPLETE WITH AN ELECTRICAL-PNEUMATIC START-UP KITView of Electrical-Pneumatic Start-Up Kit

Each Air Threading Clutch kit comes complete with all of the necessary mechanical, pneumatic and electrical components and schematic drawings necessary to make the switch from mechanical to Logan smooth and efficient.

Field retrofits take little time since the mechanical portion of the kit is designed to fit within the existing mechanical clutch envelope. All that remains is the plumbing of air lines, and the mounting and wiring of a directional control valve, limit switch and bracket. Step-by-step, detailed schematics are furnished with each kit.


HOW TO ORDER:

Specify make or model year of the machine. Provide part number and style of clutch that is being replaced.
