Torque Coupling with O-Ring/Retainer Pin Connections Enables Quick Socket Changeovers and Prevents Stripped Threads

O-Ring_Connected_Torque CouplingUsed for installing switching mechanisms on railway lines, the drill press to which this torque limiting coupling is attached sinks large screws into railroad ties made of various materials such as steel, concrete, plastic and wood. Each material requires a different size of screw and a different amount of drive torque. The railroad workers are able to manually adjust the slip torque setting of the coupling to the value needed for each material by loosening or tightening the adjustment nut. The output shaft allows for the quick interchange of sockets to accommodate the various screw sizes.

Mach III provides rapid turn-around for application adapted designs. This torque limiter was designed and quoted within 24 hours of the initial discussion between the client and our engineers. The units were manufactured within 3 weeks.

Custom Design Solutions: Clutch with Spider Coupling Adapter

clock July 22, 2014 12:37 by author Mach III Clutch

This clutch is similar to the  58SI  SensiFlex® shaft input tension control clutch.  It has been modified to include a pilot mounted coupling hub which mates with a spider coupling (a.k.a.  jaw coupling).  This clutch is drop-in ready to simplify installation.spider-coupling illustration

Custom Design Solutions: Special C-Face Mounting

clock June 8, 2012 11:57 by author Mach III Clutch

C3C2P-001Mach III designs and manufactures clutches, brakes and torque limiters in custom c-face configurations.  In this example, the customer needed a device to limit the torque between the motor and a coupling which was used to fasten a cap.  The customer required the torque setting to be adjustable.

Mach III suggested an air engaged clutch.  The customer would be able to adjust the torque applied to the capper coupling by increasing or decreasing the air pressure supplied C3C2P-001 001to the clutch.  When the capper met resistance, the clutch would slip.

Unique in this application was the motor face which required that the clutch mounting flanges be off-center from the clutch housing.  The motor and capper coupling were sent to Mach III so the dimensions could be verified.  The second photograph shows the finished clutch in place between the motor and capper coupling.

Nothing Else Compares For Narrow Web Converting

Which is Why Caulder Converting Uses SensiFlex®SensiFlex® Tension Control Clutch Air Flow Illustration

Having founded Caulder Converting (Hendersonville, NC) as a contract converting company, Dennis Caulder knew first hand the frustration of working with clutches and brakes that engaged at too high a pressure and then pulsed or cogged during operation.  He sought to eliminate such problems when his company started manufacturing converting equipment of it’s own.  While searching the web in 2007, he came across Mach III’s SensiFlex® tension control clutches and brakes. Interested by the fact that SensiFlex® was specifically designed for converting applications, he decided to try a 58PI clutch for a press that he was building. Since that time, Caulder Converting has used Mach III clutches and brakes on all of its presses. Caulder Converting Eleven Anvil PressAccording to Dennis, “Nothing else compares for narrow web converting.”

Caulder Converting uses a component-type design allowing them to layout and build each press tailored to their customer’s needs. Their most recent project is the eleven anvil, seven inch press pictured here. Designed to produce a multi-layered medical device, this variable speed press runs from 40 to 50 feet per minute.  The press incorporates a total of twenty two SensiFlex® clutches and brakes including the 58PI shown below.SensiFlex® 58PI Tension Control Clutch

Morse Taper Input Torque Limiter Coupling

clock April 22, 2009 05:59 by author Mach III Clutch

This torque limiter is part of an assembly used to open and close a gate valve.  The Morse taper input connects to a handheld power tool while the female square output connects to a square boss on the valve assembly.  The torque limiter prevents over-tightening the valve.


  • #3 Morse Taper Input Torque Limiter Coupling - Square Output
  • Variable Output Options:  Unit shown has a 2.06 Inch square.  Other geometries available including imperial and metric bores with keyways.
  • Maximum Torque Setting:  1400 pound inches
