In the majority of the applications Mach III encounters our product connects to a round, keyed shaft. This application, however, connects two square shafts. Used on military equipment that is exposed to the elements, all of the metal components are stainless steel. The torque limiter portion (top photo) fits a 1.0 Inch Square, the coupling portion (bottom photo) fits a 0.75 Inch Square. The torque limiter protects the driven shaft by slipping if the factory torque setting of 1,800 pound inches is exceeded.

If your design includes square or other atypical shafting, contact Mach III to explore a custom design solution. All Mach III products are made in the USA and lead times for custom designs average only one week longer than for similar sized catalog products.

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.

For a laminating machine, the customer required Mach III’s catalog model 58PI SensiFlex tension control clutch. However, the machine design called for a 44 tooth, 5M belt pulley that was too small in diameter to be mount on the clutch’s 2.75 inch diameter pilot. The solution to this dilemma is a custom adapter including a P44-5M-25 pulley that bolts to the 58PI pilot. The set screws which fix the clutch to the shaft are accessed through a hole in the adapter.

Mach 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 to 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.

Mach III modifies catalog product designs to accommodate special environments.  In the example below, a torque limiter (slip clutch) was needed to drive a component which pulls food product through processing machinery.  The unit had to be wash down compatible and meet food safety standards.  Mach III designed and manufactured a stainless steel, sealed torque limiter.

Catalog Model:  T4B2H-STL

• Double Disc, Mechanical Friction Torque Limiter
• Torque Capacity: 2029 pound inches @ 50% spring compression
• Output/Input device (pulley, sprocket, sheave) mounts on Pilot
• Open construction with steel drive hub and aluminum housing
• Torque set at factory or in the field through simple nut adjustment
• Bore Size:  Any size specified by customer to 1.25 Inch Maximum with Standard Keyway
• Lead Time:  2 Weeks

Custom Model:  T4B2H-003

• Double Disc, Mechanical Friction Torque Limiter
• Torque Capacity: 2029 pound inches @ 50% spring compression

Which is Why Caulder Converting Uses SensiFlex®

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. According 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.
