This torque limiter is used as a tension brake. The operator uses the knurled adjustment knob to vary the tension on a roll of film as it is unwound and applied to an architectural panel. The unit is constructed on a solid drive hub that extends from the unit and has a half inch wide and deep slot output to accommodate the tang on the core chuck.
Other configurations of this design are possible so if on-the-fly adjustment would be a benefit in your application, contact our factory based engineering and design team. All Mach III products are made in the USA and lead times for custom designs average less than 4 weeks.

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.
Would a custom design make your assembly process easier? Mach III supplies custom adapters and couplings for many catalog models.
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 fit 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 has the capability to supply custom adapters and couplings for many catalog models.
The brake pictured is designed for a machine that requires a slip brake to maintain tension on spool of transformer wire but has a very narrow envelope in which to accommodate it.
- Torque Capacity: 575 Pound Inches @ 80 PSI
- Overall Length: 1.74 Inches, Outside Diameter: 7.25 Inches
- Bore Size: 1.5 Inches
- Vented top plate dissipates heat generated by constant slip.

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.
