SensiFlex® Tension Control Clutches & Brakes


Air Engaged Friction Clutches & Brakes For Tension Control Applications

SensiFlex® Application

SensiFlex® clutches and brakes are designed for one purpose – tension control. They are not standard clutches and brakes that have been repurposed for tension control by substituting a low coefficient friction pad. SensiFlex® clutches and brakes engage at low pressures and are capable of a broad range of torque output. They supply the processing flexibility demanded from today’s narrow web converting machinery without sticking, pulsing or cogging.

SensiFlex® Options

SensiFlex® clutches and brakes dissipate heat most effectively when the cooling sleeve rotates at the speed of the drive input. Choose the style best suited to your machine design or retrofit requirements.

SensiFlex Design Options

SensiFlex® PI Clutch

SensiFlex PI Clutch

Pilot mounted sprocket, pulley or coupling is input, clutch drives shaft when engaged.

SensiFlex® SI Clutch

SensiFlex SI Clutch

Shaft is input, clutch drives pilot mounted sprocket, pulley or coupling when engaged.

SensiFlex® FM Clutch

SensiFlex FM Clutch

Input shaft drives output shaft when clutch is engaged.

SensiFlex® BK Brake

SensiFlex BK Brake

Provides tension on and stopping of the unwind shaft.

SensiFlex® Features

  • LOW PRESSURE ENGAGEMENT & CONTROLLABILITY
    Exclusive, patented actuator engages smoothly at low pressures and provides maximum sensitivity to slight changes in air pressure for infinite control of torque output.
  • SUPERIOR HEAT DISSIPATION
    Radial cooling holes pull cooler, ambient air through the clutch or brake to dissipate the heat generated by constant slip, preventing friction lining fade and premature wear.
  • SMOOTH OPERATION
    Smoothness is assured through precision machined components, a single friction surface and a dual bearing pilot that minimizes deflection.
  • SIMPLE INSTALLATION & LOW MAINTENANCE
    Each unit is supplied with a customer selected bore size and keyway for simple, slide-on-the-shaft installation with a single air line connection. Requires no maintenance until friction lining is worn, which is easily replaced in the field.

SensiFlex® Quality

  • Precision machined components made from solid bar stock – no castings used
  • Each SensiFlex® clutch and brake unit is individually tested for smoothness prior to shipment
