SensiFlex® Pneumatic Clutches & Brakes for Tension Control

Design Features & Options Tension control applications are unique. They require a clutch or brake that will operate smoothly throughout the entire converting process without the sticking, pulsing or cogging inherent in some designs. Heat caused by constant slip must be dissipated to prevent friction lining fade and premature unit failure. The clutch or brake must be capable of a broad range of torque output to supply the processing flexibility demanded from today’s converting machinery. One pneumatic clutch and brake line offers these features plus the added benefits of competitive price, simple installation and long, maintenance free service…SensiFlex® from Mach III Clutch, Inc.

SensiFlex® DESIGN FEATURES

Sensitivity = Flexibility
A patented actuator provides maximum sensitivity to the slightest air pressure changes for the broadest possible range of torque output and infinite controllability.

Superior Heat Dissipation
The unique SensiFlex® design pulls cooler, ambient air into the pneumatic clutch or pneumatic brake then pushes it outward through radial holes to effectively dissipate the heat generated by constant slip. Higher thermal horsepower capacity is achieved without the addition of fans or expensive water cooling equipment. Lower operating temperatures reduce the chance of lining fade and increase the wear life of the unit.

Smooth, Low Maintenance Performance
Precision machining assures parallel alignment of the friction and drive surfaces for smooth operation and even wear. A single, specially molded, low coefficient friction disc provides smooth performance and exceptionally long life. All SensiFlex® pneumatic clutches have a dual bearing pilot which provides stability for a field or factory mounted sprocket or pulley, preventing deflection caused by belts or chains.

Simple Installation
Compact, self-contained pneumatic clutches and pneumatic brakes provide easy, slide on the shaft installation with a single air line connection. Each unit is supplied standard with a customer selected bore size & keyway. SensiFlex® clutches are available from the factory with user specified sprockets or pulleys attached for true “out of the box” installation.

EXCEPTIONAL APPLICATION ASSISTANCE & CUSTOMER SERVICE
Mach III’s engineering, design and sales team provides support before, during and after the sale. Application analysis, selection assistance, reliable lead times and quick response to questions or field problems are components of every product manufactured by Mach III Clutch, Inc.

Design Options to Maximize Heat Dissipation

Mach III is the only manufacturer to offer different clutch models designed to maximize heat dissipation based on machine layout requirements. Separate Pilot Input, Shaft Input and Double-Shaft Foot Mount pneumatic clutch configurations insure that the unique cooling sleeve rotates at the speed of the drive input pulling the greatest volume of air possible through the clutch. This cooling feature is also found in the SensiFlex® BK pneumatic brake.

Choose the Style Best Suited To Your Machine Design Requirements:

	SensiFlex® PI - Pilot Input Pneumatic Clutch For applications requiring the clutch to drive the shaft when engaged. Cooling sleeve rotates with the pilot mounted sprocket, pulley or coupling at the speed of the drive input.
	SensiFlex® SI - Shaft Input Pneumatic Clutch For applications requiring the clutch to drive a pilot mounted pulley, sprocket or coupling when engaged. Cooling sleeve rotates with the shaft at the speed of the drive input. Shaft input clutches can also be used as brakes by fixing the pilot to the machine frame or other stationary surface.
	SensiFlex® FM - Foot Mount Pneumatic Clutch For applications requiring input and output shaft connections. Clutch drives output shaft when engaged. Input shaft and cooling sleeve rotate at the speed of the drive input.
	SensiFlex® BK - Shaft Mount Pneumatic Brakes For applications requiring a brake to provide tension on and/or stopping of an unwind shaft. Brake is shaft mounted and includes a flange provided for fixing the stationary member to a machine frame or mounting bracket. Cooling sleeve rotates at speed of unwind shaft.
