Constricting Clutches & Brakes

 

Airflex Constricting Clutches & Brakes are drum style products that when pressurized, expand radially inward, forcing their friction shoes against an outer cylindrical drum surface. The rate at which the tube is pressurized determines the rate at which element torque increases. Final tube pressure determines the element torque capacity.

 

Product Sizing

 

Constricting elements are identified by the drum diameter in inches on which they constrict and the width in inches of their friction lining. For instance, a size 26CM475 is designed to constrict on a 26 inch diameter drum and has a friction lining width of 4.75 inches.

CB

 

Airflex CB products are used as both clutches and brakes in general power transmission service. Torsional resilience is provided by transmitting power through the side walls of a flexible neoprene/cord actuating tube. This flexibility also permits minor shaft misalignment.

 

FEATURES:

 

  • The Type CB is suited for high speed, cyclic operations, as well as for coupling and general power transmission.

  • Torque Capacities* Up To: 1,160,000 Ib·in, 131.000 N·m

  • Typical Applications: Can making machinery, commercial laundry equipment, metalforming machinery, oil & gas machinery, printing machinery, rubber processing machinery, tire building machinery

  • Standard Sizes: 3CB150, 4CB200, 5CB200, 6CB200, 8CB250, 10CB300, 12CB350, 14CB400, 16CB500, 18CB500, 20CB500, 22CB500, 24CB500, 26CB525, 28CB525, 30CB525, 32CB525, 36CB525, 40CB525, 45CB525

CM

 

Airflex CM element assemblies were designed primarily for the marine industry for use on diesel driven reverse-reduction gears. In addition to providing all of the CB element features, the CM's ventilated friction shoes permit clutch slippage at low energy rates during vessel maneuvering, as well as cycling engagements at high energy rates. Rim registering allows triple element assemblies.

 

FEATURES:

  • The CM is used in applications where moderate slippage is encountered which would shorten the operating life of a CB element.

  • Torque Capacities* Up To: 3,236,000 Ib·in, 365.000 N·m

  • Typical Applications: Marine propulsion

  • Standard Sizes: 26CM475, 30CM500, 35CM500, 40CM550, 48CM650

VC

 

Airflex VC products are designed and built for severe clutching and braking applications on heavy duty equipment. When compared with conventional clutches they offer:

 

  • Ventilated construction for rapid heat dissipation

  • High starting loads

  • Sustained slippage

  • Improved efficiency

  • Extended operating life

  • Smaller diameters with lower contact velocity

 

FEATURES:

  • The Type VC is specifically designed and built for severe clutch or brake applications in which large inertia loads and sustained slippage would normally result in loss of torque and reduced operating life.

  • Torque Capacities* Up To: 15,189,000 Ib·in, 1.706.629 N·m

  • Typical Applications: Grinding mills, marine propulsion, metalforming machinery, oil & gas machinery

  • Standard Sizes:

    • Narrow Sizes: 11.5VC500, 14VC500, 16VC600, 20VC600, 24VC650, 28VC650, 33VC650, 35VC650, 37VC650, 42VC650

    • Wide Sizes: 12VC1000, 14VC1000, 16VC1000, 20VC1000, 24VC1000, 28VC1000, 32VC1000, 38VC1200, 42VC1200, 46VC1200, 52VC1200, 51VC1600, 60VC1600, 66VC1600, 76VC1600, and 76VC2000
