Airflex CB element assemblies are used as both clutches and brakes in general power transmission service. The primary feature of the CB design and construction is the Airflex torsional resilient principle made possible by the transmission of power through the side walls of the flexible neoprene and cord actuating tube. This flexibility also permits minor shaft misalignment.

Airflex VC element assemblies are designed and built for severe clutching and braking applications on heavy duty equipment. They are unmatched for high starting loads and sustained slippage where heat generated tends to lower efficiency and shorten the operating life of conventional clutches. Their high torque ratings permit use of smaller diameter units which lowers contact velocity on high speed applications. Ventilated construction permits passage of cooling air, to rapidly dissipate heat from the friction shoes. Torque is transmitted from the side plates of the elements through torque bars to the friction shoes.

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, their 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.

Airflex EB element assemblies are used in both clutch and brake service with light starting loads. The EB is similar in design to the CB except that it is an expanding type unit.

Airflex VE elements were specially designed for greater heat dissipation capacity in an expanding type element. Available in a limited number of sizes, they offer all of the type E features.

Airflex E elements are primarily used as slip clutches or tension brakes; however, they can also be used for general power transmission service. Torque is transmitted from the friction shoes to the element housing through torque bars. Engagement occurs when air expands the actuating tube forcing the friction shoes against the inside diameter of the drum. Release springs assist in shoe disengagement and counteract the centrifugal force.

Airflex ER couplings are expanding units with neoprene facing. As such, they combine the advantages of a flexible and disconnect coupling. Engagement of the element should occur when there is no speed differential between driving and driven shaft.

Airflex magnetic clutches and brakes are stationary field, multiple disc units controlled by electromagnetic force. Units are designed to be used in an oil environment, where high speeds and high cyclic rates are encountered.

Model #: SB-400, SB-450, SB-525, SB-525, SB-750, SC-275, SC-325, SC-375, SC-550, SC-650, SC-775

Airflex hydraulic clutches are multiple-disc units available in stationary or rotating cylinder design. They are intended for use with a spray, splash or through the shaft lubricating system; where high speeds are encountered and a high torque/small envelope ratio is required. They are also suitable for air actuation.

Airflex DC clutches and brakes are available in single and multiple disc designs. They feature a favorable torque to size ratio and low inertia friction disc assemblies.

Airflex DBBS disc style brakes are spring-applied and air or hydraulically released. Its torque capacities and heat dissipation characteristics make it ideal for high speed cyclic applications. Equal torque is developed in either direction of rotation.

Airflex DBA disc style brakes are spring-applied and air or hydraulically released. Its torque capacities and heat dissipation characteristics make it ideal for high speed cyclic applications. Equal torque is developed in either direction of rotation.

Airflex DBB disc style brakes are spring-applied and air or hydraulically released. Its torque capacities and heat dissipation characteristics make it ideal for high speed cyclic applications. Equal torque is developed in either direction of rotation.

Danfoss’s passion for developing revolutionary new disc brake technology led to the development of the Floating House Brake (FHB)—a patented braking concept that uses a floating housing instead of a floating rotor. Rated for over 430,000 lb-in of torque, these spring-applied, air-cooled disc brakes are commonly used in applications like surface mining, oilfields and other heavy-duty industrial machinery. The Airflex FHB both maximizes friction life and offers a rapid friction replacement capability.

Airflex DCB combination air-actuated disc clutches and spring-applied disc brakes were specifically designed for the can making industry. It is ideally suited for high speed continuously running machinery requiring an extremely fast stop.

The Airflex CBC unit combines an air actuated disc clutch and spring applied brake into a compact package, which can be readily adapted to new or existing flywheel drives. Designed primarily for high cyclic punch press service, the unit has been applied on a wide variety of high speed, high cyclic applications.

Airflex FSPA packages feature drum type CB or VC air applied clutches fastened to standard bearing-mounted flywheels. These clutch/flywheel assemblies are then combined with drum type CS and CTE or disc type DBA spring-applied, air released brakes. Although designed primarily for punch press use, they have found application on all types of cyclic equipment.

Danfoss Airflex AMCB AccuStop® clutch and brake combinations pack a low-maintenance, high-performance punch. Featuring an air-actuated disc clutch and a spring-applied disc brake, Airflex AMCB AccuStop® units are engineered for small- to medium-tonnage, high-speed, high-cycle punch presses. They deliver high torque and low inertia in a compact design.
