    Clutches

    Clutches

    Multiple or single-position tooth clutches are positive engagement devices having open or nickel-plated, enclosed housings. Tooth clutch designs include a pilot-mount version (accepts sprockets or couplings), a flange-mount version that connects to bearing-supported devices and integral sprocket versions. Air-engaged tooth clutches produce up to 60,000 in-lbs. torque. Spring engaged tooth clutches, with up to 72,000 in-lbs. torque, are the ultimate holding device. Single and double-flex couplings, specifically designed for high-torque tooth clutches, are used for inline shaft connections.

    Friction Clutches

    Friction Clutches

    Nexen’s single-disc, self-adjusting Clutches mount on a driving or driven shaft. They cover transmitted horsepower ratings from fractional to 25 hp, torque ratings to 5000 in-lb with thermal capacities to 2.5 thermal horsepower, and maximum operating speeds to 3600 rpm. Most are available in Sheave, Pilot, or Coupling Mount versions.

    Tooth Clutches

    Tooth Clutches

    Available in a variety of Single or Multiple Position Models, as well as a Sprocket Tooth design, there are Standard and Metric Models available. Most can be used with a Single or Double Flex Coupling Assembly for in-line coupling applications.

    Friction Brakes

    Friction Brakes

    Friction brakes have a stationary pad (friction facing) and a rotating wear surface. Common configurations include drum brakes, caliper disc brakes and shaft-mounted brakes with an integral disc and rotor. Friction brakes provide controlled deceleration, stopping, holding, and tension control. Air and spring-engaged versions are available in all brake configurations.

    Rotary Brakes

    Rotary Brakes

    Air or spring-engaged, shaft-mounted friction brakes come with tapered bores to accept QD bushings or straight, bored and keyed-to-size disc hubs. Bushings are available to reduce the size of the standard, straight-bore models. Air-engaged brakes are used for stopping, holding, controlled deceleration, and tension control. Spring-engaged brakes are excellent stopping and holding devices. Multiple sizes provide torque up to 10,000 in-lbs.

    Drum Brakes

    Drum Brakes

    Nexen's drum brakes are actuated with a diaphragm-sealed actuator that forces a brake shoe on a drum surface to provide the braking torque. Brake drums are bored and keyed to fit standard shafts. The brake shoes are clamped on the outside of the drum to provide brake torque up to 3750 in-lbs. Hinge top models offer a convenient feature to change rolls when the brake is used in tension control applications.

    Caliper Brakes

    Caliper Brakes

    Caliper brakes are used in controlled deceleration, cyclic stopping, holding, emergency stops, and tension control applications. Nexen offers a wide variety of caliper brake designs, including air actuated/spring-released, spring engaged/air-released, and spring engaged/hydraulic-released models. Several disc diameters up to 24-inches are offered to provide torque up to 50,000 in-lbs. Multiple calipers can be used on a single disc to increase torque and accommodate various disc thicknesses. 

    Friction Clutch-Brakes

    Friction Clutch-Brakes

    Nexen’s Friction Clutch-Brakes combines the features of a Friction Clutch with a Friction Brake into a single unit. Standard models offer pilot mount, sheave mount and pilot mount with coupling half options. Pilot Mount units are available in various standard bores sizes with customization possible with bushings and couplings.

Standard models offer pilot mount, sheave mount and pilot mount with coupling half options. Pilot Mount units are available in various standard bores sizes with customization possible with bushings and couplings.

    Friction Clutch-Brakes

    Friction Clutch-Brakes

    Conveniently packaged clutches and brakes for a start and stop applications. Clutch-brake combinations have mounting features that make them adaptable to NEMA and IEC motor frames. All clutch-brakes operate on static air pressure.

    Torque Limiters

    Torque Limiters

    A torque limiter protects mechanical equipment or its work from damage by mechanical overload. A torque limiter may limit the torque by slipping a friction plate clutch or disconnecting the load entirely. The action of a torque limiter is useful to limit any damage to the machine or product due to mechanical failures or product jams in the machine and is typically installed on the output side of gear reducers to protect the gear set. 

    Pneumatic Torque Limiters

    Pneumatic Torque Limiters

    Nexen’s pneumatically engaged, single-position torque limiters are the best overload protection devices available. The “TL” Series units are ball/detent clutches equipped with overload sensors.

    Mechanical Torque Limiters

    Mechanical Torque Limiters

    Nexen’s Torque Limiters protect the drive and driven components from damage associated with torque overloads caused by material jams, operator error, or various unforeseen reasons that pose a significant threat to machine downtime.

    Tension Control

    Tension Control

    Precise tension control is vital to any web or strip-fed operation, and the product must be fed under tension, processed under tension and wound up again under tension. Tension controllers are an integral part of maintaining this set tension. Nexen tension controllers range from simple systems with diameter feedback (open loop) to dancer control systems and the highest precision systems using web tension sensor feedback (closed loop).

    Tension Control Brakes

    Tension Control Brakes

    Nexen’s Tension Control brakes offer precise control over the full operating range – from the high torque needed to manage a large roll, to the lower torque requirements for more delicate materials and demanding applications.

    Tension Control Clutches

    Tension Control Clutches

    Nexen's line of Modular Tension Control Clutches is designed to be the most flexible, maintenance-free pneumatic units available for continuous winding operations. Ruggedly built to endure the continuous drag and high heat load that tension control demands, yet extremely sensitive and responsive to a wide range of torque requirements.

    Web Controls

    Web Controls

    Nexen’s Web Controllers are a closed-loop, load cell-based tension control products which use torque to control the tension of paper, film, foil, or fabric in all zones of web processing machines.
