  • Application Considerations: Pneumatic or Electric Brakes & Clu
    What are the main differences between pneumatic brake and clutch assemblies versus electric brake and clutch assemblies? Pneumatic clutches and brakes use air cylinders to actuate and provide the normal force to transmit torque. They require 30-80 PSI of a clean compressed air...
  • Electromagnetic Brakes Let Hospital Rooms Go Ergonomic
    to the patient's head. Ceiling- mounted systems provide additional flexibility, but can require expensive structural reinforcements to the building and leave patients with the uncomfortable image of a mechanical arm hanging over them. The hydraulic or pneumatic brakes used to hold ceiling-mounted systems in place
  • Getting up to speed with wrap-spring clutch/brakes
    within a few thousandths of an inch need highly controllable, precision brakes. Engineers typically spec friction brakes for these applications. But a wrap-spring clutch/brake can also do the job. It combines in a single package a clutch and brake plus an actuator (solenoid or pneumatic cylinder
  • Brake Upgrades Lower Maintenance Costs (.pdf)
    The reliability maintenance team at the fine papers division of a major multinational paper producer recently discovered an alternative to the maintenance and repair aggravation they were experiencing from the pneumatic dual disk brakes on their slitter/sheeter lines and offline paper winders
  • Electropneumatic Cylinders
    , a pneumatic brake, and an electronic controller. Continuous monitoring of rod position and velocity, combined with positive stopping action of the brake, ensures accurate positioning. The system allows up to 32 user-defined set points for each of eight programs. It interfaces to I/O devices such as computers
  • AHTS Tug Ship, Maersk
    a pneumatic to hydraulic pressure intensifier system. The brake system develops brake torque of up to 284 kNm (2,513,600 lbf-in) per shaft.
  • Catamaran Ferry 2, Stena Line
    Each of the two drive shafts is equipped with a 1150 mm (45.3 in) diameter brake disc and eight Dellner Brakes type SKD 80 hydraulically applied disc brakes. The pressure for the brakes is provided by pneumatic to hydraulic pressure intensifiers. Pneumatic pressure of 7 bar (101.5 psi) is increased
  • Hellenic Navy - Gun Boats
    in) or 950 mm (37.4 in) brake discs. The brakes are pressurized with a pneumatic-hydraulic pressure intensifier. Brake torque generated is approx. 200 kNm (1,770,000 lbf-in) depending on disc size and the applied pneumatic pressure. The purpose of the brakes is to quickly stop the propeller to change
  • Case Story- Oil Drilling Rig
    Each brake system consists of a Dellner Brakes type SKD 2x100 hydraulic pressure applied disc brake working on an 1160 mm (45.7 in) diameter disc and a pressure intensifier system. The brakes are actuated with up to 150 bar (2,180 psi). of hydraulic pressure that is generated through a pneumatic
  • Paperboard Web Unwinds with Ease (.pdf)
    an unusually high torque requirement (127,000 in-lbs, or 11,000 ft-lbs), which Dover Flexo Electronics (DFE) was able to meet with a large (thirty-inch diameter), heavy-duty pneumatic tension brake: the new 3000 Series Dual Disc brake. DFE supplied three of these brakes for use on this single unwind
