CAB Copper Alloy Brake The Wi ch i ta CAB Copper Alloy Brakes are pneumatically actuated water cooled brakes designed for use in consta n t l y s l i p p i n g applications. The brake has a high power rating within a reduced envelope size for original equipment and upgrading of existing plant. Applications The Copper Alloy Brake benefits various tension control and continuous slipping applications in : Paper, Film & Foil Industry : Unwind stands on laminators, coaters, winders and slitter/rewinders. Steel & non-ferrous strip industry : Decoilers & roller tension units. Marine industry : Anchor handling, cable laying and towing winches. Testing industry : Dynamometers for gear reducers, agricultural tractors, large vehicles and mining mach i n e r y. .. Enclosed for dust protection. The sliding covers together with a solid cover plate on the other side of the brake effectively enclose the brake making it physically safe from foreign objects. The covers also make it more suitable for clean room environ- ments as they effectively contain any friction dust. .. Multi-range torque selection. Although the stan- dard brake has a single annular piston there are optional multiple piston actuators available for multi-range facility. This allows optimum torque selection, giving increased machine flexibility for higher productivity. .. The air inlet is positioned at the side of the cylin- der so that the air supply pipe is close to the face of the machine giving better protection and aes- thetics. Benefits .. Four sizes in either one or two plate models ensure the most suitable brake selection for the application. .. Ease of installation. A novel design of spiral water flow allows better flow integrity within the water jacket. This enables brake mounting with the water connections in any direction; from the top, bottom or side, giving addi- tional flexibility in machine layout and design. The water inlet and outlet connections are located in one area, which reduces the space envelope of the brake. For brakes to be mounted through shaft, the centre of the front cover will be machined out. .. Ease of maintenance. The visual wear indication allows easy wear verification without touching the brake, saving on down time and facilitates better scheduled mainte- nance. No wear adjustment needed, because the long stroke piston allows for full wear life of the friction mate- rial. The removal of just four cap screws in the front of the brake is all that is required to disassemble the brake. After removal of the front cover, all the internal parts slide out. The water jackets slide on four substantial pins and the rotating drive disc slides on gear teeth.

CAB Copper Alloy Brake Performance Water inlet temperature 10° C min. - 50° C max. Max temperature rise across brake = 25° C.If a lower minimum torque is required please consult Wichita. Selection Guide – Service Conditions Torque rating : Dynamic torque ratings may be used in selection for tension control applications. Service factors vary for more arduous applications, but as a general guide, use 75% of brake torque. MR – Multi Range versions of all sizes available. Maximum torque with full complement of MR pistons is approximately 50% of the 5.5 bar rating of the regular brake. Air...
