Thanks to the large force available for actuationand the use of the steel/sinter combination,which has very low wear characteristics, hydraulically actuated Ortlinghaus Sinus®

multi-plate clutches, brakes and clutch/brakecombined units are suitable for a range ofapplications in mechanical engineering, motorvehicles and transmission systems.The cooling oil, which is led through the platesin a precise manner, allows the heat, whichvaries depending on the particular application,to be dissipated efficiently.To a very large extent these clutches and brakesare wear free and require no maintenance!

Clutch/brake combined units for wet-running1/2 Series 0023 and 0123

Clutch/brake combined units are recognised asbeing safe and reliable for driving presses,metal-forming and machine tools, shears andsimilar machines. They conform with the wellknown safety requirements as laid down in therelevant EC directives.The torque transmitting capability and theswitching capacity can be influenced over a widerange, by the correct selection of the number offriction surfaces.The heat generated from a particular applicationcan be dissipated efficiently with the aid of acarefully designed cooling oil system.The shaft hub connection is with a doublekeyway in the case of series 0023; in the case ofseries 0123, either a double keyway or a lockingassemble can be selected.Friction combinations: Steel/sinter liningsOperating pressure: 60 bar.Pressure and cooling oil intake: Via rotary inletthrough the shaft.Application: In stamping, embossing anddrawing presses, in automobile body presses,shears and similar machines.

Sinus® multi-plate clutches forwet-running, standard version3 Series 0021-007

This version can be put to use universally as acompact machine transmission clutch.Friction combination: Steel/sinter liningOperation pressure: 18 to 20 barPressure and cooling oil intake: Via rotary inletthrough the shaft.Examples of application: In transmissions formachines and vehicles, stationary and mobilecranes, other lifting devices.

Sinus® multi-plate clutches forwet-running; version for high torques4 Series 0021-3.3

A clutch for heavy-duty drives; normal versionwith shoulder housing and without “emergencyengagement facility“. A version with“emergency engagement facility“ is alsoavailable.Large hub bores are possible. These clutches canbe manufactured to conform to the acceptanceconditions of the classification institutions formarine engineering.Friction combination: Steel/sinter liningPressure and cooling oil intake: Via rotary inletthrough the shaft.Operating pressure: 25 barAreas of application: Used in marineengineering for reversing gears, variable pitchpropeller drives and multi-motor drives.

Sinus® multi-plate clutches for wet-run-ning; version for high thermal loading5 Series 0-002

A clutch for heavy duty drives of all types inwhich a high level of engaging/disengaging workhas to be performed; normally supplied with aflange or shoulder housing and without

“emergency engagement facility“. A version with“emergency engagement facility“ is also available.These clutches can be manufactured to conformto the acceptance conditions of the classificationinstitutions for marine engineering.Friction combination: Steel/sinter liningPressure and cooling oil intake: Via rotary inletthrough the shaftOperating pressure: 24 barAreas of application: Used in marineengineering for reversing gears, variable pitchpropeller drives, multi-motor drives and powertake off drives.

Spring-applied, hydraulically releasedmulti-plate brakes for wet- ordry-running, non centering6 Series 0022-. . 0/- . . 9

Spring-applied fail safe brakes with a housingwhich does not have a centering function; forthis reason these brakes are primarily used onshaft ends and outside gearboxes.Variations include a closed end flange and anopen end flange, which would allow a shaft topass through.The “wet-running plates“ are lubricated initiallyby soaking in oil or by means of oil stored in the
