Equipment and spare partsBrowse manufacturers Search by manufacturerFounded in 1898 in Germany, Ortlinghaus-Werke GmbH is a world-renowned pioneer in combined clutch-brake units (CBU), hydraulic multi-plate wet clutches, failsafe spring-applied brakes, and sintered friction discs. We supply genuine Ortlinghaus drive assemblies for stamping presses, marine propulsion, mining mills, and heavy metallurgy.
Ortlinghaus combined clutch-brake units Series 0406, 0420 (including Size 87, Series 0420-149 with 12-point drive disc), 0086, 0088, 0480 (Cee.go), and 0488 are engineered for mechanical crank presses, hot forging lines, blanking presses, and shearing machines. The single-piston architecture physically prevents overlap between clutch engagement and brake application, minimizing rotational inertia and thermal build-up under high single-stroke cycles. Modular design enables rapid replacement of friction segments directly on the press shaft without dismounting the flywheel. Pneumatic variants operate at 5.5–6.0 bar air pressure, while hydraulic heavy-duty units manage pressures up to 80 bar and torque absorption up to 1,400,000 Nm on industrial forging and stamping presses.
Ortlinghaus multi-plate hydraulic clutches Series 0021, 0023, 0026, 0202, and 0002 operate in oil-cooled wet environments with forced circulation. Sintered bronze plates supplied with lubricating oil (including flame-retardant lubricants like Castrol Anvol SWX 46) achieve near wear-free operation and high torque transmission across marine gearboxes, thrusters, generator drives, mining mills, and rolling equipment. The optimized outer diameter to shaft bore ratio enables shorter axle center distances in gearboxes, lowering overall drive dimensions and machine weight. Symmetrical access to internal plate stacks simplifies routine maintenance procedures in compact marine and industrial installations.
Ortlinghaus electromagnetic clutches and brakes Series 0008, 0009, 0013, 0100, 0120, 0122, and 0130 deliver rapid-response motion control across machine tools, packaging lines, textile machinery, and printing presses. Dry single-face clutches in Series 0008 guarantee millisecond response upon energization and zero residual drag torque when disengaged. Series 0013 electromagnetic tooth clutches transmit torque through hardened precision-machined face teeth, eliminating mechanical slippage under high torque loads. Slip-ring-free brushless magnetic coils eliminate electrical contact sparking and brush wear, assuring maintenance-free service.
Ortlinghaus spring-applied safety brakes Series 0022, 0128, 0171, and 0172 (Prot.act) provide failsafe clamping and emergency stopping for heavy industrial drives. Braking torque is generated by disc spring packs whenever hydraulic fluid pressure is discharged, ensuring instantaneous mechanical arrest of press rams and winches upon power failure. The patented Prot.act generation (Series 171/172) is specifically engineered for servomotor-driven presses. Certified conforming to DIN EN ISO 16092, Prot.act features an exceptionally low moment of inertia and a fully enclosed dust-tight housing preventing cleanroom contamination.
Ortlinghaus uniquely combines clutch engineering with in-house development and manufacture of friction materials. The portfolio spans sintered bronze plates with micro-porous matrices for continuous oil lubrication, precision-ground alloy steel counterplates, and organic/composite friction discs for dry applications. Internal and external splines are broached adhering to DIN 867 and DIN 5480 standards or custom specifications. Optimized spiral and radial cooling grooves prevent hydrodynamic disc stiction in the disengaged state while facilitating heat removal under cyclic braking.
Ortlinghaus rotary inlets and rotary unions Series 0017, 0019, 0029, and 0086/0087 deliver pressurized hydraulic oil, compressed air, and cooling fluids into rotating machine shafts feeding clutches and brakes. Precision mechanical face seals with ceramic and silicon carbide pairings ensure fluid tightness at rotational speeds reaching 6,000 RPM. The product range includes single-passage pneumatic unions for press clutch-brakes as well as multi-passage rotary joints with segregated circuits for high-pressure actuation oil and low-pressure cooling oil. Direct shaft-end mounting is facilitated via flange or threaded adaptors.
Ortlinghaus compact drives Series 0045 and 0046 combine a flywheel, high-torque planetary gearbox, wet-running clutch-brake unit, and integrated lubrication circuits into a single monobloc housing. This compact configuration cuts axial press drive space by up to 50%, reduces dynamic foundation shock loads, and enhances overall machine energy efficiency. Planetary gear trains are carburized and ground to withstand harsh cyclic shock forces generated during metal forming. Integrated pressure, temperature, and oil flow telemetry sensors track drive status, safeguarding 24/7 industrial production lines against unexpected downtime.
To actuate and cool clutches and brakes, Ortlinghaus delivers engineered hydraulic power units, PSV safety valves (PSV 18/31 rated up to 100 bar), proportional electro-hydraulic manifolds (Series 0086–0392), and the DC650 digital diagnostic platform. The system monitors pressure dynamics, flow rates, temperatures, and plate lining wear in real time. PSV safety valves feature redundant flow paths ensuring instantaneous depressurization when press emergency stop circuits are tripped. The DC650 telemetry platform logs switching cycles and calculates remaining friction lining thickness to facilitate predictive upkeep.
Our drivetrain engineers perform comprehensive sizing calculations covering static and dynamic torque ratings, emergency stopping times under DIN EN ISO 16092, cyclic thermal energy dissipation on friction plate surfaces, and cooling oil flow rates. We configure matching clutch-brake units (Series 0406, 0420, 0123) and hydraulic control power packs.
We supply and support Ortlinghaus clutches and brakes for premier international press builders (Schuler, Aida, Komatsu, Fagor Arrasate, Mueller Weingarten) as well as marine propulsion systems, thrusters, and heavy deck winches (Rolls-Royce Marine, Wartsila, Schottel, Berg Propulsion).
All Ortlinghaus assemblies are manufactured in Germany and Switzerland adhering to ISO 9001 quality systems and DIN EN ISO 16092 safety regulations. Every unit undergoes 100% factory dynamic testing for hydraulic sealing integrity, switching timing precision, and torque transmission capacity on dedicated test rigs.
All genuine Ortlinghaus products are supplied directly from European manufacturing facilities in heavy-duty export packaging, accompanied by factory inspection certificates, hydraulic pressure test protocols, and detailed engineering dimensional blueprints, supported by reliable global multimodal logistics.
