Hydraulics
Hydraulic systems operate across pressure ranges from 50 bar to over 700 bar, with flow rates spanning 0.1 l/min to several thousand l/min depending on application - from precision servo-hydraulic control axes to heavy industrial presses. Key parameters including nominal pressure (PN), viscosity class (ISO VG 32-100), and contamination class (ISO 4406) determine system reliability over service intervals of 20,000+ operating hours. Core components such as cylinders, directional control valves, pressure relief valves, and filtration units must comply with ISO 4401, ISO 6162, and DIN EN ISO 4413 to ensure interoperability and safety across installations.
This catalogue covers 169,965 hydraulic products from leading manufacturers including Bosch Rexroth, Hydac, Enerpac, KTR, Stauff, and END Armaturen - spanning hydraulic cylinders, control valves, couplings, filtration, clamping tools, and pipe clamp systems. Components are sourced to meet international standards including ISO 4413, DIN EN 982, and ISO 6162-1/2 (SAE flange), supporting OEM procurement, MRO, and plant engineering applications worldwide.
