Rigid coupling 85 series

for machine toolscompact

Compact cartridge couplings for cavities in customers’ machines, designed specifically for machine tool requirements. The coupling elements are equipped with clean-break technology that release a minimum amount of media when disconnected. Operation is versatile thanks to integrated misalignment tolerance during connection and small connection force. Pressure range: Max. clamping pressure 240 bar (3480 psi) Media: Suitable for all common hydraulic oils Materials: high-quality case-hardened steel, oil-burnished, combined with robust seals made of FKM / P Special features: Ultra short couple stroke Prevents dirt ingression due to encapsulated seals Easy to connect even against residual pressures up to 40 bar, 580 psi (coupling to adaptor); 60 bar, 870 psi (adaptor to coupling) Your advantage: quick moving of pallets even in demanding operating cycles Example: hydraulic clamping for pallet changing systems The WALTHER programme offers more coupling elements for special requirements
