Series: WSL - Work Support | Product Line: Workholding Tools

• Low pressure lock-up capability enables the use of machine tool hydraulic systems
• High rated support capacities allow for more compact fixture design
• Corrosion resistant materials, compatible with most coolants and environments
• Threaded and manifold air vent ports allow fixturing that prevents coolants from being drawn into the system
• Minimized deflection increases machining accuracy
• Multiple mounting configurations allow design flexibility
• Can be operated as air advance by removing the spring and applying air pressure on the vent port
• Support force and clamping force must be matched. Support force should be at least 150% of clamping force.
• Do not exceed maximum flow rates to avoid premature lockup.
• Custom cylinders including longer stroke lengths are avaliable on request.
• Enerpac work supports provide either additional non-fixed location points to the clamps, or support to larger or thin section workpiece components, always in order to minimize workpiece deflection during machining.
