Hydraulic Clamping Fundamentals

Fluorocarbon seals are available as an option, but have a significantly shorter life than standard seals. When the fixture is taken out of service, it is important that the swing clamps be cleaned of coolant residue before storage. Failure to clean this residue may result in the swing clamps sticking when returned to service. The swing clamps are designed to function with an ISO 32 grade hydraulic fluid. Contact your fluid manufacture for seal compatibility recommendations if use of a synthetic or water based hydraulic fluid is intended. APPLICATION RECOMMENDATIONS Swing Clamps can be mounted in any position relative to the work-piece. However, size, orientation, and swing direction of the arm should always be considered, especially in single acting applications. For optimal life and performance, avoid contact with arm during positioning movement. The load applied should be applied parallel to clamp centerline. Avoid using rotational section of travel to push or pull on an external load.

Application Information

Max. Hyd. Op. Pres. - 5,000 psi Min. Hyd. Op. Pres. - single acting - 750 psi Min. Hyd. Op. Pres. double acting - 500 psi Max. Op. Temp. - 160 F Min. Op. Temp. - 40 F Max. Flow Rate – Determined by positioning speed of clamp arm. (See positioning time restraints in general information section) Hyd. Fluid Filtration - 25-micron o o


For best performance, hydraulic circuits should be designed so that the swing clamps have adequate flow to cycle clamps in required time frame without exceeding maximum speed requirements. On single acting swing clamps, use caution in circuits with multiple devices so that the backpressure does not affect clamp return. continued...
