The plunger rod andthe attached clamp arm rotate 90 degrees in either aclockwise or counter-clockwise direction, then traveldown an additional distance to clamp against thefixtured part. Upon release of clamping pressure,the clamp arm rotates back 90 degrees in theopposite direction to allow for part removaland new part placement.Roller in groove• Double index provides low heightdesign to minimize fixture height• Overload clutch allows clamp todisengage if needed to preventdamage due to improperpart loadingBall in groove• Rotation direction can be changedon-site to reduce spare inventoryby 2/3 (67%)• Ball and cam rotation ensuressmooth accurate operationSelect your swing cylinder type:Single acting• The obvious choice when thereare few system restrictions, andthere are not many units retractingsimultaneously• Fewer valving requirements whichresults in a less complex circuit• Innovative clamp arm design allowsquick and secure arm positioningDouble acting• Used when greater control is requiredduring the unclamp cycle• When timing sequences are critical:less sensitive to system backpressures, resulting from long tubelengths or numerous componentsbeing retracted at the same time• Innovative clamp arm design allowsquick and secure arm positioning❚ Swing cylinders used in conjunction with work supportsand other Enerpac components to positively hold theworkpieces during machining operations.Collet-Lok ® positive locking• Enerpac Collet-Lok ® positivelocking cylinders are designed tomechanically hold the workpiecewhile hydraulic pressure is removed.After machining, hydraulic pressureis applied to unclamp the workpiece• Used when live hydraulics are notavailable during the clamp cycle orwhen parts must be held for longperiods of time• This design is an industry exclusive98-001For Collet-Lok ® positive lockingswing cylinders, see 24 10© 2008www.enerpac.com
