Swing cylinders Swing Cylinders Enerpac’s complete line of swing cylinders provide maximum clamping force in the smallest possible package. With several mounting and operation styles available, Enerpac can fit any clamping need you can think of. Our unique patented clamp arm design is an industry exclusive, and makes Enerpac’s swing cylinder line more versatile than ever before. Made to the highest quality standards, Enerpac swing cylinders will provide maximum performance and trouble free operation. Work Supports Enerpac’s line of work support cylinders gives you maximum holding force in a compact package. Incorporating innovative material combinations, our work supports feature the lowest lock-up pressures in the industry. Also, the use of corrosion resistant materials enables Enerpac work supports to stand up time and time again to even the most abrasive applications.

Selecting the swing cylinder for your applications Swing cylinders Work supports
Clamp arms transmit the force generated by swing cylinders
Determine the right size of your swing cylinder Clamp arm length and clamping force
Important L When using the standard and long clamp arms FT from the CAS and CAL series consult the diagrams shown on the next page.
02_001
The maximum operating pressure, clamping force and length of clamp arm will determine your size of swing clamp. The real operating pressure is a function of both the arm length and clamping force. In the chart below you select the required clamp arm length and clamping force. The use of different length clamp arms requires reduction in applied pressure and resulting clamp force. The diagrams on the next page show this relation.
The clamp arms transmit the force generated by the swing cylinder to the workpiece. Clamp arms are available in a variety of lengths. After you have determined the required clamp arm length and the clamping force you can select the swing cylinder type and mounting method.

then travel down an additional distance to clamp
• The obvious choice when there are few system restrictions, and there are not many units retracting simultaneously
against the fixtured part. Upon release of clamping pressure, the clamp arm rotates back 90 degrees
• Fewer valving requirements which results in a less complex circuit
in the opposite direction to allow for part removal and new part placement.
• Innovative clamp arm design allows quick and secure arm positioning
Double-acting • Used when greater control is required during the unclamp cycle • When timing sequences are critical: less sensitive to system back pressures, resulting from long tube lengths or numerous components being retracted at the same time • Innovative clamp arm design allows quick and secure arm positioning ❚ Swing cylinders used in conjunction with work supports and other Enerpac components to positively hold the workpieces during machining operations.
Collet-Lok® Positive locking • Enerpac Collet-Lok® positive locking cylinders are designed to mechanically hold the workpiece while hydraulic pressure is removed. After machining, hydraulic pressure is applied to unclamp the workpiece • Used when live hydraulics are not available during the clamp cycle or when parts must be held for long periods of time

The upper flange swing cylinder has a bolt pattern which is identical to its lower flange equivalent, enabling interchangeability.
In case there is a risk of machining coolants and debris being inhaled via the breather vent, it is recommended to pipe this port to an area outside the fixture that is protected from machining coolants and debris.
Do not exceed maximum flow rates.

Swing cylinders - Collet-Lok® design Shown: MPFR-100, MPTR-100 Swing cylinders Work supports
Ideal when live hydraulics are not available …clamping is maintained mechanically so live hydraulics are not required during the machining cycle • Double acting Collet-Lok® action allows fully automated operation • Additional level of safety since live hydraulics are not required • Collet-Lok® swing cylinders can either be mounted by the flange, or threaded into the fixture

• Vise not required for fastening arms
Pressure vs clamping force
Clamp arms are used to transmit the force generated by the swing cylinder to the workpiece. Enerpac’s
The use of different length clamp arms requires reduction in applied pressure and resulting clamp force. The diagrams on page 10 below show this relationship.
patented clamp arm design attaches to the hydraulic swing cylinder, allowing parts to be clamped at various distances from the hydraulic cylinder. Clamp arms are available in a variety of lengths, or you can use custom machining dimensions to create your own clamp arm configuration.

When designing custom clamp arms, the flow rates must be further reduced. This rating should be in proportion to the mass and the centre of gravity of the clamp arm.
Q

Example: If the mass of the arm is twice that of the long arm, flow rates must be reduced by 50%.

Wide range of sizes and types to efficiently support workpiece • 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 • Collet-Lok® positive locking models: Hydraulic actuation / mechanical holding allows for palletized systems which do not permit live hydraulics
The Enerpac work support is a hydraulic means of positively supporting the workpiece to minimize deflections. The work support automatically adjusts to the contour of the workpiece, and then locks in

variations.
• Retracted plunger allows unobstructed workpiece loading. • Internal hydraulic plunger advances allowing external plunger to advance under spring load. Bronze sleeve squeezes and holds plunger in fixed position. 30 WS series, Spring advance • Workpiece weight compresses the spring of the extended plunger. • When pressurized, the internal bronze sleeve squeezes and holds the plunger in fixed position.
❚ Lower flange work supports, placed close to the machining area to minimize deflection of the workpiece.
• Can be operated as air advance. 32 MP series, Collet-Lok® positive locking • Unique in the industry. Allows the work support to maintain support after pressure has been removed. • Extremely low deflections due to the structural design of the collet system.
