Anoperating pressure p of 200 bar in connectionwith standard clamping arm 0354-003 of max.arm length L = 75 mm results in an effectiveclamping force F Sp of 5.8 kN.Example 2: 1885-102 single acting. For adesired effective clamping force F Sp of 8 kNand use of a swing clamp 1885-102 with astandard clamping strap 0354-002 anoperating pressure p of 345 bar is required.Important notes1. Danger of injuryHydraulic clamping elements can generateconsiderable forces.Due to the 90° swing motion, the exactclamping and unclamping position cannot bedetermined in advance. Considerable injuriescan be caused to fingers in the effective areaof the clamping arm.Remedy: protection device with electricallocking.2. Maximum oil flow rateIn case of the maximum oil flow rate as perchart the shortest possible clamping time is1 second. If the flow rate of the pump dividedby the number of swing clamps is higher thanthe indicated value in the chart, the flow ratehas to be throttled to avoid snapping out ofthe overload protection device. In the casethat the mounting position is not verticaland/or heavy clamping arms are used, theflow rate has to be further reduced, if required.Throttling has to be made in the oil supply lineto the swing clamp to rule out a possible pressureintensification. Use only flow controlcheck valves which allow oil return from theswing clamps without any impediments, ase.g. the flow-control swivel banjo coupling9208-129 on page C 2.9501.During unclamping the maximum oil flow ratecan be 2.8 higher than the indicated value inthe chart, because the piston area is correspondinglybigger.3. Unimpeded swing motionThe swing motion must not be impeded andthe clamping arm may only contact the workpieceafter completion of the swing stroke.4. Clamping arm assemblyIn case of this threaded-body type the clampingarm can only be fixed, after firm screwingin of the housing, since the final positioncannot be determined in advance.When tightening and untightening the fixingscrew , the clamping arm has to be backedup to avoid the introduction of moments to thepiston rod.5. Adjustment of contact boltThe contact bolt may only contact the workpieceafter completion of the swing motion.When tightening and untightening the fixingscrew, the clamping arm has to be backed up(see 4.).6. Special clamping armsWhen using special clamping arms with otherlengths, the corresponding operating pressuresas shown in the clamping force diagrammust not be exceeded. If longer clampingarms will be used, not only the operating pressurebut also the flow rate have to be reduced(see 2.).7. Venting of spring areaThe spring area of single-acting swing clampshas to be vented to avoid problems in functioning.A sintered metal air filter avoids penetrationof contaminations. If there is a possibilitythat cutting lubricants and coolants penetratethrough the sintered metal air filter into thecylinder’s interior, a vent hose has to beconnected and be placed in a protectedposition (see data sheet A 0.110).8. BleedingAir in the oil prolongs the clamping time considerablyand leads to function problems. Thereforebleeding has to be effected during startup. The threaded-body swing clamp has nopossibility for bleeding at the element itself.Remedy: plug the oil channels in the fixturebody at the end. If required, loosen the plugscarefully and pump at low oil pressure untilbubblefree oil comes out. Retighten the plugs.Römheld GmbH Actual issue see www.roemheld.com 3B <strong>1.892</strong> / 12-10 ESubject to change without prior notice
