They are maintenance free, self-contained and PRICED RIGHT with qUICk DELIvERY.Enertrols gas springs remove the need for muscle power and provide controlled motion for lids, hoods, machine guards, panels and more.Body diameter models are available from 15 mm to 28 mm with forces ranging from 10 N to 2,500 N.Enertrols gas springs offer a high service life with a treated steel piston rod and precision steel body. In addition, these durable models offer an integrated low friction bearing with a grease chamber that provides a very low break away force. These unique features make the Enertrols gas springs superior to conventional gas springs.They can be mounted in any orientation, although mounting with the rod in the downward position is preferred. The internal valve allows the force to be adjusted to your specific requirements.A wide variety of end fittings make installation easy and versatile.Aerospace • Defense • Transportation • RV Medical • Furniture • Packaging • Printing Amusement and MoreEGS-15 - EGS-28 Gas SpringsGas SpringsSelf-Contained, Maintenance Free Treated Steel RodPrecision Steel Body Variety of End FittingsPriced RightQuick Delivery(734) 595-4500 • fax (734) 595-6410 • email: customerservice@enertrols.com • www.enertrols.comGas Spring ApplicationsComputersPhotocopiersAircraft Overhead CompartmentsAircraft Galley EquipmentTruck Engine CoversTruck Side PanelsElectrical Enclosure CabinetsBoat Engine HatchesBus/Coach Engine CoversBus/Coach Courier SeatsFork LiftsConveyor Belt TensioningRoof Ventilation HatchesManhole/Access Covers Molding MachinesExecutive DesksSmoke VentsStair LiftsSecurity CabinetsWashing Machine LidsAutomatic Cash DispensersAdditional Gas Spring Applications Include:(734) 595-4500 • fax (734) 595-6410 • email: customerservice@enertrols.com • www.enertrols.comVarious mounting options available (adjustment valve included, except fixed models)Oil zone filling for end position damping and lubrication Integral grease chamber for increased lifeFilled with high pressure nitrogen gasMetering orifice for defined extension velocitiesTreated steel rodPrecision steel bodyGas Spring Function, Construction and OperationIn every action involving a lifting or lowering motion, e.g. when opening a hatch lid, there are moving masses which must be controlled.If this is ignored, then the kinetic energy caused by the moving mass can result in considerable damage. There are several ways that Enertrols offers to control this motion.Gas springs can be provided in a wide range of body sizes and stroke lengths. The force provided can be specified to suit the specific application. The extension velocity can also be customized on request.Enertrols gas springs are maintenance free self-contained systems which are filled with high pressure nitrogen gas to a defined force. They also contain a small quantity of oil to provide end position damping.During operation, the nitrogen gas flows through the metering orifice and allows the load to be lowered in a controlled manner. The force of the gas spring works against the weight and prevents it from accelerating and damaging mechanical components on closure.Upon reversal, the nitrogen flows back through the piston orifice and the gas spring force assists the action, reducing the effort required to reset the mechanism.The extension speed can be varied by altering the size of the metering orifice. For cushioning at the end of the extension stroke, mount with the rod down. For cushioning at the end of the compression stroke, mount with the rod up.An integral grease chamber behind the rod seals ensures lasting lubrication which can increase the life of Enertrols gas springs by at least 100% compared to other products on the market.The treated steel rod and painted precision steel body offer excellent corrosion protection and provide a long maintenance free working life.The wide variety of available mounting accessories provide mounting versatility and options.Safety note: if very high demands are placed on durability and stability, please avoid the combination of small diameter + long stroke + high force.FunctionConstruction and Operationa) Shock absorbers - used when no return assistance is required and no restriction of the velocity is required. Control is provided shortly before the mechanical components make contact.b) Velocity controls - used when no return assistance is required, and control of velocity throughout the motion is required.c) Gas springs - used when return assistance or load support (counterbalance) is required throughout the motion.On the extension stroke of the gas spring, for example when opening a car tailgate, the nitrogen gas flows through the metering orifice in the piston to provide a controlled opening speed and the oil zone provides damping at the fully open position to avoid impact damage.The gas spring should be mounted rod down for this damping to be effective. On closing the tailgate the gas spring helps support the weight.(734) 595-4500 • fax (734) 595-6410 • email: customerservice@enertrols.com • www.enertrols.comWF1FHGas Spring Calculations and Mounting InstructionsCalculationsIn order to save time we recommend that the calculation and selection of the most suitable gas spring be completed by Enertrols.With our sophisticated selection software we can quickly determine the resultant opening or closing forces throughout the complete movement and recommend the optimum mounting points, gas spring model and nominal force.Please fax the completed Application Data form on page 10 to 734-595-6410.Gas spring force F1: Gas springs are filled with nitrogen at very high pressures and under no circumstances should they be opened or subjected to excessive tensile loads.External force FH: forexample manual (hand)force to close the flap.Weight force W: due to mass acting at center of gravity.Gas spring orientation as desired:With piston rod downward – damping effective at end of extension stroke.With piston rod upward – damping effective at end of compression stroke.Symbols used:W Force due to weight of the lid lbs (kg) RW Radius of center of gravity in (mm) LG Distance to gas spring in (mm) s Center of gravity - D Pivot point n Number of gas springs in parallelUse the following application parameters to calculate a suitable Enertrols gas spring:1.

The gas spring body must not be deformed or damaged.The gas spring must not be exposed to bending forces or side loads. If using eyelet fittings support the eye on both sides and allow some float. We recommend using ball joints on most applications as these help to eliminate misalignment.RWF1sWDLGEnertrols gas springs are self contained, maintenance free devices and are supplied ready for installation.The following points should be noted to ensure the longest possible working life:Mounting InstructionsF1W • RWlbs (N)LG • n(734) 595-4500 • fax (734) 595-6410 • email: customerservice@enertrols.com • www.enertrols.comGas Spring CharacteristicsAdditional Gas Spring Available OptionsGas Spring Force - Stroke CharacteristicsGas Springs – Push Type1.

They are available with body diameters from 0.59 in (15 mm) to 1.57 in (40 mm) and with stroke lengths of up to 31.51 in (800 mm).Unlike standard Hydraulic Dampers that include free travel up to 20% of stroke, these dependable units have no free travel and are ideal for applications that require this level of performance.Double-acting Hydraulic Dampers are standard. However, a single acting design is available. Adjustment is easily achieved by pulling and turning the rod until the desired damping speed is achieved.The travel speed is adjustable and remains constant throughout the stroke. The single acting version is controllable in one direction only, with free-flow in the opposite direction. A built-in antilock guard allows adjustment to be made at any damping rate without unit lock up.These reliable units offer a minimum of 250,000 cycles and are available for QUICK DELIVERY. A variety of end fittings are available for ease of operation and installation. A, C & D end fittings are included with the damper.Typical applications include: process control, machine guards, lids, hatches, fire safety doors, arms for medical equipment, conveyors, swinging loads, machine tools, lift gates, drill feed control, amusement park rides, and more.Medical • Furniture • Wind & Solar Energy •Fitness • Transportation • RV • Amusement • and MoreSingle & Double ActingA, C & D End Fittings Included250,000+ Cycle LifeMaintenance FreeEasily AdjustedAn outstanding value line of Hydraulic Dampers with QUICK DELIVERY...wide range of body sizes, stroke lengths and damping forces(734) 595-4500 • fax (734) 595-6410 • email: customerservice@enertrols.com • www.enertrols.comEyelet0.24(6)0.59(15)0.63(16)StrokeL ± (2 mm) extended+ max (6 mm) at maximum adjustment0.080.24A0.85(21.5)Clevis forkAngle ball jointStud threadCB0.20(5)0.87(22)1.12(28.5)D0.79(20)M5 x 0.80.51(13)0.35(9)18° 18°0.31(8)M50.35(9)B0.20(5)0.20(5)0.39(10)0.39(10)0.20(5)CD0.27(7)0.12 thick(3 thick) R0.20(R5)0.24(6)0.33(8.5)0.43(11)A1.02(26)Swivel Eye EE1.18(30)0.23(6)0.39(10)0.51(13)0.23(6)1.57(40)max. permitted force (500 N)112 lbsModel Stroke L extendedMax Compression Force (N)EHBD 15-25 .98 (25) 5.71 (145) 800EHBD 15-50 1.97 (50) 8.66 (220) 800EHBD 15-75 2.95 (75) 11.61 (295) 800EHBD 15-100 3.94 (109) 14.57 (370) 350EHBD 15-150 5.91 (150) 20.47 (520) 350Self-contained and maintenance free.Mounting position: can be mounted in any positionAdjustment: pull the piston rod out to its fully extended position.
