2 UH eries Nitrogen Gas prings Introduction Installation Examples UH eries Nitrogen Gas prings The global leader in nitrogen gas spring technology DADO produces top quality products at competitive prices and provides a superior level of customer service. Founded in 1958, DADO is the highest volume producer of gas springs for press tools. DADO s products are widely approved and used in global operations for many industries including metal stamping, automotive and plastic injection molding. UH eries Using the popular Ultra Force (U) eries technology, the UH eries is slightly taller and features a common port for linked operations. The UH eries has eight models and provides force up to 7.4 tons on contact. Many stroke lengths and mount options are available for new or existing applications. High Quality onstruction To ensure their exceptionally long service life, DADO s UH eries Gas prings have high quality construction features. All models are built with a one-piece piston rod and utilize a double lip rod seal for excellent load capacity and resistance to wear. 2 Model Diameter Maximum Force on ontact UH00 32 mm (0 ) 810 lb.

(2386 dan) UH mm (3.740 ) 9532 lb. (4241 dan) UH mm (4.724 ) lb. (6627 dan) Adjustable Force For convenience, self-contained cylinders usually are delivered pre-charged to the desired force and ready to install. If force adjustment is ever needed, a filling/draining port is located in the cylinder for safe, easy access. UltraPak Technology The UH eries uses the same superior UltraPak cartridge as the popular U eries. The UltraPak employs advanced materials to reduce the rod cartridge profile while increasing performance. The UltraPak is comprised of a rod wiper, rod seal and guide arranged to extend life, retain lubrication, exclude contaminants, and provide excellent wear characteristics. When coupled with DADO s superior finished piston rod, the UltraPak is the ultimate sealing system in compact height gas springs. Numerous Piping Options Many customers have recognized the benefits of piping gas springs to monitor, control, and adjust force from outside the die. DADO offers a wide selection of hoses, fittings, control panels and equipment to simplify the piping process.

13 Technical Data AUTION DO NOT attempt maintenance on spring until internal pressure is exhausted. Operating pecifications harging Medium: Nitrogen Gas UH00 harging Pressure: 180 bar (2 psi 2600 psi) UH.0600 UH.6600 harging Pressure: 0 bar (2 psi 2175 psi) Operating Temperature: ( F 160 F) Maximum peed:.5 m/sec ( in/sec) % * 0.9 F.1 F.3 Installation Requirements Provide troke Reserve DADO UH eries gas springs will permit travel of the full nominal stroke; however, at least a 10% stroke reserve is recommended to achieve optimal performance and safety (F.1 and F.2). Avoid ide oading A misaligned press or die can cause side loading that increases wear on the bearing, seal, and piston rod (F.4). Therefore, avoid side loading when possible (F.3). Rod End Thread The end of the piston rod has a construction thread intended for assembly and disassembly purposes only, and should never be used to mount or secure the gas spring (F.4). Die vibration and/or misalignment will damage the spring. > * 0.9 F.2 >1 F.4 Protect From Fluids Drain Hole Direct contact with certain die lubricants and cleaners should be avoided (F.6). Protect gas springs by providing adequate drainage in gas spring pockets (F.5). F.5 Discharging elf-ontained Gas pring F.6 The DADO Pressure Analyzer (.3.5) detailed on page 21, allows for charging, discharging and gauging of the pressure in the UH eries gas springs (F.7). For information on completely exhausting the gas spring refer to DADO s UH eries Maintenance Instructions. Recharging elf-ontained Gas pring 100% F.7 F.9 Hold the spring vertically at all times during filling. Never compress the gas spring in a vice or clamp outside of the die or application as damage to the gas spring can result (F.8). Never fill a gas spring unless the rod is in the fully extended position (F.10). Thread the T-handle (.3.1 or.3.2) detailed on page 21, into the rod end and depress the valve stem with the Valve Bleed Tool (.360.4) or Port ervicing Tool (.3.8), detailed on page 22. Pull the rod cartridge assembly up until it is seated firmly against the retaining ring (F.9). Remove the T-handle from the rod and charge the gas spring to the desired pressure. Refer to DADO s UH eries Maintenance Instructions for complete step-by-step instruction.
