2 UT eries Nitrogen Gas prings Introduction 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. UT eries This series consists of fi ve models and provides force up to 95 on contact. Each model comes standard with a G 1/8 charging port for consistent link capability using the Zip (NOMO) Fittings and hose. Optionally, the UT.1000 and UT.2600 models are available with a pressure indicator installed for quick monitoring at a glance during operation. Model Diameter Maximum Force on ontact UT mm 9.24 UT mm UT mm UT mm UT mm High Quality onstruction To ensure their exceptionally long service life, DADO s UT eries Gas prings have high quality construction features. UT gas spring models are built with a one-piece piston rod and utilize a double lip rod seal for excellent load capacity and resistance to wear. UltraPak Technology The UT eries incorporates superior gas spring technology into DADO s UltraPak cartridge. The UltraPak employs advanced materials to reduce the rod cartridge profi le 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 fi nished piston rod, the UltraPak is the ultimate sealing system in compact height gas springs. Numerous Piping Options Many customers have recognized the benefi ts of piping gas springs to monitor, control, and adjust force from outside the die. DADO offers a wide selection of hoses, fi ttings, control panels and equipment to simplify the piping process.

3 Installation Examples UT eries Nitrogen Gas prings DADO offers a variety of mount options to meet specifi c customer applications. Installation and fastening of the gas springs should take into consideration load support, fastener selection and torque values. For additional information on installation requirements see page 16. ylinder and mount dimensions are shown on pages ød ød > /2 > 25.4 Drain Hole < ød/2 ød RM/RN Basic Model in a fl at bottom pocket. The pocket must be bored with a fl at bottom, or a spacer must be used to create a fl at surface. RM/RN Basic Model mounted inverted requires back-up to support the full load. Retain inverted cylinders tight in the pocket with the appropriate length cap screw to eliminate movement. RM/RN Basic Model mounted to a plate. inked cylinders require clearance for the hose and fi ttings. T -.1 B43-B48 mounts must installed onto a flat surface. When mounted inverted, back-up is required to support the full load. ød B21/B25 mounts must be fastened to the top groove only. The wire ring supplied with mounts supports the full load. > D+1 >.5 > ¾ ød H > H+ d/2 ød B40 mounts require back-up to support the load. RM/RN Basic Model mounted in a horizontal pocket. Allow clearance in the rod pocket to avoid contacting the body of the cylinder during operation. Allow the rod to locate freely.

Indicator DADO offers an optional pressure indicator for the UT.1000 and UT.2600 models. This indicator is preset and installed in a special G 1/8 port and designates that the gas spring pressure is above the preset value. The charging pressure must be a minimum of 20 bar/2 MPa above the preset value when the indicator is installed; refer to ordering example. The pressure indicator requires manual reset upon recharging. ontact DADO for more information.

16 UT eries Nitrogen Gas prings Technical Data AUTION DO NOT attempt maintenance on spring until internal pressure is exhausted. harging Medium: harging : Operating pecifications Nitrogen Gas bar ( MPa) Operating Temperature: Maximum peed: 1 m/sec Provide troke Reserve DADO UT 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). 90% * 0.9 > * 0.9 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. F.1 F.3 >1 F.2 F.4 Protect From Fluids 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). Drain Hole Discharging elf-ontained Gas pring The DADO Analyzer ( ) allows for charging, discharging and gauging of the pressure in the gas springs (F.7). F.5 F.6 Recharging elf-ontained Gas pring Hold the spring vertically at all times during fi lling. 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 fi ll a gas spring unless the rod is in the fully extended position (F.10). Thread the T-handle ( ), into the rod end and depress the valve stem with the Valve Bleed Tool ( ) or Port ervicing Tool ( ). Pull the rod cartridge assembly up until it is seated fi rmly against the retaining ring (F.9). Remove the T-handle from the rod and charge the gas spring to the desired pressure. Refer to the Maintenance Instructions for complete step-by-step instruction. onverting from elf-ontained mode to inked mode Remove Port Plug (A.1). Exhausting the pring With the cylinder in the horizontal position, exhaust the gas spring by depressing the valve stem using the appropriate tool (A.2). Keep face and hands clear of the port. After all the gas pressure is exhausted, be sure that the piston rod will retract into the tube manually. If not, try depressing the valve stem again. If still unsuccessful TOP and contact your DADO ervice Representative. Remove Valve Remove the valve by unscrewing it using the appropriate tool (A.3). Ready to Pipe Install a port adapter into the open G 1/8 port, (A.4).
