DADO s products are widely approved and used in global operations for many industries including metal stamping, automotive and plastic injection molding.

2 UH 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. UH eries Using the popular Ultra Force (U) eries technology, the UH eries is slightly taller and features a common G 1/8 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 UH mm (1.260 ) 810 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 fi lling/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 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.
