1 Pneumatic cylinders mm according to ISO 643 and VDMA 56 with adjustable cushioning UNIVER pneumatic cylinders which comply with ISO 643 and VDMA 56 standards, take advantage of the improvements arising from the research of the last years; infact, they can fully satisfy the most demanding users. The operation with non-lubricated air is worth mentioning, since it allows their use in many industrial sectors while protecting the environment. The strong construction and the selected components contribute to giving them excellent operating features and a very long life. TECHNICAL CHARACTERISTICS Working pressure:,5 bar Ambient temperature: - 8 C. Fluid: filtered air, with or without lubrication. Barrel: internal/external anodised aluminium and piston rod in chromium-plated steel standard. Bores: series KD 5 aluminium barrel with profiles for flush-mounted sensors, magnetic version standard. series K aluminium barrel; mm with round aluminium barrel and steel tie-rods, magnetic version upon request. Series KD VDMA 56 Series K---- Codification key Flush-mounted magnetic sensors DF---- series for KD series. Wire protection strap magnetic sensor for KD series part no. DHF-. Magnetic sensor DH---- Series for K series. (Section Accessories page ) Accessories as from page 5. Upon request - Magnetic rings in plastoferrite - Locking units 5 mm to be coupled only with chromium-plated steel rod series KD- (section High-Tech page 3) - Slide units mm (section High-Tech page ) - with rigid bushing, in tandem, multiple position and opposed version (page 3). Construction details Clean line barrel produced from extruded aluminium alloy with ribbed "anti-twist" design. Internal and external surfaces anodised to 5 micron. Die-cast end-caps in aluminium alloy mounted on the barrel holes with self-tapping steel screws. Pneumatic adjustable cushions provide efficient piston deceleration. Synthetic rubber shock absorbers avoid mechanical stress and reduce machinery noise (lower than 5 db). Die-cast aluminum alloy piston and guide shoe in acetalic resin with a permanent plastoferrite magnetic ring (upon request for the magnetic version). The piston and cushion seals are made of a wear-resistant nitrile rubber compound suitable for applications with or without lubrication. The double lip seal design automatically selfcompensates against wear. Hardened stainless steel rod (K-KD... series) or chromiumplated (K-KD... series) with micron Ra.; supplied with nut. UNIVER original self-lubricating and self-aligning piston rod bush. For special applications, rigid bushings are supplied upon request. 5-- with rigid piston rod bushing standard supplied.
