采用了高质量的制造 材料以及良好的密封 因此在工业中得到广泛应 用 HC2 SERIES 20 71 000 103 ED 2 28 1 1 1 25 200 standard piston rod with 1 1 25 area ratio oversized piston rod with 1 2 area ratio 1 2 Cushioning devices are always recommended as they ensure impact free stopping even at high speed thus reducing pressure surges and impact transferred to the mounting supports For all the avaible bores cushioning is adjustable by means of a needle Rapid piston start up is guaranteed by the bypass valves located inside the front cushioning cone and rear cushioning ring The table below shows cushioning cone lengths 1 3 The cylinders are supplied as standard with cylindrical BSP threads and spot facing for seal rings in compliance with ISO 1179 For correct cylinder operation fluid velocity must not exceed 5 m s 1 4 1 5 1 6 Standard cylinders are available with strokes up to 1500 mm Longer cylinder strokes can be supplied on request Stroke tolerances are 0 1 mm for strokes up to 1000 mm 0 4 mm for strokes above 1500 mm 1 7 Spacers In the case of cylinder strokes above 1000 mm we recommend the use of spacers which can be inserted to reduce loads on the piston rod bushing and prevent the piston from sticking Spacers are constructed in hardened and tempered steel with PTFE facing Recommended thicknesses are 50 mm for strokes from 1001 to 1500 mm 50 mm increments for every 500 mm stroke For double rod cylinders the spacer length is divided between both sides The thickness of the spacer increases the overall length of the cylinder accordingly Indicate the working stroke of the cylinder in the identification code and the number of spacers in increments of 50 mm 1 8 Tie rod tightening torque In the event of cylinder disassembly re assemble and tighten the tie rod lock nuts cross wise applying a gradual torque up to the value indicated in the table below The values below refer to dry threads 1 9 Breathers On request cylinder ends can be supplied with breathers for the elimination of air This is necessary when the entire stroke is not used or when connections are not facing upwards 1 10 Surface finish The cylinders are supplied painted with Duplomatic black opaque colour with a paint thickness of 40

compressive load according to the following simplified procedure Refer to the table to identify the stroke factor according to the mounting style To calculate the reference length multiply the working stroke by the stroke factor To calculate the thrust force multiply the total cylinder area by the operating pressure On the diagram find the point of intersection between the thrust force and reference length Identify the minimum rod diameter on the curve above the previous point of intersection Cyli
