  Telescopic hydraulic cylinder   provide an extended reach while maintaining a compact retracted form. Sometimes called telescoping cylinders or multi-stage cylinders, telescopic cylinders are ideal for heavy-duty equipment with space restrictions. A telescopic hydraulic cylinder has a number of sections of  honed steel tubes  with successively smaller diameters that nest inside each other. This results in a small compact hydraulic cylinder when in its retracted state that offers a long length of travel when extended. Telescopic cylinders usually extend from the largest stage to the smallest, this means that the largest stage with all the other sections nested inside will generally move first and complete its stroke before the next section moves. This will continue through all sections until the smallest section completes its stroke. COMMON USES FOR TELESCOPIC HYDRAULIC CYLINDERS Telescopic hydraulic cylinders are suited to applications where force space is limited and a traditional w

  EN24 AISI4340 steel is a medium carbon, low alloy steel know for its toughness and strength in generally grade. EN24 can be heat treated to a wide range of tensile strengths from 850-1000 N/mm² (‘T’ condition) up to 1550 N/mm² (‘Z’ condition). Heat treated EN24 offers high tensile strength combined with good ductility and resistance to shock. At low temperatures good impact values can be obtained. In this blog we explain a little about the characteristics and history of this well established steel grade. EN24 steel properties When used for applications in its heat treated condition EN24T combines high tensile strength with shock resistance. It is easy to work and can be forged or stamped without difficulty. EN24 is machinable in the annealed condition or when hardened and tempered. THE APPLICATIONS OF EN24 AISI4340 STEEL  EN24 steel was classified as a wrought steel for automobiles and aircrafts and as such was used to produce numerous parts and components for these industries. It is

  H8 Cylinder Tube   is a type of cylinder barrel tubes made of high precision steel pipe by cold drawing or hot rolling, usually with steel grade ST52, in accordance with   DIN 2391 honed   with ISO-tolerance range H8 on the internal diameter. ST52 Cylinder Tube is suitable for a variety of hydraulic cylinders,where tight tolerances and smooth surface finishing are critical factors. It is the basic material for manufacturing hydraulic cylinders particularly suitable for the industrial, mobile and special applications sector. Wuxi YUTONG produce H8 cylinder tube with two kinds of production process. honing or skiving / roller brunished to tolerance H8 – H10 (as per request) TECHNICAL CHARACTERISTICS OF H8 CYLINDER TUBE Material: E355+SR / ST. 52.0 (1.0580) Tolerance OD: EN 10305-1 en EN 10305-2 Tolerance ID: honed or  skived & roller burnished  to tolerance H8 – H10 Roughness: Ra max 0.4 µm Straightness: Max.  0.5/1000mm Wall thickness Tolerance: max. +/- 10% Length: in random leng
