Hydraulic Cylinder Tubes and Piston Rods

Tubes for Hydraulic Cylinders manufacturing

The tube is one the most important elements in production of hydraulic cylinders. High precision of internal diameters is provided by the using several methods of mechanical processing, such as honing and skived roller burnishing. High precision and roughness of internal surface provides smooth movement of the piston with sealing elements and reduces wear of the working elements of the cylinder. Also, the tube should have enough strength, since it will be affected by the high pressure from inside. Standard tubes are produced from materials such as St52 BK+S and analogues, internal diameter tolerance is H8, roughness of internal surface Ra0.4 – Ra0.8 depending on the tube diameter. Chrome plating can be applied according to client’s requirements.

Piston Rod for Hydraulic Cylinders manufacturing

The piston rod – is another important component of the hydraulic cylinder and it is a chromed rod from the cold-rolled steel. It should be precise and very strong, since from one side it will be connected with a piston that moves the rod, and from another side (usually) it will be connected with the part of mechanism to which this movement should be transferred. The piston rod should be polished with very high requirements to the surface roughness, since it should provide reliable sealing and insure that no leakage of the hydraulic liquid would take place. Our standard piston rods are produced from the material steel 45 or analogues, with tolerance f7 and chrome plating 20-25 micron. Hardness of the chrome plated level is 850-1000 HV, piston rod surface roughness Ra 0.2

The company Eurobalt Engineering can supply tubes and piston rods already machined, to reduce the time and efforts spent by the customer for machining operations in-house, allowing to concentrate on the assembly to increase amount of finished hydraulic cylinders. For that we require drawings and technical specification. So, tubes and piston rods can be delivered not only as raw material according to standards of industry, but also with machining so they could be used as parts for assembly (tube can be machined and welded into cylinder housing, rod can be machined into piston rod).
