Hard Chrome plated bars are generally produced from steel bars combining high strength with excellent machinability and weldability. Tolerance on bar diameter to ISO f7. Common applications are found in agricultural machinery, production equipment, cranes, garbage compactors, lifters etc.
Hard chrome plated rod. It is a kind of bar which surface is treated through special grinding and hard chrome electroplating. Linear shaft is widely used in the automatic transmission devices, such as robot, automatic observer, computer, precision printer, all kinds of air cylinder, hydro-cylinder, piston rod, packing, woodworking, spinning, printing and dyeing machines, die-casting machine, injection molding machine, other leader, mandril and so on. Meantime, due to its hardness, it can prolong the service life of common precision mechanical devices.
