Product Description

Products Introduction

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.
