Chrome Plated Bar/Piston Rod/LM Shaft

Chrome plated rod refers to the bar with a chromium layer with a hardness of up to 62HRC formed by electroplating on the surface. It is widely used in the automation industry and matched with the linear bearing (LM-OP). Therefore, chrome plated bar is also called piston rod or linear motion shaft (LM shaft) in many specific applications. The shaft can be divided into hard shaft and soft shaft according to different hardness.
