Shock Absorber Piston Rod

Brief introduction

We are a manufacturer specializing in the production of our shock absorber piston rod, which is processed using a series of processes, including fine and precision cold drawing, thermal refining, high-frequency quenching, finish machining of CNC lathe, fine grinding with an imported centerless grinder, high-precision polishing and more.

Applications

The shock absorber piston rod is widely used in various types of automobile shock absorbers, motorcycle shock absorbers and power car shock absorbers. Customers can choose the suitable shock absorber piston according to their specific requirements. Technical specifications of thermal refining, high-frequency quenching, hard chrome plating and other processes can also be accommodated.

1. Automobile shock absorber piston rod

The automobile shock absorber piston rod is typically made from 45# or 35# steel. When high-frequency quenching ends, the piston rod is finish-machined and then ground by centerless grinder. Afterwards, it undergoes hard chrome plating that uses micro-cracks electroplating techniques, resulting in a plating hardness of HV800-1050. The thermal refining hardness, high-frequency quenching hardness and depth, and plating thickness can be completed according to customer request.

2. Motorcycle shock absorber piston rod

The motorcycle shock absorber piston rod typically made from 45# or 35# steel. When fine finishing ends, the piston rod is then ground by centerless grinder. Afterwards, it undergoes hard chrome plating that uses micro-cracks electroplating techniques, resulting in a plating hardness of HV800-1050. 

3. Power car shock absorber piston rod

The power car shock absorber piston rod usually is made of 40cr steel. When thermal refining ends, the piston rod is then quenched with high frequency. Afterwards, it undergoes hard chrome plating that adopts micro-cracks electroplating techniques, resulting in a plating hardness of HV800-1050. The thermal refining hardness, high-frequency quenching hardness and depth, and plating thickness can be completed according to customer request.
