A shock absorber is essentially an oil pump, a device that smooth out the abrupt and rough push or shake and distributes it as kinetic energy. Landing gear is a part of the support systems for industrial equipment, and shock absorbers are essential in every motorcycle and automotive suspension. Shock absorbers are typically cylinders with a sliding piston that is cushioned by hydraulic fluid or air. Hydraulic Type, and Gas-filled Type are the product types of the automotive shock absorber. OEMs, and Aftermarket are the sales channel of the automotive shock absorber. Twin Tube Design, and Mono-Tube Design are the design types of the automotive shock absorber.
