Product Description
EN10305-2 E355 Cold Drawn Welded Precision Shock Absorber Steel Tubes
The working cylinder and liquid storage cylinder of double cylinder hydraulic shock absorbers are manufactured from precision steel tubing, while installation rings utilize seamless finish rolling pipe. These components are critical for shock absorber performance and are the preferred choice for achieving shock absorber lightweighting.
Shock Absorber Types and Applications
- Standard Shock: Oil-filled design without special features, lasting up to 100,000 miles. Typically offered by OE manufacturers.
- Gas Shock: Common in smaller vehicles, uses oil for cushioning with pressurized nitrogen gas to maintain cooler operation and prevent oil thinning or foaming.
- Overload Shock: Coil-over-shock design typically found in off-road vehicles with coil spring fitted around shock cylinder.
- Heavy-Duty Shock: Designed for trucks, vans, and passenger vehicles with larger loads. Features larger diameter, reinforced attachment points, and bigger center shaft for rugged use.
- Automatic Level Control Shock: Used in luxury vehicles with electrically operated air pump activated by suspension sensors for added load compensation.
- Air Shock: Aftermarket shock absorber for truck and van rear applications. Features air inlet for pressurization and vehicle height adjustment.
