Shock Gas Bladder

Knapsack shock absorbers sometimes have an internal floating piston for separating oil and gas. But more commonly, a rubber air-cooled storage tank that holds the gas separately. This air-free tank is less prone to air leakage than the sealing of the separation piston.
Main Feature:
Ensure oil and gas separation to avoid foaming; Actively prevent cavitation, improve the overall impact performance;
Provides consistent damping for optimal traction and control; Helps to extend the service life of the shock absorber
