Viscoelastic Shock Absorbers
VS-BA5-FC Front Flange

Simple Design – High reliability

Energy capacity 221,269 in-lbs/Cycle to 1,327,613 in-lbs/Cycle
Stroke 4.13 in to 7.09 in

The self-adjusting Viscoelastic Shock Absorbers are designed on the principals of hydrostatic compression to combine the funtions of a shock absorber and a spring. The advantages are a high damping coefficient, a low sensitivity to temperature changes and increased security by integrated static preload.

Viscoelastic shock absorbers are being used across a wide range of applications within heavy industry. Examples include, Material Handling, Rolling Mills, Defense, Waterways and Paper production.

Mounting In any position

Positive stop Integrated

Material Outer body, Rod end button: steel painted grey; Piston rod: Zinc plated steel

Damping medium Visco elastic fluid


The shock absorber can be pushed through its stroke. In creep speed conditions the shock absorber provides minimal resistance and there is no braking effect.
