Viscoelastic Shock Absorbers
VS-BA1-FC Front Flange

Simple Design – High reliability

Energy capacity 1,000 Nm/Cycle to 14,000 Nm/Cycle
Stroke 12 mm to 80 mm

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.
