VS-BA1-FA rear flange

Viscoelastic Shock Absorbers – VS-BA1-FA Rear Flange

In environments where space is limited but performance cannot be compromised, the VS-BA1-FA Rear Flange viscoelastic shock absorbers provide the ideal solution. Designed for universal mounting and easy integration, this compact unit delivers excellent energy absorption in a wide range of industrial applications.

Built around the principles of hydrostatic compression, the damper unites the functionality of both a shock absorber and a spring. It is self-adjusting, maintenance-free, and features a high damping coefficient that ensures consistent performance even under challenging temperature fluctuations.

Precision Damping for Moderate Loads

With a stroke range of 12 mm to 80 mm and an energy capacity up to 14,000 Nm per cycle, the VS-BA1-FA is tailored for systems that demand precise, reliable energy management—without requiring bulky components.

The integrated static preload boosts safety and responsiveness, while the rear flange design provides flexibility for installation in systems where frontal mounting is not feasible.
