Viscoelastic Shock Absorbers – VS-BALR-FC Front Flange

When industrial systems encounter extreme force, only the most robust damping technology can provide the protection required. The VS-BALR-FC Front Flange shock absorbers from ACE are purpose-built to manage massive loads and long strokes in continuous, high-impact environments.

Designed using the principles of hydrostatic compression, these self-adjusting viscoelastic dampers combine the functionality of both a spring and a shock absorber—ensuring smooth energy absorption and controlled deceleration even under the harshest operating conditions.

Made for Demanding Industrial Applications

The VS-BALR-FC series is ideal for sectors where safety, durability, and performance are paramount. Applications range from heavy-duty material handling and steel rolling to military systems, lock gates, and paper production.

Thanks to their high damping coefficient and minimal sensitivity to temperature changes, these units perform reliably across a wide operating range. The integrated static preload boosts system safety from the start, while the maintenance-free design reduces long-term operational costs.

Trusted in Critical Environments

Whether absorbing energy in a steel mill or providing safety in defense systems, the VS-BALR-FC series ensures smooth deceleration, reduced wear, and superior operational longevity. Installation is simple, and the compact footprint makes it easy to retrofit into existing systems.

Note: These shock absorbers provide minimal resistance at creep speeds and offer no braking effect during slow movement.
