Shock absorbers: the final piece of the productivity puzzle

How do shock absorbers work?

Shock absorbers are most commonly seen and used in automotive vehicles but their presence is being increasingly seen on production lines across the world. These industrial shock absorbers are used as hydraulic machine
components for slowing down moving loads with minimal machine load.

Companies are striving to increase productivity by operating machinery at higher speeds, but this results in increased noise, damage to machinery, and excessive vibration. EEF, the manufacturers’ organisation, has
already called on the government to improve productivity, but raising productivity shouldn’t hinder the very machinery it needs to achieve it.

This is where shock absorbers come in; they are designed to improve product handling applications through smooth deceleration
and reduced maintenance. 

They work by providing controlled, predictable deceleration through converting kinetic energy to thermal energy. The motion applied to the piston of a hydraulic shock absorber, for example, pressurises the fluid and forces it to flow through
restricting orifices, thus causing the fluid to heat rapidly. 

This thermal energy is transferred to the cylinder body and dissipated to the surrounding atmosphere. For extra assistance, some production lines choose to air cool the absorber.
