The new Tubus range of elastomer profile buffers from Ace Controls is
claimed to offer a much greater energy absorbing capacity than other
materials such as urethanes, rubber and spring steel. Elastomer buffers
have a respectable life expectancy of up to one million cycles - twenty
times longer than that of urethane, ten times longer than rubber and five
times longer than steel springs.
Five models are available, each providing different stopping
characteristics across a broad energy range. Tubus diameters range from
20mm to 188mm, and body lengths are from 19mm to 252mm. With a maximum
energy absorption of 66%, these buffers are suitable for applications in
which a moving mass does not need to be decelerated to an exact datum
position, such as an emergency stop.
