Screen Isolation
The Schenck Enduro Spring
The Enduro spring consists of a steel spring core with a high carrying
capacity, covered with hot-vulcanised rubber. Eighty percent of the spring
effect, i.e. force transfer is ascribed to the steel spring. The aim of
the natural rubber sheath is to protect the steel spring against corrosion
and environmental effects.
The Enduro spring can be used wherever the springs are strongly affected
by corrosion. In addition, the rubber sheath offers protection against
the penetration of material between the coils of the spring. It also prevents
crushing between the spring coils. The consequent lack of stress concentration
results in a considerably longer life-span than for pure steel springs.
Typically, we have achieved in excess of six year’s life.
Besides this extended life, the Enduro spring effectively isolates vibration
in the same manner as steel coil springs, offering far better performance
in this regard than solid rubber buffers or other types of steel/rubber
combinations. The Enduro spring also has a shock absorber effect in that
it dramatically reduces screen jumping on start-up and shut down as the
screen travels through natural frequency ranges. Noise levels are significantly
decreased by the rubber isolation.

Since their introduction into Southern Africa in 2001, more
than 500 Enduro springs have been installed, without one reported failure.
On this basis, we can comfortably offer the units with a two year warranty
period. |
