The RunRight™ Rubber Suspension Unit DO-A has 4 bore holes in each of the inner squares. They are designed for transmitting alternating motions from the neutral position. A bolt through either two, or all four of the bore holes, can be used to mount a lever to either one or both sides of the unit. They are manufactured with cast iron or steel weldment housings and aluminum inner squares, see chart below. They have standard Tensys™ 10 rubber inserts and can be used for applications operating within a -40° to 180°F (-40° to 80°C) temperature range.

Note: Two RunRight DO-A elements can be used as highly dynamic spring accumulators, designed for feeder systems that operate near resonance frequency.
