The CR-II-3 is a shock absorbing caster specifically designed for equipment which must be protected from shock and vibration.  This unique design gives vertical deflection in response to a light load, but also provides protection against heavier shock loads.  If a unit is dropped or subjected to a sudden load, the caster will provide smooth shock absorption and will not suddenly hit bottom or abruptly come to the limit of its spring system.
