Shock Absorbers

Hydraulic shock absorbers and vibration isolators control shock and vibration in hydraulic systems. Shock absorbers absorb, convert, recycle, and dissipate energy. Also called dampers or dashpots, they are used with springs and cushions to absorb shock and prevent damage to equipment. They are used in automotive suspensions, airplane landing gear, and industrial machinery. Vibration isolators reduce noise and vibration caused by machines. They prevent damage to equipment and protect workers from loud, constant noise.
