Ameritool carbon steel gas springs offer optimum weight compensation and force support in lifting, moving and adjusting-type appli cations. Our wide range of standard product allows Ameritool to offer different strokes and force variations to meet all your application requirements. To obtain optimum service life of an Ameritool carbon steel gas spring, you should always mount the piston rod pointing down to ensure lubrication of the guide and seal system. Never apply a twisting or lateral force to the gas spring. Ameritool offers a series of mounting brackets to assist in limiting any undesirable twist or lateral forces.
