Shock absorber resists corrosion

Hoerbiger-Origa has expanded its range of miniature industrial shock absorbers or linear decelerators, with 38 versions of a corrosion-resistant model called Armor Line.

Hoerbiger-Origa has expanded its range of miniature industrial shock absorbers or linear decelerators, with 38 versions of a corrosion-resistant model called Armor Line.

A thin dense chrome plating that nodularly adheres to the high strength steel body of the absorber creates the corrosion resistance.

This is guaranteed to be of even thickness even in the valleys and peaks of the threaded body and cannot delaminate to compromise performance.

Complying with military specification, Hoerbiger-Origa Armor Line shock absorbers are ideal for use in industries such as food, pharmaceuticals, medical, electronics, aerospace, clean rooms, automotive, and nuclear.

The range encompasses 10 sizes, with effective weight capacities from 2 to 2000kg.

The internal shock absorbing mechanism is available in either adjustable or fixed format, while the body is externally threaded along it whole length for ease of installation.

Hoerbiger-Origa has ensured that Armor Line is dimensionally equivalent to its other Shock Absorbers, so that direct replacement is possible.

In all applications they will reduce maintenance and replacement costs and increase service life.

A shock absorber works by converting the kinetic energy of a moving machine part into heat energy and dissipating this into the surrounding atmosphere.

It does this smoothly over the few milliseconds it takes to stop a machine axis or other load; thus shock load and vibration are avoided.

This is achieved because the shock absorber has a series of orifices down the length of an inner tube through which a piston travels.

At first, all orifices are open giving a large flow at relatively low pressure; but as the piston advances it progressively closes off more and more holes so the pressure (which is in effect the shock load) remains almost constant.

All shock absorbers from Hoerbiger-Origa are designed to give optimum performance in all applications.

They are manufactured using the highest quality materials and utilise key design features to ensure long trouble free life, these include: a one-piece piston and rod made from high-grade steel, hardened and heavy chrome plated for maximum wear resistance; an extra-large-diameter piston rod for superior strength; positive check valve for efficient oil flow and smooth operation; an extra-long neck bearing for maximum support and side load capability; and a high-pressure inner tube made from the highest grade carbon steel and heat treated for maximum strength.
