HUNGER FAI BEARING RING

    FAI BEARING RING

    HUNGER bearing ring with wiping function type FAI is mainly used on piston rods. It allows space-saving construction (see page 24, example 1) due to its integrated wiping function. It provides guiding and bearing
    surfaces between rod and housing and prevents metal to metal contact between them.

    The HUNGER bearing ring FAI consists of an extremely abrasion-resistant and low friction POM-PTFE Bronze-Compound. It can be used for hydraulic oilwith a mineral oil base, for water-oil emulsions and for fire-resistant fluids as well as compressed air.

    It has a U-shaped cross-section and is split with an angled butt joint. It can be spirally compressed inwards
    for fitting into the rod housing where it springs back out into corresponding installation grooves. The bearing
    groove arrangement secures it against axial movement.
