HUNGER FA BEARING RING

    FA BEARING RING

    The HUNGER bearing ring type FA is mainly used on pis-tons. It provides guiding and bearing surfaces between piston and cylinder tube and prevents metal to metal contact between them.

    The FA consists of an extremely abrasion-resistant and low-friction POM-PTFE-Bronze-Compound. It can be used for hydraulic oil with 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 easily expanded for fitting into corresponding installation grooves on the piston. The U-shaped groove arrangement secures the bearing against axial movement.
