Description
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.
The Hunger bearing rings can be used as single rings
or multiple rings arranged adjacent to each other. The
number of bearing rings depends on the expected side
loads. The butt joints in adjacent bearings should be
staggered.
