Fabric-reinforced seals series HSF
The HSF seal types consist of the HSF5, HSF6,
HSF7 and HSF8 solid seal styles and their split
versions HSF1, HSF2, HSF3 and HSF4. There
is also a pressure profile HSF9 in solid version
only. These seal styles are mainly used in
heavy-duty applications such as gear drives,
propeller shafts, cold and hot mill work rolls,
pumps, paper machinery, etc.
The HSF5, HSF6 and HSF7 are fabricreinforced
seals that have a strong, flexible,
textile rubber back instead of a metal case. The
HSF5 is the standard single lip rubber fabric
seal. The HSF6 adds radial lubrication grooves
in the back of the seal and the HSF7 adds a
circumferential lubrication groove. The HSF8
offers a dust-lip version of the standard seal.
To attain optimum sealing performance, a
retaining or cover plate is necessary to
properly install and apply all HSF seal types.
The plate creates an axial preload that ensures
reliable static sealing performance of the seal.
The plate should also be designed to avoid seal
distortion upon assembly. The HSF seal types
are available in NBR and FPM material.
Available HSF sizes can be found in the
product tables (page 246 to 277).
