FlexiCase® rotary seals are designed to seal the most demanding rotary applications seals.
They feature an inner diameter lip that seals dynamically on a shaft and a metal
casing on the outer diameter to seal statically with a press-fit into a bore. A
gasket is positioned between layers of sealing lips and the casing to seal off
the potential leak path and to compensate for differential expansion. Usually,
FlexiCase® seals are not spring-energized. Consequently, the radial lip contact
forces are lower than those of rotary FlexiSeals®, which allows the seal to
function at much higher surface speeds.
Features/Benefits:
- Surface
speeds up to 70 meters/secon - Pressure
resistance up to 35 bar - Temperature
resistance from -100 °C to 250 °C and more - Diameters up to 2,000 mm
- Very
good chemical resistance thanks to PTFE sealing element - Low
frictional energy loss and friction-related heating - Unlimited
shelf life thanks to PTFE sealing elements - Long
seal life in dry and abrasive conditions (with wiper elements) - Single-
or double-acting operation - Uni-
or bi-directional rotation
Range of Application:
The combination of a robust metal casing with special PTFE compounds makes the
FlexiCase rotary seal suitable for use in conditions of extreme temperatures, surface
speeds and chemical attack, such as those typically occurring in compressors, special
pumps, hydraulic motors, etc.
