OD Rod Seal
Descriptions
The single-acting rod sealing set profile OD consists of a PTFE rod sealing ring and
an elastomer O-ring as a preloading element. The asymmetrical cross-section of the
slipper ring is designed for best drag oil performance during stroke in both directions.
Optimal sealing performance will be obtained if the rod sealing set is used in tandem
with a double-wiper.
Profile OD is particularly suitable for sealing rods in control cylinders, servo-assisted
equipment, machine tools and quick acting cylinders. The sealing set is also suitable
for applications in the automotive (e.g. shock absorbers) and process industries.
The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes
this product suitable for a wide range of applications, especially for aggressive media
and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application profile.
Features
• Good sealing performance in extremely
small assembly conditions.
• Excellent wear resistance.
• Minimal break-away and dynamic friction and no stick-slip tendency ensures
uniform motion even at low speeds.
• Good energy efficiency due to low friction.
• Insensitive to pressure peaks.
• High temperature resistance assured by
suitable O-ring compound selection.
• High extrusion resistance.
• Adaptable to nearly all media thanks to
high chemical resistance of the sealing
ring and large O-ring compound selection.
• Dimensions according to ISO 7425-2.
• Also available as double-acting version.
• Short axial assembly length.
• Installation in closed and undercut
housings.
• Available in diameters from 4 to
3000 mm.
• Additional sizes of machined products
available on short notice.
