OG Piston Seal

Descriptions

The single-acting piston sealing set profile OG consists of a PTFE piston 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.
Profile OG is particularly suitable for single-acting pistons in control cylinders, in servo
controlled systems, machine tools, quick acting cylinders.
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 7425-1.
• 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.
