Description
Product overview
Gleitef KG is a double acting sealing element consisting of a machined PTFE sealing ring and an O-ring used as a preload element. It is an active sealing element: as system pressure increases, the load on the sealing edges increases. PTFE sealing elements are produced by machining and can be manufactured to fit specific installation spaces and diameters. PTFE compounds can be filled with bronze or carbon graphite to improve compressive strength. O-rings are available in a variety of elastomer materials. Typical applications include hydraulic and pneumatic cylinders, fittings, presses and machine tools.
Fields of application
Main use
Standard double acting piston/rod seal for hydraulic and pneumatic cylinders.
Materials
Elastomers, PTFE, PTFE with filling material (e.g. bronze, carbon graphite).
Technical values (summary)
Materials variants / Performance
Variant: NBR — Pressure: up to 40 MPa — Temperature: -30°C / +80°C (material dependent) — Speed: up to 10 m/s
Variant: FKM — Pressure: up to 40 MPa — Temperature: -20°C / +200°C (material dependent) — Speed: up to 10 m/s
Notes
Maximum values for temperature, speed and pressure are not simultaneously applicable and vary depending on material and media.
