DescriptionMorgan ON profiles are double acting composite rod seals composed of a filled PTFE friction ring and pre-tightened rubber O-ring. They can be assembled in grooves according to standard ISO 7425/2. Option of connecting the seal to 1 or 2 back-up rings.Design standardThe design and apply please refers to Trelleborg's RG4, Parker's ON,B+L company's S55043and AS's XAB series standards. AdvantagesOptimal sealing in static and dynamic applications
Low friction coefficient; no stick-slip effect
Excellent abrasion and extrusion resistance
Wide temperature range and excellent chemical resistance, depending on the material selected for the O-ring Technical dataTemperature | -30°C/+200°C |
Pressure | 50 MPa |
Speed | 5 m/s |

ApplicationsFor reciprocated hydraulic system,
standard cylinders. Possessing excellent performance in high, medium and low pressure and in high load, high frequency conditions. Especially suitable for long stroke. Applied to bigger rod diameter in fluids and under high pressure, for example: bulldozers, excavators, forging machines, machines for pressing ceramic bricks, presses,rolling machinery, servo valves and other machine tools, etc. MaterialsFriction ringBronze-filled PTFE
