Rod Seals
Sealing ring: F-PTFE
Elastomer: NBR or FKM
Share:
Application Range
Used for hydraulic reciprocating motion environment and piston lever sealing under high, medium and low pressure, heavy-duty as well as high frequency working conditions; it can especially suitable for the occasions of long stroke, various liquids and high temperature occasions;it can be applied for larger piston clearance, for example it can be used for bulldozers, excavators, forging machines, ceramic brick press, rolling mills, servo valves and other machine tools.
Please refer to standards of RG4 series of Trelleborg Company, ON series of Parker Company and XAB series of AS Company when designing and selecting.
Features
Excellent static sealing performance
Allow for larger extrusion clearance, depending on the application occasions, and thus reduce processing costs
Owing to the larger extrusion clearance, it can be safely used in the Medium with sewage
Small friction with no crawling phenomenon
Simple groove, and can be used for integral piston
Since many kinds of materials can be adopted, it features strong adaptation to working conditions
Applicable to the latest environmentally-safe hydraulic oil(biological oil)
