Excavator cylinder piston rod seals
Operating conditions:
Material: PTFE+NBR
Temperature: -40~110°C
Speed: =1.0m/s
Working pressure: ≤40mpa
Working medium: hydraulic oil
Design description:
The use of multiple SRS components in series can provide optimal sealing performance for high-speed applications; meanwhile, SRS is also commonly used
The flushing seal, integrated into the sealing system, counteracts high-frequency pressure and safeguards the primary seal.
SRS utilizes SAPPHIRE's high-performance PTFE filler material P4, which exhibits outstanding wear resistance and extrusion resistance
Widely applicable temperature range and medium.
This design also incorporates an O-ring elastomer for elastic compensation, compensating for machining tolerances and displacements.
Features:
Extremely small kinetic friction
Excellent extrusion resistance
Simple structure
Easy to install
