Rod seal K35 70x85,1x6,3

The K35 rod seal, size 70×85,1×6,3 mm, made of PTFE and NBR. Designed for hydraulic cylinders as a piston rod seal. The design combines a PTFE sealing ring with an NBR energizing O-ring, which allows stable operation at high pressure and high speeds while maintaining low friction. Design features: gland profile for heavy-duty hydraulics, PTFE sealing ring with an NBR energizing O-ring, resistance to high pressures and dynamic loads, intended for applications requiring a low coefficient of friction. Technical parameters: Inner diameter d: 70 mm (≈ 2.76 in) Outer diameter D: 85,1 mm (≈ 3.35 in) Height H: 6,3 mm (≈ 0.25 in) Material: PTFE (sealing element) + NBR (energizing O-ring) Maximum pressure: up to 400 bar Operating speed: up to 5 m/s
