4. FAQ
Q: What is this piston seal ring used for?
A:This is a high‑performance piston seal ring, installed on the piston inside a hydraulic cylinder. Its main job is to create a tight, pressure‑holding seal between the piston and the cylinder bore, preventing high‑pressure fluid from leaking past the piston. This ensures the cylinder maintains full pressure, delivering consistent force and preventing power loss from internal bypass.
Q:How do these materials perform in different conditions?
A:Standard PU piston seals work well from -30°C to +100°C and handle pressures up to 400 bar, making them ideal for most construction and industrial machinery. They have good compatibility with mineral‑based hydraulic oils. Filled PTFE versions can handle higher temperatures (up to 150°C) and pressures, with much lower friction, making them great for smooth‑moving or high‑efficiency applications.
Q:How long does this type of piston seal ring typically last?
A:Under normal operating conditions with clean fluid and proper installation, a PU piston seal ring like this usually lasts between 3,000 and 6,000 operating hours. In heavy‑duty or high‑temperature applications, it may need replacement sooner, but with regular fluid maintenance and correct installation, you can expect reliable performance for a long time.
