Construction of the cylinder piston seal
This is a compact seal combining several functions in a single unit. The outer polyurethane rings act as guides and supports, whilst the central rubber element ensures proper dynamic sealing. This design ensures stable piston operation under load, as well as resistance to abrasion and high operating pressure.
When to replace the piston seal
A worn cylinder piston seal manifests itself as the lift dropping spontaneously, a loss of lifting force, or oil leaks inside the cylinder. Regular replacement restores the system’s full sealing integrity and ensures safe operation of the equipment.
