Critical sealing components in hydraulic rams that prevent fluid leakage and maintain pressure integrity.
Piston seals and rod seals are precision-engineered sealing elements in hydraulic ram assemblies. Piston seals are located on the piston head to prevent fluid bypass between pressure chambers during reciprocation, while rod seals are positioned at the cylinder head to contain hydraulic fluid and exclude contaminants from the rod gland area. These components ensure efficient energy transfer, maintain system pressure, and protect hydraulic fluid from contamination.

Piston seals prevent fluid transfer between pressure chambers on the piston, while rod seals contain fluid in the cylinder and exclude contaminants at the rod gland. They serve different locations and functions within the hydraulic ram assembly.
Replacement intervals depend on operating conditions, but typically range from 5,000 to 20,000 hours. Signs of leakage, increased friction, or visible wear indicate immediate replacement is needed.
Yes, but compatibility with hydraulic fluid and operating conditions must be verified. Common combinations include PU piston seals with FKM rod seals for balanced performance in demanding applications.
