Excavators encounter high pressure spikes and extreme mechanical loads that can cause seal extrusion. Extrusion-resistant seals are designed with back-up rings, harder durometer materials, and reinforced profiles to prevent deformation and failure. Seals using PTFE and reinforced polyurethane withstand dynamic forces and pressure surges effectively. This product provides robust sealing solutions for excavators operating in aggressive digging and lifting applications, reducing leakage and unplanned maintenance.
Seal extrusion is a major failure mode in high pressure excavator applications. It occurs when seals are forced into clearance gaps due to pressure spikes.
To combat this, extrusion-resistant seals use back-up rings, high-durometer materials, and reinforced designs that maintain shape under pressure. Materials like PTFE and PU are ideal for dynamic environments.
This product ensures reliable hydraulic sealing for excavators performing heavy-duty operations such as trenching and lifting.
