N4M Backup Ring – High-Strength Anti-Extrusion Support Ring for Heavy-Duty Hydraulic Sealing Systems.
N4M high-strength backup ring for heavy-duty hydraulic seals. Anti-extrusion, load-bearing support, low friction. Reinforced polymer, –45°C~120°C, ≤60 MPa.
N4M Backup Ring – A high-strength anti-extrusion support ring engineered to protect hydraulic seals from gap extrusion under extreme pressures and side-load conditions. This heavy-duty backup ring provides rigid support to the primary seal, preventing deformation and maintaining sealing integrity during pressure spikes and shock loading. The precision-machined profile ensures consistent gap coverage and axial positioning, while the low-friction surface reduces wear on adjacent hardware and minimizes assembly drag. The advanced reinforced polymer compound delivers exceptional dimensional stability, chemical resistance, and load-bearing capacity across a wide temperature range. This sealing system support ring is ideal for heavy-duty hydraulic cylinders, piston/rod assemblies, high-pressure manifolds, and demanding industrial applications requiring reliable anti-extrusion protection and load distribution. Material: high-strength reinforced polymer or PTFE compound. Temp: –45°C to +120°C. Pressure: up to 60 MPa.
