5. FAQ

Q: What raw materials make up all sealing components inside this repair kit?
A: The full set consists of four specialized materials: cross-linked PU serving as primary dynamic seals, wollastonite mineral enhanced PTFE acting as pressure-resistant back-up rings, heat-resistant AEM rubber for static joint sealing, and mixed fiber phenolic composite fabric designed as wear-proof guide rings for reciprocating pistons.

Q: What natural color and surface feature does each component have without added pigment or coating?
A: Cross-linked PU seals present uniform pearl white with dense smooth texture; wollastonite-filled PTFE rings are pale gray with subtle mineral grain; AEM rubber parts are soft flax beige; mixed fiber guide fabrics take on natural chestnut brown with distinct woven texture.
Q: What core sealing function does cross-linked PU perform inside the bucket cylinder?

A: As the key dynamic sealing element, cross-linked PU possesses outstanding elasticity and pressure resistance. It fits tightly against the piston and cylinder groove, effectively blocking high-pressure hydraulic fluid leakage when the bucket performs continuous scooping, lifting and dumping movements while tackling hard rock and compacted ore in mining operations.

Q: Why is wollastonite-filled PTFE matched as the auxiliary back-up ring for PU main seals?
A: This modified PTFE can perfectly fill tiny gaps inside piston mounting grooves. When the bucket hits hard rock and creates instantaneous hydraulic pressure surges, it disperses excessive pressure and stops the PU sealing lip from being squeezed, distorted or ruptured, greatly enhancing the overall stability of the sealing system under impact loads.

Q: What performance strengths does AEM rubber have compared with ordinary rubber materials?
A: AEM rubber delivers superior resistance to long-term thermal aging and oil degradation. In the closed cylinder space where hydraulic oil keeps working at elevated temperatures for hours on end, it can maintain stable hardness and sealing performance without softening, hardening or swelling, ideal for high-temperature static connection positions.
