4. FAQ

Q: Could you introduce the full material configuration and functional division of each part in the kit?
A: We adopt four professionally formulated materials for different working demands. Blended NBR is used for static sealing elements and all O-rings. Thermoplastic PU serves as primary dynamic seals and external dust scrapers. Glass-fiber reinforced PTFE acts as pressure-resistant auxiliary backup rings. Linen composite phenolic material is applied to produce guide rings for piston positioning and load bearing.

Q: What are the natural color and surface characteristics of each component without extra dyes or surface treatments?
A: Blended NBR parts are soft jet black with a fine matte finish and good resilience. Thermoplastic PU seals show pale amber tone with a compact and smooth surface. Glass-fiber reinforced PTFE rings are light gray with tiny visible fiber textures. Linen composite guide rings present natural taupe brown, with distinct woven textures across the surface.

Q: What unique performance does thermoplastic PU deliver in the excavator’s arm and bucket cylinders?
A: As the core dynamic sealing component, thermoplastic PU features outstanding flexibility and anti-fatigue performance. When the arm stretches and retracts and the bucket scoops and unloads materials repeatedly, it fits tightly with moving parts. It locks high-pressure hydraulic fluid steadily inside the cylinder and resists wear even under frequent reciprocating motion and variable working loads.

Q: What is the functional value of glass-fiber reinforced PTFE when paired with main PU seals?
A: Glass fiber greatly enhances the structural strength and anti-extrusion ability of PTFE. It fills the micro gaps inside piston mounting grooves perfectly. When the bucket strikes hard rock or compacted soil and creates sudden hydraulic pressure surges, it disperses instantaneous pressure effectively and prevents the PU seal lip from being squeezed, distorted or torn.

Q: What advantages does blended NBR have compared with conventional ordinary rubber?
A: This blended NBR is optimized for comprehensive outdoor use. It balances excellent oil resistance, moderate low-temperature flexibility and anti-aging performance. After long-term immersion in hydraulic oil and exposure to wind, dew and changing temperatures on open sites, it can still maintain stable elasticity and sealing tightness without hardening or shrinking.

Q: Where are the blended NBR sealing parts mainly installed on the hydraulic cylinder?
A: These rubber components are mostly arranged on fixed connecting positions, including cylinder end cover joints, flange surfaces and threaded ports of auxiliary hydraulic pipelines. These areas stay in long-term contact with hydraulic fluid and external air, making full use of NBR’s reliable static sealing performance.
