4. FAQ

Q: Could you introduce the materials adopted for different sealing components inside the kit and their respective features?
A: We adopt four kinds of high-performance materials for differentiated use. High-performance NBR is adopted for static sealing parts and O-rings thanks to its outstanding oil resistance. Wear-resistant PU serves as main dynamic seals and dust wipers. Filled PTFE acts as auxiliary back-up rings to resist high pressure and extrusion. Fabric-reinforced phenolic material is made into guide rings to share lateral load and reduce friction.

Q: What are the natural color and surface characteristics of each component without extra pigment or surface coating?
A: NBR rubber parts present uniform matte black with soft elastic texture. PU seals and wipers are deep black with smooth semi-gloss surface. Filled PTFE back-up rings are pale off-white with delicate fine texture. Fabric-reinforced guide rings are chestnut brown, and clear woven lines can be seen on the surface.

Q: What is the main working function of wear-resistant PU in the steering and lift cylinders?
A: As the core dynamic sealing component, PU features excellent anti-wear and anti-fatigue properties. When the cylinder drives the machine to complete steering, lifting and dumping actions repeatedly, it fits closely with moving parts to lock internal high-pressure hydraulic fluid firmly, and effectively stops oil leakage even under frequent reciprocating movement and variable load.

Q: What role do filled PTFE back-up rings play when matched with main sealing parts?
A: The modified PTFE material has enhanced rigidity and compression resistance. It can fill the tiny gaps inside piston mounting grooves perfectly. When the equipment makes sharp steering or bears sudden heavy load and causes instantaneous hydraulic pressure surge, it can buffer impact force and prevent the main seal lip from being squeezed, deformed or damaged, so as to stabilize the whole sealing system.

Q: What advantages does high-performance NBR have over ordinary rubber materials in practical application?
A: This upgraded NBR material has excellent long-term anti-oil and anti-aging capabilities. After long-term immersion in hydraulic oil and exposure to outdoor wind, sunlight and temperature changes, it can still maintain stable elasticity and sealing performance, and will not become hard, brittle or lose tightness easily in complex working environments.

Q: Where are the NBR rubber sealing parts mainly mounted on the hydraulic cylinder?
A: NBR components are mostly installed on static connection positions such as cylinder end cover flanges and hydraulic pipeline thread joints. These positions are in long-term contact with hydraulic oil and exposed to external dust and moisture, which can fully exert the superior comprehensive performance of NBR material.
