4. FAQ

Q: What kinds of materials make up the complete set of sealing accessories?
A: This kit adopts four practical composite materials: reinforced NBR for general static sealing, high toughness blended PU as main dynamic sealing parts, glass fiber filled PTFE as pressure-resistant auxiliary rings, and twisted yarn phenolic fabric specially made for piston guiding and wear reduction.

Q: What are the natural appearances and colors of each component without any additional paint or pigment?
A: Reinforced NBR parts are deep black with fine matte texture; blended PU seals present pale yellowish white and feel compact and solid; glass-filled PTFE rings are translucent off-white with tiny fiber texture; twisted yarn fabric guide rings are natural reddish brown with obvious woven lines.
Q: What is the primary working function of blended PU inside the dozer hydraulic cylinder?

A: As the core dynamic seal, blended PU features outstanding wear resistance and fatigue resistance. When the push blade rises, falls and pushes soil continuously, it closely fits the reciprocating parts to lock internal high-pressure hydraulic oil and avoid medium leakage under long-term alternating load.

Q: What advantages does glass-filled PTFE have when used with PU main seals?
A: Glass fiber enhances the rigidity and pressure resistance of PTFE. It fills the narrow gaps in installation grooves effectively. When the dozer bears sudden impact during pushing hard soil or rock piles, it can prevent the main PU seal from being extruded and damaged by instant pressure peaks.

Q: In what aspects is reinforced NBR superior to ordinary rubber materials?
A: Reinforced NBR is optimized for long-term oil immersion and outdoor aging. It can keep stable elasticity and sealing performance after being soaked in hydraulic oil for a long time, and will not harden or crack easily under wind, sun and temperature changes on open construction sites.

Q: Where are reinforced NBR seals mostly installed on the hydraulic cylinder?
A: They are mainly used for static sealing at cylinder end covers, flange joints and external oil pipe connectors. These fixed positions are exposed to oil and external environment for a long time, which can give full play to NBR’s oil-proof and weather-resistant properties.
