5. FAQ

Q: What unique practical advantages does the four-material matching design bring to bulldozer tilt cylinder sealing?
A: Bulldozers work on rough earthmoving sites all year round, and the tilt cylinder bears frequent alternating impact loads and long-term continuous vibration, with obvious temperature differences between cold winter and hot summer. NBR main seals balance oil resistance and elastic recovery to stably block internal and external leakage of hydraulic oil. PU buffer rings absorb instantaneous hydraulic pressure spikes to avoid tearing damage to core sealing lips. FKM O-rings resist high temperature and oil aging, adapting to long-hour non-stop construction operation. PTFE flat rings reduce friction between metal contact surfaces and prevent seals from being squeezed and cracked under peak pressure, forming multi-layer anti-leakage protection structure to extend overall service life of the seal set.

Q: What color and structural appearance features do each component inside this seal kit have?
A: NBR main rod and piston oil seals are solid black with double-lip U-shaped integrated structure and smooth polished sealing surface. PU buffer rings are light orange with special tapered shock-absorbing outline. FKM O-rings are coffee brown with uniform round cross-section without deformation. Milky white thin PTFE backup rings have burr-free smooth edges. The dust wiper is black with outward dust scraping lip. Every accessory has unified standard dimensions, which can be quickly sorted and identified during on-site assembly without mixing different sizes.

Q: What stable working pressure and temperature range can this whole set of composite seals withstand?
A: This multi-material composite seal kit can continuously bear stable working pressure up to 400 bar. NBR and PU accessories work normally within -34°C ~ +120°C, while FKM O-rings can adapt to -25°C ~ +140°C. It can maintain reliable sealing performance in low-temperature mountain earthmoving construction in winter and long-hour full-load pushing operation in summer, without swelling, hardening, cracking or internal and external oil leakage failures.
