5. FAQ

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, adopting double-lip U-shaped integrated structure with smooth polished sealing surface. PU buffer rings are light orange with a 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 an outward dust scraping lip. Every accessory has unified standard dimensions, which can be quickly sorted and identified during on-site assembly without mixing up 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 the temperature range of -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.

Q: What hidden mechanical failures and economic losses will low-quality inferior seal kits cause to bulldozer steering hydraulic systems?
A: Cheap inferior seal kits use recycled ordinary waste rubber without PU buffer and PTFE anti-extrusion protective layers. They wear and age rapidly under frequent impact and vibration, resulting in serious internal and external oil leakage of the steering cylinder. The bulldozer will have slow steering response, inflexible turning and obvious jitter during walking operation. Worn rubber debris will scratch the piston rod and cylinder inner wall, bringing expensive metal component replacement costs, and long-term equipment shutdown will delay the overall construction progress and cause extra operation losses.

Q: What standardized installation operation specifications should maintenance technicians strictly follow to prolong the service life of this seal kit?
A: First, thoroughly clean the piston groove, cylinder inner wall and piston rod surface to remove old seal residues, metal burrs and accumulated oil dirt. Second, evenly coat all sealing parts with clean unused hydraulic oil for lubrication; thick grease is strictly forbidden to prevent rubber swelling and sealing failure. Third, install each seal in the correct direction, ensuring the sealing lip faces the high-pressure oil side. Fourth, lay the PTFE backup ring flat without warping before assembling the main oil seal. Fifth, after full assembly, run the steering cylinder at low pressure for 20 minutes to check all sealing positions for oil leakage before putting the whole machine into full-load construction work.
