description

Metal lock-type seal ring is static sealing part for planetary flange of final drive. It fills joint gap by precise cast iron fit, withstands pressure of transmission section, prevents gear oil leakage and stops sand and metal debris entering gear meshing zone. Deformation, notch, surface wear and crushing will lead to oil seepage. Continuous oil loss causes insufficient lubrication for planet gears and bearings, resulting in tooth breakage and seizure.

FAQ 

Q：Can slightly worn metal seal ring be reused?
A：Not recommended. Wear increases clearance, causes oil leakage and lets metal debris enter planetary gears.

Q：What happens if the ring is tilted during installation?
A：Uneven load leads to partial crushing and cracking, oil leakage occurs quickly.

Q：Can this metal lock ring be disassembled and reused?
A：Not recommended. Flatness is damaged after removal, sealing reliability drops.

Q：Will new seal work if flange surface is uneven?
A：Poor effect. Distorted flange creates local gap and re-leakage, repair flange surface first.
