5. FAQ

Q: Please describe the appearance and structural characteristics in detail.
A: The alloy cast iron rings are light silver in color, with finely polished flat sealing surfaces that have no defects or burrs. The rubber components are deep black annular sleeves with even texture and moderate hardness. The whole product adopts a paired double-ring structure, with compact overall size and standard roundness, perfectly adapting to the narrow installation space of mini excavator track parts.

Q: Is this part interchangeable with the original factory component?
A: Yes. Every dimension, tolerance and assembly parameter strictly follows OEM standards. It is a direct replacement part, so technicians can finish installation directly without any cutting, polishing or other modifications.

Q: What precautions should be taken during installation and commissioning?
A: Before installation, thoroughly clean the mounting groove and shaft surface to remove dirt, old seal scraps and deteriorated oil. Do not use hard tools to hit the metal sealing surface to avoid scratches. Install the rubber sleeves in natural condition without twisting. After assembly, rotate the roller manually and check for oil leakage and abnormal noise.

Q: How is its comprehensive performance in complex working scenarios?
A: Mini excavators often operate on soft soil, muddy roads and scattered gravel ground. This dual-layer sealing structure can effectively block external impurities. Even working in wet and dusty conditions for a long time, it can still maintain stable sealing effect and will not fail easily.

Q: Is it available to purchase metal rings or rubber parts individually?
A: We mainly supply complete matched sets, because the two metal rings are precision paired to ensure sealing effect. If individual parts are damaged accidentally, you can send us specifications and we will provide corresponding separate accessories.

Q: What negative impacts will inferior floating oil seals bring to the equipment?
A: Inferior seals use low-grade raw materials. The metal parts wear quickly and the rubber loses elasticity in a short period. Oil leakage will happen frequently, resulting in dry friction of bearings. A large number of external impurities will enter the interior, causing serious component damage and affecting normal construction progress.

Q: What packaging solutions do you adopt for storage and transportation?
A: Each metal ring is coated with anti-rust oil and wrapped with waterproof paper. The rubber parts are sealed in independent plastic bags. The whole set is placed in a rigid plastic box, then put into cartons filled with foam. This multi-layer protection effectively prevents rust, collision and extrusion damage during delivery.
