5. FAQ
Q: Is this product fully compatible with original bulldozer parts?
A: Yes, all dimensions, roundness and assembly gaps are strictly manufactured according to OEM standards. It is a fully interchangeable replacement part. Workers can complete direct installation without cutting, grinding or any other secondary processing.
Q: What matters need attention during disassembly and installation?
A: Before installation, please thoroughly clean the mounting groove, shaft surface and remove all residual old seal fragments and dirt. Do not strike the metal sealing surface with hard tools to avoid scratches. When installing rubber rings, keep them in a natural state without twisting or excessive stretching. After assembly, rotate the roller manually and check for oil seepage and abnormal noise.
Q: How does this seal perform in typical bulldozer working environments?
A: Bulldozers often work on muddy soil and stony ground. This dual-structure floating seal forms a solid protective barrier. It can effectively block thick mud and hard particles from invading the interior. Even after working in harsh sites for a long time, it can still maintain stable sealing performance.
Q: Do you support separate sales of metal rings or rubber parts?
A: We mainly sell complete sets to ensure the matching precision and overall service life of the seal. If individual parts are accidentally damaged during use or installation, you can contact us with detailed specifications, and we can provide supporting single accessories.
Q: What problems will be caused by using low-quality floating oil seals?
A: Inferior products use poor raw materials. Metal parts wear quickly under friction and impact, while rubber parts easily lose elasticity and deform. Serious oil leakage will occur soon, leading to insufficient lubrication of bearings. External mud and sand will damage internal components, resulting in frequent equipment failure and increased maintenance costs.
Q: How do you pack the products to ensure safe transportation?
A: Each cast iron ring is coated with professional anti-rust grease and wrapped with moisture-proof paper. Rubber parts are sealed in independent dust-proof plastic bags. The whole set is placed in a rigid plastic box, then packed into thickened cartons with foam cushions to prevent collision, rust and extrusion damage during long-distance transportation.
Q: What are the core advantages of this product compared with similar products?
A: This product is customized for bulldozer undercarriage rollers, featuring excellent wear resistance and anti-compression performance. The matched materials have long service life and stable sealing effect. With OEM-level precision and affordable cost, it is a trustworthy replacement part for daily maintenance of Komatsu bulldozers.
