803164323 flange assembly for XCMG XP263S pneumatic-tyred roller

1. What is the main function of 803164323 flange assembly?
It is used for high-strength butt connection of transmission shafts, hubs and rotating components, ensuring coaxial alignment, bearing torque stably and reducing eccentric wear caused by offset.
What material and precision advantages does this flange assembly have?
2. It adopts forged alloy steel with high strength and toughness. Precision machining ensures strict concentricity and flatness, avoiding abnormal vibration and noise during high-speed rotation.
Can it be directly installed without calibration?
3. It is manufactured according to OEM matching data. The mounting holes, bolt distribution and positioning spigot are highly consistent with the original structure, allowing direct installation with no need for on-site adjustment.
4. What failures will be caused by worn or deformed flanges?
Damaged flanges will cause transmission runout, abnormal noise, increased vibration and accelerated wear of bearings. In severe cases, it will lead to loose connection and even transmission failure.
5. When should the flange assembly be replaced?
Replacement is required when the flange has obvious wear on the mating surface, deformation, cracked bolt holes, damaged sealing surface, or cannot maintain stable coaxial connection.
6. Is this assembly suitable for heavy-load and vibration working conditions?
Yes. It has high torsional strength and good fatigue resistance, specially designed for continuous compaction operation, not easy to deform or break under long-term stress.
7. How to properly maintain the flange assembly?
Keep the connecting surface clean and free of impurities; check bolt torque regularly to avoid loosening; prevent collision during disassembly; avoid rust and corrosion on the sealing and positioning areas.
