XCMG YZ12JC / YZ14–18JC Roller Shock Absorber – YLJ-19C PN 801902820 (Old DWG 5012983) | OEM Rubber Mount

产品特点与应用

PN 801902820 / Model YLJ-19C​ (old drawing 5012983) is a XCMG-specified rubber shock absorber / vibration isolator​ for YZ-series road rollers (YZ12JC / YZ14JC / YZ16JC / YZ18JC). It's the elastic mount placed at the drum suspension interface — used to absorb vibration energy transmitted from the vibrating drum to the frame. As a rubber-bonded component, it's a wear-and-aging item rather than a structural part, typically replaced in sets during scheduled maintenance to keep vibration isolation performance within spec.
