| Brand | Type / Series / Model |
|---|---|
| JCB | Midi Excavators: 8080, 8085, JZ70, JS80, JS81 |
| HITACHI | EX60-5, EX75-3, EX75-5, HX180B, HX180B-2, ZR125HC, ZX70, ZX75, ZX80, ZX85 |
The list above is for reference. It is crucial to verify the OEM part number or roller dimensions.
Working on track undercarriages is extremely dangerous. Use extreme caution when releasing and tensioning tracks. Track tension must be released before service. The machine must be securely supported on certified stands. Never rely solely on the machine's own hydraulics.
Track rollers (bottom rollers) transfer the entire weight of the machine to the track chains and the ground. They are responsible for guiding the chain along the track frame and are subjected to constant high-impact loads and abrasion. Failure of one roller overloads the others and accelerates wear of the entire undercarriage.

Both rollers fit the same range of machines (JCB 8080, 8085, JZ70). The difference is their function: this product (JAA0011) is the bottom (track) roller, which carries the machine's weight. Part JAA0012 is the top (carrier) roller, which supports the top section of the track. They are not interchangeable.
2. Is this roller maintenance-free?Yes. KERTRACK rollers, like the genuine ones, are factory-filled with oil and equipped with durable, heavy-duty seals that provide lubrication for their entire service life. They do not require regular greasing.
3. Will this fit my JCB 8065?No. This roller is for the 8080/8085/JZ70 series. The 8065 machine uses a different bottom roller (part number 234/14800 or 332/U1381).
