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.
Top rollers (carrier rollers) support the upper run of the track chain. They prevent the chain from sagging, striking the undercarriage frame, and reduce noise, vibration, and wear on the track links.

Both are top rollers for JCB midi excavators, but they fit different models. This roller (JAA0012) is specific to the 8080, 8085, and JZ70. The 332/U1415 roller is for the 8040-8065 range. They likely have different mounting dimensions or tread profiles and are not interchangeable.
2. Is this roller maintenance-free?Yes. GX-AFTER 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 top roller, part number 332/U1415 (or 234/14900).
