Do you supply track rollers for Kato HD770 long arm excavators?
Expert Answer
Yes, VANROCK supplies track rollers for Kato HD770 long arm excavators through our appointed dealer network. For Kato undercarriage parts, we focus on matching the correct roller type and build to the machine’s undercarriage layout, since “long arm” configurations can still share or differ in roller arrangement depending on the exact HD770 version. We can also supply related undercarriage parts such as idlers, sprockets/segments, track chains, track shoes, and track bolts and nuts where needed. VANROCK is an independent manufacturer and is not affiliated with Kato. Pricing is provided on request only, and your dealer can help confirm the correct part using the machine model, serial number, and existing roller measurements if available.
