127-3807 Bottom Roller Assembly

Caterpillar® E70 series excavators come with a few undercarriage options. You might have a dedicated continuous rubber track, a steel track, or potentially even a hybrid-type steel chain with roadliner-type rubber pads directly attached to the chain. E70 series excavators typically use the same undercarriage drive parts regardless of which track type you are running. The bottom rollers are designed with inside guide-type and outside guide-type so that no matter which style track you are running, you will always keep your track rollers aligned with the guide system.

This is the replacement aftermarket bottom roller with the inside guide flange set up for the following Caterpillar® mini excavators:
