This is a direct-fit aftermarket bottom roller for the Bobcat 331 and X331 — no drilling, no grinding, bolts straight onto the undercarriage frame. It also crosses over to the 200, 300 and 400 series and the E series; the full model list is in the table below. Both OEM numbers 6815119 and 6814882 refer to the same part — we cross-check against your machine serial before anything ships. M20×2 shaft, ships from Xiamen or Guangzhou, 1-year warranty included.

A quick note on the two numbers: 6815119 and 6814882 are both valid for this roller — same part, same shaft, same fit. Bobcat updated the part number at some point and both stayed in circulation, so whichever one you have in your parts book is fine. The compatibility runs across the 200, 300 and 400 series and the E series — details in the table.
