OEM Cross-Reference — 6815119 & 6814882

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.

Customer Reviews

★★★★★United StatesPerfect fit, no issues

Picked up two of these for a Bobcat 331 we run on a landscaping site. Bolted straight in, no fuss. Three months of daily use and the seals are still holding — honestly didn't expect that at this price point compared to going OEM.

★★★★★Japan品質が良く、すぐに取り付けできました

Bobcat X331 用に2本注文しました。完全にピッタリ、取り付けもスムーズ。紛正品と比べても品質は全く問題なく、シールの状態も良好です。また飲みます。

(Ordered 2 for a Bobcat X331. Fit perfectly, went in without any trouble. Quality holds up well against OEM — seals are fine. Will order again.)

How It's Made

Each roller starts as a forged steel blank — not cast, not welded together. After turning, the tread goes through induction hardening to build up surface toughness where it actually contacts the track links. The floating seal faces get lapped flat before assembly, and every finished piece goes through a pressure test for oil retention. If it doesn't pass, it doesn't ship. Simple as that.

ShunQi Track mini excavator track roller manufacturing process forging induction hardening floating seal assembly
Forged blank → induction hardening → floating seal lapping → pressure test. Nothing leaves without passing the last step.

Why ShunQi Track

A bottom roller is a small part, but when the seal goes on a Bobcat 331 the whole machine stops — and waiting two weeks for a replacement is a real cost. We keep the 6815119 / 6814882 roller in stock and confirm fitment by OEM number or serial before the order goes through, so there are no surprises at the other end. The one-year warranty covers seal failure and tread defects; if something's wrong, send photos and we sort it out.

Before You Order

  • Check the machine plate — confirm the exact sub-model: 331, X331, 325, X325, X328, X334, X335, X341, 225, X231, 425, 430, E26, E32, E35, E42, or Hanxi H30. The series alone isn't always enough.

  • Find the part number — 6815119 or 6814882, either in your parts manual or stamped on the roller body. Both are valid.

  • Measure the shaft hole — this roller is M20×2. Takes 30 seconds with a thread gauge and saves a return shipment.

  • Decide on quantity — single replacement or a full set per side; both are fine, just let us know so we can pack accordingly.

  • Number worn off? — happens all the time. A photo of the old roller next to the machine plate is enough for us to confirm the right part.

Packaging & Delivery

Each roller goes out wrapped in rust-inhibiting film inside a carton box. For bulk orders, multiple units get palletized for container loading — FCL from Xiamen or Guangzhou is typically 7–15 days to most ports, LCL around 25–35 days. If you need a single piece urgently, DHL or FedEx gets it to your door in 5–7 days.
