Hitachi KH180 Track Roller 9058157 for Crawler Crane Undercarriage
This Hitachi KH180 track roller is a replacement undercarriage part identified by OEM reference 9058157. It supports the lower track chain, distributes load across the crawler frame, and keeps the machine moving in a controlled path during lifting and travel.

Product Description
The Hitachi KH180 crane track roller sits on the lower side of the crawler frame and carries the operating load through the track chain. A worn or seized roller shows up as abnormal track movement, faster chain wear, or unstable travel — problems that get worse quickly if the roller is left in service past its wear limit.
SQ confirms each order against the actual machine model, old part photos, or measured dimensions before shipment. This step exists because the KH180 was produced across multiple versions — KH180, KH180-2, and KH180-3 — and roller dimensions are not always identical between them. Matching by model name alone is not enough to guarantee the part fits.
Why Roller Matching Matters
A roller that does not match the crawler frame contact surface causes uneven pressure and side wear. For KH180 machines, OEM reference 9058157 is a useful starting point, but physical dimensions should be checked when the machine has been repaired before or when the sub-version is unclear.
Sub-model check: Confirm KH180, KH180-2, or KH180-3 before ordering — roller width and shaft dimensions can differ.
Key measurements: Outer diameter, overall width, and shaft mounting distance are the three most important figures to verify.
Seal condition: If the old roller shows oil staining around the end caps, check the track frame groove before fitting a new roller — a worn groove damages new seals quickly.
Chain tension: Low track tension causes chain slap against the roller tread and shortens service life. Check the idler adjuster when replacing rollers.

The idler, carrier roller, and track shoes all wear at rates that depend on each other. Checking these parts at the same time as the roller saves a second disassembly later.

Quality Check and Export Packing
Each roller is checked for surface condition, dimensional accuracy, rotation smoothness, and seal integrity before packing. For sea freight, parts are greased against corrosion and packed in wooden cases or on pallets with clear model and quantity markings.
Frequently Asked Questions
The roller I removed does not match the 9058157 dimensions I found online — why?
This happens when the machine was previously repaired with a non-standard roller, or when the KH180 sub-version uses a slightly different frame specification. Measure the worn roller directly and send those figures alongside the OEM reference. SQ will cross-check both before confirming the replacement.
Is this an original Hitachi part?
No. This is a new aftermarket replacement part for compatible Hitachi KH180 crawler cranes. Hitachi model names and OEM references are used only to indicate machine fitment.
How do I confirm the correct roller before ordering?
Send photos of the old roller from both ends and the side profile, the machine sub-model (KH180, KH180-2, or KH180-3), outer diameter, overall width, and shaft mounting distance. SQ will verify fitment before sending a quotation.
Trademark notice: Hitachi, KH180 and related model designations are referenced solely to indicate equipment compatibility. This is an aftermarket replacement part supplied by PartsCrane / Quanzhou Shunqi Construction Machinery Parts Co., Ltd. It is not an original Hitachi product.
