SANY SY155U Excavator Parts

Part categories, compatibility checks and RFQ for the SANY SY155U.

SANY SY155U parts are for a short-tail mid-size excavator. The U suffix is the reason this page is separate from SY135C and any generic SY155 listing. Send the serial plate if you are choosing between those models.

Published NA figures: 16 t, Isuzu AR-4JJ1XASC, 77.5 kW, 5.47 m dig depth, reduced tail, 7 rollers, 600 mm steel shoes. Treat it as its own hub — not an SY135C with a shorter tail. Common systems: travel motors, controllers and undercarriage parts.

Published SY155U figures for parts ID

Reduced-radius tail is the identification tell. House and counterweight parts change versus the SY135C even when the engine family looks familiar.

Machine layout and typical work

SANY positions the SY155U for utility contractors working around buildings, traffic and other congested sites. The reduced-radius tail, backfill blade, auxiliary circuits and compact upper structure are the defining layout. House, counterweight, blade and attachment-hydraulic parts therefore deserve their own SY155U identification path rather than a generic 15-tonne search.

Parts and maintenance focus

Focus service on the Isuzu AR-4JJ1XASC engine, positive-flow hydraulics, high-flow auxiliary plumbing, travel and swing drives, blade group and 600 mm steel undercarriage. Typical requests include filters, hoses, coupler lines, pins, rollers and track components alongside travel motors, controllers and hydraulic repair parts.

What to verify before ordering

Record the full serial number, engine label, tail and blade configuration, track shoes or bolt-on pads, coupler and auxiliary options. For body and counterweight parts, include wide photos of the machine as well as the damaged area. For hydraulics or electrics, send tags, ports, connectors and monitor fault codes before a number is selected.

Compatibility

How to Confirm Compatibility

  1. Send the machine model exactly as it appears on the serial plate.
  2. Send the serial number and, if visible, the serial range or production year.
  3. Send the part number from the casting, tag or old invoice when you have one.
  4. If the number is missing, send clear photos of the part, ports, connectors and nameplate.
  5. We confirm fitment, tell you if a number is superseded, then send the quote and shipping options from the RFQ page.

FAQ

Parts Questions We Hear First

How do you confirm a part will fit?
We match the model, serial range and part number against supplier data and previous orders. When those do not agree, we ask for photos of the ports, connectors and nameplate — or use the part-number lookup and send an RFQ.
What if I do not have a part number?
Send the model, serial number and photos of the old part. We can often identify the number from the casting marks, connector layout or a superseded tag. The SANY parts catalog is the browsing path if you only know the machine type.
Do you supply genuine, OEM-sourced or aftermarket parts?
We quote the supply type we can actually deliver for that request. We do not call a part genuine or official unless the sourcing trail supports it.
Can you ship more than one model on the same order?
Yes. List every model and serial number. Mixed orders are common for fleets that run several SANY excavators.
Is every SY155U the same for parts?
No. Short-tail layout and serial updates both affect hydraulics and counterweight-related parts. We will not copy an SY135C or SY215C number onto an SY155U without a check.
