Kobelco SK200 Undercarriage Parts Guide
A model-specific sourcing guide for defining individual, one-side, full-machine and fleet undercarriage requirements.
Quick answer
For Kobelco SK200 undercarriage parts, send the complete SK200 model suffix and serial number, old references and clear photos. For chains and shoes, add link count, shoe width and available pitch data; for rollers and idlers, show flanges, bolt patterns and dimensions; for sprockets, show the tooth profile and mounting. State whether the order is one replacement, one-side set, full-machine set or planned stock.
Confirm the exact SK200 machine and track setup
SK200 generation, serial range and installed track configuration affect matching. Do not shorten the model designation or assume a previous replacement used the original factory specification.
Photograph the machine plate and both sides of the undercarriage, then link every requested part to an RFQ line.
- Full model suffix and machine serial
- Standard or special track configuration
- Old labels or casting references
- Left and right side condition
- Working environment and monthly hours
Record component-specific measurements
Track-chain requests benefit from link count, shoe width and pitch or old assembly reference. Roller and idler requests need mounting and flange evidence, while sprockets require bolt pattern and tooth profile.
Use measurements as supporting evidence and show the measuring tool in the photo. Do not replace a verified reference with an estimated dimension.
- Chain link count and shoe width
- Roller flange and mounting dimensions
- Idler tread and guide arrangement
- Sprocket holes and outside profile
- Track bolts, nuts and guard details
Match replacement scope to system wear
A new sprocket operating against a severely worn chain, or a new chain on worn rollers, may produce poor contact and shortened life. Review the system wear before selecting isolated replacements.
Separate urgent repair lines from matched-system replacement and reserve stock so the supplier can quote clear alternatives.
- Single failed part
- One-side matched set
- Complete-machine undercarriage
- Shoes and hardware assembly
- Project or fleet reserve quantity
SK200 matching information
| Requested part | Key data | System check |
|---|---|---|
| Track chain | Reference, link count, pitch and shoe width | Sprocket and bushing wear |
| Track/carrier roller | Position, flange and mounting details | Alignment, leakage and remaining rollers |
| Front idler | Reference, dimensions and guide profile | Recoil and track-tension condition |
| Sprocket/segments | Bolt pattern and tooth profile | Chain engagement and pitch wear |
| Track shoes | Width, hole pattern and quantity | Ground pressure and site application |
Buyer checklist before requesting a quote
- Complete SK200 identity is recorded
- Both track sides are photographed
- Chain, shoe and mounting data are measured
- Old references and casting marks are included
- Mating-component wear is reviewed
- Repair, set and stock quantities are separated
Frequently asked questions
Can SK200 parts be selected from the model name alone?
It is safer to include the full model suffix, serial number, old reference and configuration evidence.
Why check the sprocket when ordering a chain?
Chain and sprocket wear together; poor engagement can accelerate wear of a new component.
Should left and right quantities be listed separately?
Yes when the condition or replacement scope differs; otherwise clearly state one-side or full-machine sets.
