Sumitomo SH Series Track roller SH120/SH200/SH260

Sumitomo SH Series Track Roller for Excavator Undercarriage Replacement

The Sumitomo SH Series Track Roller is a replacement undercarriage component for compatible Sumitomo crawler excavators. Installed along the lower track frame, the track roller supports the machine's weight and provides a rolling contact surface for the track chain as the excavator travels and performs earthmoving operations.

This product listing covers selected Sumitomo SH Series applications, including SH120, SH200, SH260, SH280, SH300 and SH340. For machinery parts distributors, excavator repair workshops and fleet maintenance teams, these model references provide a starting point for identifying the required replacement roller. The exact fitment must be confirmed against the machine version, original part number and undercarriage specifications.

When sourcing a replacement, buyers should check the roller's dimensions, flange configuration, mounting structure and compatibility with the existing track chain. Matching the correct component helps simplify installation planning and reduces the risk of ordering a roller that does not fit the intended excavator.

Sumitomo SH Series Track Roller Model Compatibility

The available product information identifies two groups of Sumitomo SH Series track roller applications. Use the following references to begin your parts identification process, then verify the exact configuration before ordering.

Important fitment note: The model groups above do not establish that one roller is interchangeable across all listed excavators. Different machine versions may use different undercarriage configurations. Confirm the applicable part reference and dimensions for your specific machine before placing an order.

How to Identify the Correct Sumitomo SH Track Roller

Accurate component identification is essential when purchasing replacement rollers for excavator maintenance or aftermarket parts distribution. In addition to the machine model, several technical details should be checked to establish compatibility.

1. Machine Model and Original Part Number

Start with the complete Sumitomo excavator model designation and serial number, where available. Check the original equipment parts catalog or existing maintenance records for the applicable track roller part number.

If the original reference is unavailable, provide photographs of the existing roller and the machine identification plate. These details can help narrow down the appropriate replacement, although final fitment should be verified before ordering.

2. Roller Dimensions and Mounting Structure

Compare the replacement roller with the original component using verified measurements or technical drawings. Depending on the specific design, important dimensions may include:

• Overall roller width and outer diameter.

• Mounting-hole spacing and installation dimensions.

• Shaft diameter and shaft configuration.

• Flange dimensions and running-surface profile.

• Clearance requirements within the track frame.

These dimensions should be checked against the original specification rather than estimated from the model name. Even small differences in mounting geometry can affect installation and running alignment.

3. Single-Flange and Double-Flange Configurations

Track rollers may use different flange arrangements depending on the undercarriage design. Single-flange and double-flange rollers have different guiding profiles, so the required configuration must be confirmed before selecting a replacement.

When reviewing a Sumitomo SH Series track roller, compare the original component's flange arrangement, running surface and mounting structure. Do not assume that rollers with similar external dimensions are interchangeable without verifying the applicable specifications.

4. Sealing and Internal Construction

The internal shaft, bearing and sealing arrangement also matters when identifying a replacement roller. Sealing systems help protect internal components from dirt, water and other contaminants encountered during excavator operation.

Where the original design is uncertain, provide the existing part number, clear product photographs or technical drawings. These references are more reliable than assuming that similar-looking rollers share the same internal construction.

Track Roller Compatibility with the Sumitomo Undercarriage

A track roller works together with the track chain, track frame, front idler and drive sprocket. Checking these connected components during replacement helps identify potential fitment issues and abnormal wear that may affect the new roller.

Track Chain Contact and Running Alignment

The track roller supports the lower track chain as the excavator moves. Verify that the roller's running profile matches the intended track system and inspect the chain for uneven wear or abnormal contact patterns.

If the track chain also requires replacement, browse our Steel Track Chains range for additional model-specific options.

Track Frame and Mounting Points

Before installation, inspect the roller mounting area for damage, loose fasteners or alignment problems. Confirm that the replacement component matches the original mounting dimensions and that the installation follows the applicable equipment maintenance procedure.

Front Idler and Drive Sprocket Condition

The front idler guides the track assembly, while the drive sprocket transfers driving force to the track chain. Excessive wear in either component can contribute to abnormal track movement and uneven undercarriage wear. Inspect these parts alongside the track rollers when planning maintenance.

Common Track Roller Wear Conditions on Sumitomo Excavators

Track rollers experience repeated loading and contact during excavator operation. Ground conditions, machine usage, track adjustment and the condition of adjacent components can all influence their wear patterns.

• Uneven running-surface wear: May indicate abnormal contact, alignment problems or wear elsewhere in the undercarriage.

• Abnormal rotation or noise: May indicate internal wear, damage or a lubrication-related problem.

• Visible cracks or deformation: Require further inspection to determine whether the roller remains serviceable.

• Lubricant leakage: May indicate a sealing problem, depending on the roller's internal design.

• Repeated undercarriage wear: May warrant checking the track chain, idler, sprocket and track tension together.

Replacement decisions should be based on the actual condition of the roller and the applicable equipment manufacturer's service limits. Inspecting the surrounding components can help determine whether the problem is isolated to the roller or related to the wider undercarriage system.

Sumitomo Track Rollers for Parts Distributors and Repair Workshops

For construction machinery parts distributors, equipment repair businesses and fleet maintenance teams, correct parts identification helps simplify quotation preparation, purchasing and spare parts inventory management.

When requesting a quotation for a Sumitomo SH Series track roller, prepare the following information wherever available:

• Complete excavator model and serial number.

• Original OEM part number or existing supplier reference.

• Required quantity and intended replacement scope.

• Roller dimensions and flange configuration.

• Photographs of the original roller and its mounting arrangement.

• Technical drawings or dimensional measurements, if available.

• Destination country and shipping requirements.

For repeat purchasing or orders covering multiple excavators, a model-by-model parts list with confirmed part references can help reduce identification errors and support more consistent inventory planning.

If your required model is not clearly identified in the current listing, provide the available machine and component details for further review. You can also explore our complete Excavator Bottom Rollers category to find additional model-specific replacement options.

Frequently Asked Questions About Sumitomo SH Series Track Rollers

Which Sumitomo excavator models are covered by this listing?

The current listing references SH120, SH200, SH260, SH280, SH300 and SH340. These are model identification references rather than a guarantee of universal interchangeability. Confirm the precise machine version and applicable part number before ordering.

Can one track roller fit all Sumitomo SH Series excavators?

No such assumption should be made. Roller dimensions, mounting structures and flange configurations may differ between models and machine versions. Verify the original part number and technical specifications for the intended excavator.

How can I identify a replacement track roller without an OEM part number?

Provide the complete machine model, serial number if available, photographs of the existing roller and any known dimensions. These details can help with product identification, but compatibility should be confirmed before the order is placed.

Should I replace the track chain when replacing a track roller?

Not necessarily. The decision depends on the condition and measured wear of the existing chain and other undercarriage components. Inspect the chain, sprocket, idler and rollers together to determine whether additional replacement work is required.
