17A5042110, 17A-50-42110 EQUALIZER BAR KOMATSU

The 17A5042110, 17A-50-42110 EQUALIZER BAR KOMATSU is a heavy-duty suspension and undercarriage component developed for large Komatsu crawler dozer applications. Online parts references and supplier listings most clearly associate this number with the Komatsu D155AX-6, while catalog data also links the same number to the D155A-6 suspension group.

From an engineering perspective, this component plays a major role in how a large dozer manages load transfer, frame movement, and track-frame balance over rough ground. In machines built for demanding dozing, ripping, and earthmoving work, the equalizer bar is not a cosmetic or secondary item. It is part of the structural system that helps the machine remain stable while working on uneven surfaces, compacted haul roads, quarry floors, and broken terrain.

The uploaded product images support that interpretation clearly. The part has a long reinforced beam shape, large machined end bores, a massive central body, and a finish intended for heavy-equipment service. The crate photos also show that this is a large structural component prepared for export handling rather than a small workshop consumable.

What this Komatsu equalizer bar does

An equalizer bar helps distribute load between the machine body and the undercarriage while allowing controlled movement as the tracks respond to uneven ground. On a large crawler dozer, that function is essential for balance, traction consistency, and chassis durability.

When a dozer travels across rock, hard-packed soil, slopes, or rough construction areas, the left and right sides of the undercarriage are exposed to different stress levels. A properly built equalizer bar helps manage those forces so the machine stays more stable and predictable during operation. That matters in daily field use because stability is directly connected to operator control, smoother travel, undercarriage protection, and more consistent pushing performance.

Komatsu’s D155AX-6 literature highlights the machine’s low-drive undercarriage and K-Bogie system, both of which are designed to improve traction, component durability, and operator comfort on uneven surfaces. That broader machine design explains why the equalizer-bar area is such an important zone in this model family.

Why this part matters in real working conditions

A crawler dozer works under repeated impact, vibration, twisting force, and weight transfer. Because of that, the equalizer bar must combine strength with precise fit at the pivot and bore areas. A weak or poorly machined part in this area can lead to alignment issues, accelerated wear, looseness, unstable undercarriage behavior, and a less controlled feel during operation.

That is why buyers searching for 17A-50-42110 or 17A5042110 are usually not only checking price. They are also checking whether the part is built for real field conditions, whether the machined areas are properly finished, and whether the supplier understands the seriousness of a large structural undercarriage component.

Based on the uploaded photos, this unit shows the visual characteristics expected from a heavy dozer suspension bar. The reinforced beam profile, large bore sections, and robust construction all point to a component designed for sustained structural load. The protective coating also supports better handling and presentation in storage and international shipment.

Product design features visible in the uploaded images

Reinforced beam construction

The main body has a strong elongated beam profile with recessed sections that reduce unnecessary bulk while maintaining rigidity. This kind of shape is common in components that must resist bending stress over time without compromising structural reliability.

Heavy-duty bore and pivot interfaces

The end sections are built around large machined openings and hardware interface zones. These areas are critical because they support the fit of mating components and influence how the assembly behaves under repeated motion and load.

Industrial protective finish

The yellow coating gives the part a clean heavy-equipment appearance and also helps protect the surface during storage, handling, and transport.

Export-ready crate packaging

The wooden crate images are valuable from a commercial point of view because they show that the part is packed for long-distance shipment. For international buyers, this adds confidence before purchase, especially when sourcing large structural components.

Confirmed and probable Komatsu applications

The clearest online fitment match I found is Komatsu D155AX-6. Multiple supplier and listing pages identify this equalizer bar number specifically with that model. A major parts catalog also places the same number in the D155A-6 suspension section and in the D155AX-6 equalizer-bar section.

Because Komatsu machines may vary by serial range, region, and configuration, final fitment should still be confirmed by machine serial number and current parts book before order placement.

Estimated weight in KG

Seller-listed item weight: 238.080 kg
Seller-listed shipping weight: 245.222 kg

This is the most specific published weight reference I found, but it appears on a reseller page rather than in an official Komatsu brochure, so it should be treated as a practical reference and confirmed before shipment booking.

Why buyers search this part in different number formats

Heavy machinery buyers rarely search one exact way. Some procurement teams use the hyphenated format from printed parts books. Others use the compact format copied from internal ERP systems, spreadsheets, warehouse records, or quotation software. That is why a strong product page should include both 17A-50-42110 and 17A5042110 naturally, without repeating the full exact-match keyword too often.

This improves discoverability for Google, AI-assisted search, internal site search, and B2B purchasing workflows. It also helps the page rank for broader phrases such as Komatsu D155AX-6 equalizer bar, Komatsu suspension bar, and undercarriage equalizer bar for D155 dozer applications.

Advantages of a well-made equalizer bar

A properly manufactured equalizer bar helps support:

Better undercarriage load distribution

More stable machine response on uneven ground

Stronger confidence during heavy pushing and ripping work

Reduced stress concentration in the suspension connection area

Better alignment and more dependable fit during installation

For maintenance teams, this means a part that supports both performance and durability. For fleet managers, it means a more reliable sourcing option for a highly important structural replacement item.

Why this product is valuable for export customers

Large dozer parts are usually purchased under time pressure. A machine may be down, a rebuild may be scheduled, or a site may be waiting for critical undercarriage work to be completed. In those cases, a buyer does not just need a part number. The buyer needs confidence in the supplier, packaging, application knowledge, and delivery process.

At 3GEN Export, we supply this part as an OEM supplier for heavy machinery spare parts, and we support customers worldwide with delivery in 5 working days. That message matters because the equalizer bar is a large, high-value item that is often ordered to solve an urgent operational need.

The crate images are especially useful for this reason. They show that the part is not only listed digitally but also physically prepared for shipment. For many international buyers, that is an important trust signal.
