Collection: Undercarriage Parts

Why the Undercarriage Matters for Your Fleet

The undercarriage system is more than just a frame. It is a complex assembly of moving parts. In fact, the undercarriage can account for a large portion of maintenance costs. It often reaches up to 50% of a machine's total maintenance costs over its lifetime.

When one component wears out, it puts stress on the rest of the system. For example, a worn sprocket will quickly damage a new track chain. That is why selecting the right supplier is critical. IMARA Engineering Supplies offers components built for demanding conditions. We serve the mining, construction, and earthmoving sectors.

Comprehensive Undercarriage Component Guide

To maintain machine stability, every part must work in perfect harmony. We supply a full suite of replacement parts for all major makes and models.

1. Heavy-Duty Track Rollers

Track rollers carry the weight of the machine while it travels. Our rollers are forged from high-strength steel. They feature advanced internal seals. These seals prevent leaks and keep lubrication in. This design ensures they can handle high-impact loads without seizing.

2. Precision-Engineered Idler Wheels

The idler’s job is to guide the track in and out of the rollers. It also helps maintain proper tension. Our idler wheels are heat-treated to resist wear. This prevents "flat spots" that cause vibration and noise during operation.

3. Reliable Track Adjusters

Correct track tension is vital for performance. If a track is too tight, it causes excessive wear. If it is too loose, it can jump off the machine. Our track adjusters use high-quality recoil springs. They provide consistent tension in rough terrain.

4. High-Performance Rubber Tracks

We offer premium rubber tracks for compact excavators. These are built with continuous steel cords. This design prevents stretching and snapping. Our rubber compounds are also tear-resistant. They are ideal for urban construction and landscaping.

5. Wear-Resistant Sprockets

The sprocket transfers power from the final drive to the track chain. These are high-friction parts. We use induction-hardening techniques to improve durability. This ensures the teeth maintain their shape and grip for a longer service life.

6. Final Drives and Travel Motors

The final drive is the heart of your machine’s movement. We provide complete travel motor assemblies. These units offer high torque and smooth power delivery. Every unit is tested for pressure and performance before it reaches your site.

7. Track Shoes and Track Chains

The track chain provides a flexible structure for movement. Our chains are available in "SALT" (Sealed and Lubricated Track) or dry types. We combine these with heavy-duty track shoes. This provides the ultimate "footprint" for stability on mud, rock, or sand.

Maximizing the Life of Your Undercarriage

Buying quality parts is the first step. The second step is proper maintenance. To get the most out of your investment, we recommend these best practices:

  • Clean the Undercarriage Daily: Mud and debris can harden around rollers. This increases friction and wear. A quick wash-down can save thousands in repairs.
  • Monitor Track Tension: Check your tension every 50 to 100 hours. Adjusting for specific ground conditions prevents unnecessary stress.
  • Limit High-Speed Travel: Excessive speed generates heat. Heat is the enemy of seals and lubricants. Move at a steady, moderate pace.
  • Avoid Unnecessary Reversing: Most undercarriages wear less when moving forward. Frequent high-speed reversing accelerates wear on bushings and sprockets.

Supporting Australia’s Construction and Mining Sectors

IMARA Engineering Supplies understands the local landscape. We support the heat of Western Australian mines. We also serve infrastructure projects in Sydney and Melbourne. Our parts are tested in real-world conditions.

We don’t just sell parts; we provide solutions. Our technical team helps you identify the exact part number. We use extensive databases to cross-reference OEM parts. This ensures a "first-time fit" every time you order.

Global Logistics and Fast Delivery

Downtime is expensive for any project. We have optimized our supply chain for speed. We ensure fast dispatch across Australia and international markets. Our logistics partners understand the urgency of "Machine Off Road" (MOR) situations. We work to get your components to the site as quickly as possible.
