Cat® Abrasion Undercarriage

Different By Design

You push through some of the most abrasive materials. That’s why Caterpillar has designed a new undercarriage that can take on abrasive applications with industry-leading low cost-per-hour performance. Cat® Abrasion is the newest addition to the Cat undercarriage portfolio. Each undercarriage is designed to meet specific application and machine requirements and deliver the industry’s lowest cost per hour. It is currently available on D3-D6 Dozer models. Key Benefits include:

  • Less Maintenance – Eliminates the need for bushing turns in abrasive applications
  • Lower Costs – Better sealability means less maintenance and reduced costs over the lifecycle
  • Extended Wear Life – Patented relieved tread idler design extends life up to 2x longer compared to traditional idlers
  • Smoother Ride – Eliminates contact between idlers and link rails providing a smoother ride for operators

Material Applications


A Lineup of Top Performers

*Manufacturing requirements include grade of material, heat treatment, form, fit, function and dimensional accuracy.

Innovative Improvements

Improved sealability combined with the proven wear life of rotating bushing technology means Cat Abrasion needs less time for maintenance and costs less to operate.

First-To-Market Cartridge Design

A – Tougher Thrust Ring Material- Resists chipping and cracking
B – Refined Seal Bore Geometry- Improves seal life in the harshest conditions
C – New Track Seal & Load Ring Design- Reduces packing and oil loss in freeze/thaw conditions
D – New Extended Life (XL) Coating- Reduces end grooving, corrosion and seal lip wear

Strong Support For Your Bottom Line

Louisiana Cat can help you manage your undercarriage for longer wear life and lower operating costs. Here’s how:

Caterpillar Undercarriage Assurance (UA) Program – Cat Abrasion offers leakage and breakage coverage for 4 years/6,000 hours, or 100% worn, whichever comes first.

Custom Track Service (CTS) Undercarriage Management – Used by Louisiana Cat undercarriage specialists, CTS offers customers an efficient inspection process for measuring and managing wear components, identifying equipment issues, predicting undercarriage wear-out timing and calculating cost per hour.

Parts Compatibility with Systemone™ – Parts are 100% interchangeable between Cat Abrasion and Systemone™ undercarriage. The only part number changes will be for the link assembly and track group.
