1. Project Overview
This project involves supplying a complete package of heavy-duty bearings and bushings for Caterpillar D9, D10, and D11 bulldozers operating in Saudi Arabia’s extreme desert and mining environments.
The client is a large equipment service provider based in Riyadh, servicing fleets used in oilfield construction and open-pit mining.
2. Challenges
Saudi Arabia’s climate brings several difficulties for heavy equipment maintenance:
Sand abrasion causing premature wear
High ambient temperature accelerating bearing fatigue
Continuous heavy-load pushing and ripping
Short downtime windows requiring fast delivery and high reliability
The client previously experienced frequent failures of aftermarket bushings and bearings, especially in the final drive, equalizer bar, and front idler assemblies of D9/D10/D11 bulldozers.
3. Our Technical Solution
To support the client’s CAT bulldozer fleet, we supplied a full range of compatible bearings and bushings, including:
🔧 For CAT D9
Final drive tapered roller bearings
Idler and track roller bearings
Swing frame & torque tube bushings
🔧 For CAT D10
Equalizer bar bushings
Suspension & main frame bushings
High-load cylindrical roller bearings
🔧 For CAT D11
Final drive bearing sets (high-load design)
Hard-chromed pivot bushings
Idler hub bushings with enhanced wear resistance
4. Engineering Advantages
Our components were engineered specifically for desert and mining conditions:
✔ Enhanced Heat Treatment
Improved hardness and core toughness to resist high-temperature fatigue.
✔ High-Chromium Surface Technology
Bushings gain superior resistance to sand abrasion and dry friction.
✔ Precision-Matched Dimensions
Every part matches OEM Caterpillar specifications and part numbers.
✔ Accelerated Production Cycle
We completed 52 SKUs and arranged shipment within 8 working days, reducing customer downtime.
5. Project Outcome
After installation and 6 months of operation:
Bearing temperature reduced by 12–15% under heavy load
Bushing wear rate decreased by over 30% compared with previous supplier
No premature failures reported
Customer extended the contract for year-round supply
Our parts are now used across three mining sites and two oilfield contractors
6. Client Testimonial
“These bearings and bushings are performing better than the aftermarket brands we tested before. The wear resistance is excellent, especially for the D11 final drive set. We will continue our cooperation.”
