The Heavy-Duty Wheel Loader Bushing is a custom-engineered, high-strength wear sleeve specifically designed for CAT Backhoe Loader models 426, 428, 422F, and 432E.
This bushing provides precise alignment and long-lasting wear protection for key pivot points—such as the boom, bucket, and link arms—that endure continuous high-load operations.
Each unit is precision-machined from high-grade alloy steel (45#, 40Cr, or 42CrMo) and undergoes quenching, tempering, and induction hardening, ensuring superior hardness, impact resistance, and structural integrity.
Custom sizes and material grades are available to match different CAT loader variants or operating conditions, making it ideal for both OEM replacement and aftermarket use.
Compatible with CAT Backhoe Loaders – Perfect fit for CAT 426, 428, 422F, 432E models.
Heavy-Duty Performance – Designed for high-impact, high-load pivot joints to ensure maximum durability and stability.
Customizable Design – Support for custom dimensions, materials, and surface treatments according to client specifications.
Advanced Heat Treatment – Quenched and tempered to achieve HRC 55–62, ensuring long service life under harsh conditions.
Strict Quality Control – Every step from raw material inspection to final measurement follows ISO-grade precision standards.
| Category | Available Options | Description |
|---|---|---|
| Material | 45# / 40Cr / 42CrMo | Select based on load and environment requirements |
| Surface Treatment | Phosphating / Nickel Plating / Black Oxide | For corrosion and wear resistance |
| Size Range | Ø30 mm – Ø220 mm | Custom sizes available upon request |
| Lubrication Design | Straight or Spiral Oil Grooves | Ensures smooth pin movement and longer lifespan |
| Marking & OEM Branding | Available | Laser engraving or logo stamping upon request |
This bushing is engineered for CAT backhoe loader linkage systems, particularly in high-load and high-wear joints, such as:
Boom-to-arm joints – Transfers main lifting forces
Arm-to-bucket linkage – Handles bucket rotation and heavy material impact
Cylinder base and rod ends – Supports oscillation and hydraulic movement
Loader frame joints – Reduces vibration and prevents structural wear
Its precision fit and hardened surface significantly extend service life and reduce maintenance downtime in demanding environments such as mining, construction, and road maintenance.

Our bushings are produced under a rigorous 18-step process, ensuring consistent performance and reliability:
Production planning based on customer needs
High-quality steel procurement
Raw material chemical & mechanical testing
Precise sawing and shaping
5–12. Rough & precision machining, heat treatment, and 3D dimensional quality inspection
13–16. Surface treatment, coating inspection, and oil application for rust protection
17–18. Professional packaging and warehouse storage
Every stage follows ISO 9001 quality management with 100% traceable inspection records.
1. Can you produce bushings for other CAT or JCB backhoe models?
Yes. We can manufacture bushings for multiple loader brands such as JCB, Komatsu, Volvo, and LiuGong. Provide your drawing or sample, and we’ll match dimensions and materials precisely.
2. How do you ensure compatibility with CAT OEM dimensions?
We use CAT standard technical drawings and verify dimensions through three-coordinate measuring machines (CMM) during quality inspection to ensure accurate fitment.
3. What’s the difference between 45#, 40Cr, and 42CrMo materials?
45#: Economical, suitable for light to medium duty.
40Cr: Balanced strength and machinability for standard conditions.
42CrMo: Highest impact and fatigue resistance for heavy-duty use.
4. Can surface treatments be adjusted for different working conditions?
Yes. For wet or coastal environments, we recommend nickel plating.
For dusty construction or quarry sites, phosphating offers better wear resistance and oil retention.
5. What is your typical lead time for customized bushings?
Standard lead time is 15–25 days, depending on material and quantity.
We also support urgent orders with quick-turn production and priority shipment.
