Product Overview


The 9R0162 bucket bushing is a top-tier OEM replacement part engineered for CAT Wheel Loaders, delivering unmatched performance in heavy-duty material handling and excavation. As a direct substitute for Caterpillar’s original 9R0162 bushing, this component is designed to fit seamlessly into a wide range of Caterpillar BACKHOE LOADER models, including 424D, 426, 438, 416, and 436C. Its core purpose is to protect critical loader components by reducing friction, absorbing impact, and enhancing operational stability—making it an indispensable part for industries relying on reliable, long-lasting heavy machinery parts. Crafted with premium alloy steels and precision manufacturing, the 9R0162 bushing meets OEM-quality standards, ensuring compatibility and performance that rivals original Caterpillar components.


High Performance CAT Bucket Bushing 9R0162


Core Advantages


Friction & Wear Reduction for Component Longevity

The 9R0162 bushing acts as a protective barrier between the bucket ear and pin shaft, converting direct metal-to-metal friction into low-resistance friction between the bushing and pin. This design shields the inner surface of bucket ear holes from premature wear, significantly extending the service life of both the bucket and connecting components. The use of high-strength alloy steels and wear-resistant materials ensures the bushing itself withstands continuous use in abrasive conditions.


Impact Absorption for Heavy-Duty Operations

Loader operations such as heavy excavation and bulk material handling generate significant impact forces. The 9R0162 bucket bushing is engineered to absorb these impacts, minimizing stress on the bucket, arm, and pin shaft. This shock-absorbing capability reduces the risk of component damage, downtime, and costly repairs—critical for maintaining productivity in high-intensity work environments.


Enhanced Operational Stability & Flexibility

Precision-engineered to maintain tight fit tolerances, the 9R0162 ensures accurate bucket connections, preventing excessive shaking or loosening during operation. This stability translates to smoother, more flexible bucket movements, enabling precise excavation and material handling. Whether navigating uneven terrain or lifting heavy loads, the bushing keeps the loader operating reliably, improving overall efficiency and safety.


Superior Sealing Performance to Prevent Contamination

Many 9R0162 bushings feature integrated sealing structures or are designed to work with seals, creating a barrier against dust, soil, moisture, and other contaminants. This prevents abrasive particles from entering the fitting gap, avoiding corrosion and wear on internal components. Additionally, the sealing design retains lubricating grease, enhancing lubrication efficiency and further extending the bushing’s service life.


OEM Compatibility & Customization Capabilities

As a genuine OEM replacement, the 9R0162 is 100% compatible with Caterpillar’s specified loader models. For unique requirements, we offer full customization services—simply provide design drawings or specifications, and our team will create bushings tailored to your machinery’s needs. This flexibility makes the 9R0162 suitable for both standard and specialized applications.


Application Scenarios


CAT Wheel Loader & BACKHOE LOADER Models

The 9R0162 is optimized for Caterpillar’s most popular loader models, including 424D, 426, 438, 416, 436C, 446B, 428, 424B, 420D, 442D, 430D, 432D, 436, 428D, 416C, 438C, 426C, 416D, 438D, 428C, 420F, and 430F. It is installed at key connection points, including bucket-arm joints and hinge points, where durability and precision are non-negotiable.

Raw Material


Premium Alloy Steels

The 9R0162 is manufactured using high-grade alloy steels, including 45# steel, 40Cr alloy steel, and 42CrMo steel—selected for their exceptional strength, toughness, and wear resistance. These materials undergo rigorous heat treatments (quenching, carburizing, tempering) to achieve a surface hardness of HRC58-62, enabling the bushing to withstand heavy loads and repeated impact without deformation.


Alloy Steel Characteristics

Alloy steel is formulated by adding chromium, nickel, and molybdenum to carbon steel, enhancing key properties:

Strength: Withstands higher loads than standard carbon steel, ideal for large loaders and high-intensity work.

Toughness: Resists cracking under impact, critical for heavy excavation tasks.

Wear Resistance: Maintains integrity in abrasive conditions, reducing replacement frequency.

Corrosion Resistance: Improved protection against moisture and contaminants, extending service life.

While alloy steel offers superior performance, our production process optimizes efficiency to keep costs competitive, ensuring value without compromising quality.

Production Process


Planning & Sourcing

Customer-Centric Planning: Develop production schedules aligned with client needs, including custom orders and bulk requirements.

Certified Material Sourcing: Procure alloy steels from trusted suppliers, with full traceability for quality control.

Raw Material Testing: Conduct chemical composition and mechanical property inspections to ensure compliance with OEM standards.


Machining & Forming

Precise Sawing: Cut raw steel into blanks with precise machining allowances, ensuring consistency in subsequent steps.

Quenching & Tempering: Heat treat blanks to enhance hardness and toughness, a critical step for impact resistance.

Rough Machining: Shape the bushing’s outer and inner dimensions, leaving minimal allowance for precision finishing.

Fitter Work: Mill, drill, and tap features such as oil grooves and mounting points, ensuring compatibility with seals and pin shafts.


Precision Finishing & Quality Assurance

Grinding & Polishing: Achieve tight dimensional tolerances (inner diameter H7, outer diameter js6) and smooth surface roughness.

Heat Treatment Validation: Test hardness (HB200-250 for copper alloy liners) and metallographic structure to confirm performance.

Surface Treatment: Apply galvanizing or chrome plating to enhance corrosion resistance; machine spiral oil grooves for improved lubrication.

Three-Coordinate Measurement: Verify key dimensions with precision tools, ensuring fit clearance of 0.03-0.08mm with pin shafts.


Final Inspection & Delivery

Cleaning & Oiling: Remove machining residues and apply anti-rust oil to protect against oxidation.

Comprehensive Quality Check: Inspect appearance, size, wear resistance, and sealing performance—rejecting any non-conforming units.

Protective Packaging: Package in moisture-proof, shock-resistant materials to prevent damage during shipping.

Global Shipping: Offer efficient international delivery, with tracking and timely updates for clients worldwide.
