Product Overview


Our OEM 9R0139 wheel loader bushing is a premium replacement part engineered for Caterpillar machinery, adhering strictly to original equipment manufacturer standards. It is compatible with a wide range of CAT models, including BACKHOE LOADERS (438, 416, 424D, etc.) and COMPACT WHEEL LOADERS (902, 908, 906). Crafted to deliver exceptional performance in heavy-duty operations, this bucket bush ensures precise fitment and seamless integration with loader systems, minimizing equipment downtime and maximizing productivity on construction sites.


Loader Bushing


Core Advantages


Superior Durability

Made from high-strength alloy steel, the bushing undergoes heat treatment and intermediate frequency induction quenching, achieving optimal inner and outer hardness. This enhances its crack resistance, enabling it to withstand extreme working conditions and extend service life significantly.


High Wear Resistance

Advanced material properties and heat treatment processes reduce wear between the bushing and pin shaft during frequent bucket loading and unloading, lowering part replacement frequency and operational costs.

Manufactured to CAT’s original specifications, the bushing guarantees perfect compatibility with target loader models, maintaining ideal clearance for smooth equipment operation after installation.


Strong Load-Bearing Capacity

As a critical construction machinery bushing component, it endures large radial and axial loads. Adapting to complex tasks like heavy-duty excavation and material handling.


Low Maintenance Cost

Some variants feature a self-lubricating design, reducing friction and eliminating the need for frequent lubrication. Special surface treatments such as phosphating also boost corrosion resistance, guarding against rain, soil, and oil erosion in harsh environments.


Application Scenarios


This high-performance loader bushing is ideal for construction, mining, and earthmoving projects. It is widely used in CAT backhoe loaders and compact wheel loaders, supporting heavy-duty operations such as excavation, material handling, and site leveling. Whether working in muddy construction sites, dusty mining areas, or rugged outdoor environments, our bushing maintains stable performance, making it a reliable choice for heavy equipment maintenance and upgrading.

Raw Material


The OEM 9R0139 bushing is primarily made of 45# steel, 40Cr alloy steel, and 42CrMo alloy steel, selected for their high strength and wear resistance. For precision components, we also use GCr15 high carbon chromium bearing steel, which offers excellent toughness and load-bearing capacity, suitable for high-speed and impact-load working conditions. All raw materials meet strict quality standards to ensure the final product’s reliability.


High carbon chromium bearing steel (fully quenched type) (GCr15): This material has high hardness, high wear resistance, and good toughness, and can withstand large loads and friction. It is suitable for manufacturing bearings and shaft sleeve parts that can withstand heavy loads, high speeds, and impact loads.
