C67500 Manganese Bronze Bushing
C67500 Manganese Bronze Bushing
Self-lubricating bronze bearings are engineered for applications where external lubrication is impractical. Solid lubricants are compressed and molded directly into the bearing to guarantee a maintenance-free product. No additional lubrication is necessary.
C67500 Manganese Bronze Bushing Self-Lubricating Bearing: Engineered for Extreme Loads & Harsh Environments
C67500 Manganese Bronze is a high-strength, wrought copper-zinc alloy, often referred to as a high-tensile brass. Its unique composition, which includes significant amounts of manganese, iron, and aluminum, gives it a remarkable combination of mechanical strength, wear resistance, and corrosion resistance. This makes it an ideal material for manufacturing robust and durable self-lubricating bushings designed to excel in demanding industrial applications.
Unlike standard cast bronzes, the wrought nature of C67500 provides a more refined grain structure, resulting in superior mechanical properties and fatigue resistance. This makes it a reliable choice for components subjected to high stress, heavy loads, and harsh operating conditions.

Material Deep Dive: Why Choose C67500 Manganese Bronze?
C67500 Manganese Bronze stands out from other bearing materials due to its unique metallurgical properties, which are a direct result of its carefully balanced alloy composition.
•High Strength and Hardness: The addition of manganese and iron to the copper-zinc base creates a multiphase microstructure. These elements form hard, intermetallic compounds that are finely dispersed throughout the softer, more ductile matrix. This composite-like structure is the key to C67500’s impressive strength and hardness, allowing it to withstand extremely high pressures and loads without deforming.
•Exceptional Wear Resistance: The hard phases within the alloy’s structure provide excellent resistance to both abrasive and adhesive wear. This makes C67500 bushings highly durable, even in environments contaminated with abrasive particles like dust, dirt, and grit, significantly extending the service life of your equipment.
•Impact and Fatigue Resistance: The inherent toughness of the copper-based matrix allows C67500 to absorb significant impact energy without fracturing. This makes it an ideal choice for applications with high shock loads and frequent start-stop cycles, where other materials might fail due to fatigue.

As the table shows, C67500 offers a superior combination of strength and hardness compared to the more common C93200 bearing bronze. While C95400 aluminum bronze provides excellent corrosion resistance, C67500 often presents a better balance of overall performance, especially when considering its good machinability and cost-effectiveness.
Ideal Applications for C67500 Bushings
The robust properties of C67500 make it the material of choice for a wide range of demanding applications across various industries:
- Construction & Heavy Equipment: In excavators, loaders, and bulldozers, C67500 bushings are used in pivot points, kingpins, and hydraulic cylinder components, where they withstand high shock loads and abrasive conditions.
- Mining & Quarrying: For crushers, grinders, and other processing equipment, C67500 provides the necessary durability to handle extreme pressures and the abrasive nature of rock and ore.
- Industrial Machinery: In steel mills, stamping presses, and injection molding machines, C67500 bushings are used in high-load, slow-moving applications where reliability is paramount.
- Marine & Offshore: The good corrosion resistance of C67500 makes it suitable for rudder bearings, pintle bushings, and other components on ships and offshore platforms exposed to saltwater environments.
Beyond the Material: Customization and Value-Added Services
While the inherent properties of C67500 are impressive, its performance can be further enhanced through our expert manufacturing and customization services.
