The increasing globalization of industry drives demand for metric bronze bushings, mirroring the adoption of metric systems in overseas manufacturing. We offer a range of solutions to meet this growing need.

Determine your application’s specific requirements (load, speed, temperature, and environmental conditions) to select the appropriate metric bronze bushing. If standard sizes are unsuitable, our team provides custom-designed bushings tailored to your precise needs.

Metric vs. Imperial Bronze Bushings:

Metric bushings adhere to millimeter-based sizing, while imperial bushings follow inch-based standards.

• Design Compatibility: Metric bushings suit European and Asian machinery; imperial bushings are common in North America.
• Interchangeability: Direct substitution is rarely possible due to size discrepancies.
• Global Supply Chains: Many manufacturers produce both types for international clients.
• Engineers must verify system requirements to prevent mismatches during retrofits or repairs.

Metric bronze bushings, manufactured to precise ISO or DIN standards, ensure seamless integration with metric machinery. Key parameters include: Inner Diameter (ID) ranging from 3 mm to 300 mm with tight tolerances (e.g., H7 or H8) for shaft compatibility; Outer Diameter (OD) typically 1.2–1.5 times the ID for structural stability; customizable Length from 10 mm to 500 mm based on load and space; and optimized Wall Thickness, often 2–10 mm, for load distribution. Custom sizes are available for specialized applications, including heavy-duty industrial and compact automotive systems.

As sliding bearings, metric bronze bushings minimize friction, vibration, corrosion, and noise while simplifying maintenance and manufacturing. They act as a sacrificial wear component; by using a bushing, wear is concentrated on the easily replaceable bushing instead of the shaft or housing, reducing overall repair costs.

The main difference between metric bronze bushings and inch bronze bushings lies in the units of measurement used for their dimensions. As the names suggest, metric bronze bushings are sized using the metric system (millimeters), while inch bronze bushings are sized using the imperial system (inches).

Additionally, the manufacturing standards and specifications may also differ slightly between metric and inch bronze bushings. For example, the dimensional tolerances, surface finishes, and material grades may vary. This is why it is important to use the correct type of bushing for your application, as using the wrong type could result in poor performance or even failure of the system.

With both metric and imperial options available at Bronzeoilless.com, we can service a wider range of customers and ensure that we can provide the right type of bronze bushing for your specific needs, regardless of the unit of measure you use. This helps to increase efficiency and reduce confusion in the design and manufacturing process.

Metric bronze bushings are used in diesel engines, automobiles, agricultural machinery, hydraulic machinery, machine tools, forestry machinery, engineering machinery, mining, railroads, ships, petrochemical machinery, die-casting machines, metallurgical equipment; food packaging machinery, textiles, light industry machinery, aviation, weaponry, and other industries and sectors. The articulated parts consisting of metric bronze bushings are commonly used in excavators, loaders, bulldozers, cranes, boom concrete pumps, aerial work trucks, and other construction machinery.

They can operate over a broad range of temperatures and offer excellent load-carrying capabilities.

Choose Bronzeoilless.com to ensure that the bushings are made from high-quality materials and conform to the required specifications.

As a basic accessory, metric bronze bushings are used in a wide range of applications, from large industrial machinery to the smallest clocks and watches around us. We are surrounded by ubiquitous metric bronze bushing applications. How can we make high-quality bronze bushings, the first selection of material is an important factor.

If the load is large, and the speed is low usually choose aluminum bronze material, the load is general, the speed is generally usually used tin bronze material, the speed is fast and the load is not much can be lead bronze.

The specific alloy used for bronze bushings is often referred to as SAE 660 or CuSn7ZnPb, which conforms to international bronze standards. Some common alloys used for bronze bushings include:

CuSn7ZnPb: This alloy is a tin-bronze alloy with a composition of 7% tin, 1% zinc, and a balanced copper. It is commonly used for bushings in high-load, low-speed applications.

CUSN8/6.5: This alloy is a high-grade tin-bronze alloy with a composition of 8% tin and 6.5% zinc. It is suitable for applications that require high load-carrying capabilities and can withstand heavy loads.
