Graphite Inlaid Oilless Gunmetal Solid Lubricant Bearings, also known as Bronze Bushings with Normal Metric Sizes, are a type of bearing that incorporates graphite as a solid lubricant within the gunmetal material. These bearings are designed to operate without the need for external lubrication, making them ideal for applications where lubrication is difficult or impractical to maintain.

The graphite inlaid in the gunmetal provides a continuous and self-renewing lubricating film, which reduces friction and wear between the moving parts. This allows the bearings to operate smoothly and efficiently over extended periods, even in harsh or demanding environments.

Gunmetal, a type of bronze alloy, is known for its high strength, good wear resistance, and corrosion resistance. When combined with graphite, it creates a bearing material that is both durable and effective in reducing friction.

Bronze bushings, in general, are a type of sleeve bearing that are commonly used in various industrial and mechanical applications. They are typically press-fit or shrunk onto a shaft and are designed to support and guide radial and axial loads.

Normal metric bushings refer to bushings that are manufactured to standard metric dimensions, making them suitable for use in a wide range of metric-based machinery and equipment.

Overall, Graphite Inlaid Oilless Gunmetal Solid Lubricant Bearings with Normal Metric Bushings are a reliable and efficient choice for applications that require low-friction, low-maintenance bearings.

The oilless graphite plugged bronze bushing is widely used in continuous casting rolling machine, mining machinery, shipping machinery, turbine, injection machinery, auto mould and so on.

Oilless Bushing Benefits

• Maintenance free

Reduce the amount and frequency of lubrication or can be used without oil or grease.

• Eco-friendly

Protects the environment from oil contamination.

• Reduction of management costs

Reduces lube oil consumption and equipment maintenance costs and enables a significant reduction in operating costs.

• Corrosion resistance

It can be used in environments with corrosion, such as humid environments.

Low-maintenance – weather-resistant – cost-effective

Agricultural machinery like tractors requires robust and dependable bushing & bearing supports that are sufficiently protected against environmental conditions such as dirt, impacts, rocks, dryness, and moisture.
