Self Lubricating Bronze Bushings Are Widely Used In Mining Machinery, Marine Machinery, Aviation, And Other Fields.

Mining machinery is often subjected to harsh production conditions and complex working conditions, which pose a great challenge for maintenance and servicing. In particular, articulated joints and rotary mechanisms, which cannot be lubricated regularly due to space constraints, often suffer from rapid wear or structural failure, failing coal mining machinery.

Self-lubricating bearings offer a new solution to the problem of poor lubrication in coal mines because of their high load-carrying capacity, adaptability to the environment, and maintenance-free performance.

The articulated lugs between the drill frame and the frame, and between the frame and the slide frame of the anchor digger are often subjected to frequent vibration and shock loads, and it is difficult to maintain and lubricate them due to space constraints, which often leads to the failure of the joint mechanism, resulting in the failure of some functions.

Costing Save & Long Life Spherical Plain Bearing

Therefore, the use of Spherical Plain Bearings at the articulated ears of coal mining machinery can not only extend the service life of the frame and trunnion but also achieve the purpose of reducing manpower and increasing efficiency.

The redirecting sprocket located in the transportation section of the anchor digger is used to change the direction of the scraper chain, and the copper sleeve of the redirecting sprocket will be worn severely after 30-60 d, but the wheel body is not worn.

• copper sleeve lubrication is not in place
• It is difficult to refill the lubricant.
• As the redirecting sprocket needs to rotate with the scraper chain movement, it is subjected to the cyclic impact of heavy load and low speed.
• The working space is limited, the environment is complicated, the operation is inconvenient, and regular maintenance cannot be guaranteed.

After the copper sleeve was finally changed from tin bronze material to inlaid graphite bearing with Gcr15 matrix, the life of the redirecting sprocket was extended from 30-60d to 210d without any failure.

1. Lubrication Mechanisms:
Self-lube bushings employ advanced lubrication mechanisms, such as solid lubricant films and oil-impregnated materials. These mechanisms ensure a consistent and reliable source of lubrication, eliminating the need for frequent manual interventions. In mining applications, where accessibility can be a challenge, this feature significantly reduces downtime and maintenance costs.

2. Material Durability:
Materials selected for self-lube bushings are chosen for their exceptional durability and resistance to wear. In mining environments where heavy loads and abrasive materials are commonplace, the robustness of these components becomes crucial. Self-lube bushings withstand the harsh conditions, ensuring a prolonged lifespan and minimizing the risk of premature failure.

3. Customization Options:
Manufacturers offer customization options for self-lube bushings, allowing mining companies to tailor the components to their specific equipment and operational requirements. This flexibility enhances the adaptability of these bushings to diverse mining setups, ensuring a precise fit and optimal performance.
