Graphite Embedded Bushing

Graphite-embedded bronze bearings are self-lubricating bearings made by opening holes of appropriate size and orderly arrangement on the metal friction surface of the bearing substrate and then embedding the formed solid lubricant with self-lubricating properties in the holes. It can be applied to a special environment that does not rely on oil film lubrication or less oil lubrication.

Spherical Oil-Less Bushing

The spherical oilless bushing comprises a high-quality low carbon steel base, a sintered spherical bronze layer serving as an intermediate layer within the base, and a surface coated with modified polyformaldehyde featuring an oil storage pit. Even under boundary lubrication conditions, it can endure prolonged use without requiring additional oiling.

Self-Lubricating – Mining Machinery Bearing

Self-lubricating bronze bushings find extensive applications in mining machinery, marine equipment, aviation, and various other industries. Mining machinery operates under severe production and operational conditions, presenting significant challenges for maintenance. Articulated joints and rotary mechanisms, constrained by limited space for regular lubrication, frequently experience accelerated wear and structural deterioration, compromising the functionality of coal mining equipment.

Self-lubricating bearings present a promising remedy to the issue of inadequate lubrication in coal mines, thanks to their ability to withstand high loads, adaptability to harsh environments, and maintenance-free operation.

Spherical Plain Bearings in Excavator Frame Articulating Ears

The articulated connections between the drill frame and the anchor digger’s components endure frequent vibration and shock loads, often challenging maintenance and lubrication due to space limitations. This difficulty commonly causes joint mechanism failure, resulting in impaired functionality.

Utilizing Cost-Efficient and Durable Spherical Plain Bearings can effectively address these issues. By employing such bearings at the articulated joints of coal mining machinery, not only can the service life of the frame and trunnion be prolonged, but also labor can be minimized while efficiency is enhanced.

Application Of Steel Oilless Bearing At The Redirecting Sprocket

The redirecting sprocket in the transportation section of the anchor digger changes the direction of the scraper chain. The copper sleeve of the sprocket wears severely after 30-60 days, while the wheel body remains unworn. By replacing the copper sleeve with an inlaid graphite bearing with Gcr15 matrix, the sprocket’s lifespan extends from 30-60 days to 210 days without any failures.

Issues with copper sleeve lubrication persist, compounded by difficulties in refilling lubricant. The redirecting sprocket, rotating with the scraper chain, endures cyclic impacts of heavy loads and low speeds. Limited working space, complex environments, and inconvenient operations hinder regular maintenance.

Key Features of Self-Lube Bushings

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.
