Huge Material Selection
A graphite/bronze alloy, cast bronze metal, graphite and plugged graphite with lubricate; it is a uniform, solid, self-lubricating bushing material.
Mining Machinery Bearing Solution
Mining machinery operates in some of the harshest environments, facing abrasive dust, heavy loads, moisture, and extreme temperatures. Traditional bearings often fail in these conditions, resulting in costly downtime. Self-lubricating bearings are designed for reliability, longevity, and maintenance-free operation.
These oilless bearings are increasingly utilized in mining machinery for their efficiency in harsh conditions without the need for regular lubrication. They can withstand high loads and extreme temperatures, making them suitable for various mining applications.
Bronzeoilless.com offers a selection of self-lubricating bearings for mining equipment, including graphite-embedded bronze bearings and powder metallurgy spherical oilless bushings.
Materials Used in Self-Lubricating Bearings for Mining
The right material ensures durability under stress. Key options include:
- Bronze-Based Bearings
- Oil-Impregnated Sintered Bronze: Embedded lubricant reservoirs provide continuous lubrication, ideal for oscillating movements in conveyor rollers.
- Bronze-PTFE Composites: PTFE layers reduce friction and handle high loads (up to 35 MPa) in crushers.
- Metal-Polymer Composites
- Steel-backed polymers with PTFE or graphite fillers excel in shock absorption and corrosion resistance, perfect for wet environments like slurry pumps.
- PTFE-Lined Bearings
- Low friction and chemical resistance suit high-speed, high-load applications such as excavator pivot points.
Self lubricating bearings VS Traditional Bearings
- Zero Maintenance: Eliminate grease intervals in hard-to-reach areas.
- High Load Capacity: Support up to 70 MPa in crushers.
- Corrosion Resistance: Ideal for acidic/water-exposed environments.
- Temperature Resilience: Operate from -200°C to +300°C (-328°F to 572°F) with specialty materials.
Wear Resistance & Performance in Harsh Conditions
- Abrasion Defense: Embedded solid lubricants (graphite, MoS2) create protective films, reducing wear by 60% vs. oil-lubricated bearings.
- Extreme Temperature Tolerance:
- Bronze-PTFE: Stable up to 250°C (482°F).
- High-performance polymers (PBI): Endure 300°C+ in kiln equipment.
- Contamination Immunity: No risk of lubricant washout in wet or dusty settings.
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 bearings are essential in high-stress areas, including:
- Conveyor Systems:Application: Rollers, pulleys, idlers.
Advantage: Maintenance-free operation in abrasive coal/ore dust.
- Crushers & Grinders: Application: Eccentric shafts, pivot joints.
Advantage: Support impact loads up to 50 tons without lubrication.
- Excavators & Loaders: Application: Bucket pins, boom joints.
Advantage: PTFE linings minimize wear in gritty conditions.
- Drilling Rigs: Application: Rotating drill heads.
Advantage: Endure temperatures up to 250°C (482°F) in deep-earth operations.
Spherical Plain Bearings in Excavator Frame Articulating Ears
The articulated connections between the drill frame and the anchor digger components are exposed to constant vibration and shock loads. These conditions often make maintenance and lubrication challenging due to limited space, leading to joint mechanism failures and reduced functionality.
Using cost-effective and durable spherical plain bearings can help resolve these issues. By installing these bearings at the articulated joints of coal mining machinery, the service life of the frame and trunnion can be extended, reducing labor requirements and improving efficiency.
Self-lubricating bronze bushings are frequently used in mining machinery and marine equipment. Mining machinery, in particular, operates in harsh environments that make maintenance difficult. Articulated joints and rotary mechanisms suffer rapid wear due to limited lubrication, compromising their performance.
Application Of Steel Oilless Bearing At The Redirecting Sprocket
The redirecting sprocket in the anchor digger’s transportation section is responsible for changing the direction of the scraper chain. The copper sleeve on the sprocket experiences significant wear within 30-60 days, while the wheel body remains mostly unaffected. However, by replacing the copper sleeve with an inlaid graphite bearing with a GCr15 matrix, the sprocket’s lifespan is extended from 30-60 days to 210 days without failures.
Lubrication issues with the copper sleeve continue to be a challenge, especially given the difficulties in replenishing the lubricant. The redirecting sprocket, which rotates with the scraper chain, faces cyclic impacts from heavy loads and low speeds. Additionally, limited working space, harsh environments, and difficult operational conditions make regular maintenance challenging. Self-lubricating bearings address these lubrication problems by offering high load capacity, adaptability to tough environments, and maintenance-free operation, making them ideal for coal mining applications.
