Oilless Bronze Bushings in Concrete Block and Brick Making Machines: Applications and Benefits
Graphite Plugged Bronze Bushings are self-lubricating bearings made from a cast bronze matrix embedded with solid graphite plugs, typically covering 20%-40% of the bearing surface. These bushings offer high load capacity, low friction, excellent high-temperature resistance (up to 250°C), and maintenance-free operation. They are ideal for heavy-duty, low-speed, dusty, or hard-to-lubricate industrial environments.
Oilless Bronze Bushings for Tamper Head Sliding, Lifting, and Lowering Mechanisms
In Concrete Block Machines and Brick Making Machines, graphite plugged bronze bushings are widely used in sliding components exposed to high pressure, vibration, and dust. They help reduce wear, extend equipment lifespan, and minimize downtime.
Why They Are Ideal for Concrete Block and Brick Making Machines
1. Suitable for Harsh Operating Conditions
These machines involve high-pressure molding, vibration compaction, and material handling, with loads up to hundreds of tons and low operating speeds (<1 m/s). Dust and moisture levels are high. Traditional oil lubrication can fail, while graphite plugs in oilless bronze bushings release a lubricating film during friction, allowing dry operation without additional lubrication.
2. Performance Advantages
-
Corrosion-resistant for humid conditions
-
Fatigue-resistant and highly wear-resistant
-
Supports intermittent high-load operations
-
Graphite type selectable by temperature: PTFE-based for ≤180°C, graphite-based for >180°C
3. Economic Benefits
-
Maintenance-free design reduces lubrication costs and contamination risk
-
Improves production efficiency, potentially reducing equipment downtime by 20%-30%
Typical Applications in Concrete Block and Brick Machines
Oilless bronze bushings are commonly used in sliding or guiding components that bear axial or radial forces. They are available in cylindrical, flanged, or spherical designs and can be customized based on machine type (vibrating or hydraulic block machines).
| Equipment | Application | Description | Key Benefits |
|---|---|---|---|
| Concrete Block Machine | Vibrating Table / Compacting Mechanism | Supports vibrating beams or press heads, enabling high-frequency vibration compaction of concrete mix. Loads up to 50–100 tons, cyclic operation. | Vibration wear resistance, self-lubrication reduces dust adhesion, improves molding accuracy. |
| Concrete Block Machine | Mold Lifting / Demolding System | Installed on hydraulic cylinder rods or guide columns to support mold movement and block demolding. Handles intermittent high loads and impact. | Low friction ensures smooth movement; impact-resistant, extends mold life (>10,000 cycles). |
| Concrete Block Machine | Conveyor / Pallet Feeder Guides | Fixed on conveyor chains or hopper sliding rails, bearing material weight and horizontal movement. Dusty environment prone to clogging. | Dry operation tolerates dusty conditions, reduces jamming, improves transport efficiency. |
| Brick Making Machine | Extruder Main Shaft / Screw Propeller | Embedded in extruder bearing housing, supports rotational extrusion of bricks. High temperature (>150°C) and torque. | Graphite lubrication resists heat, prevents shaft wear, supports continuous production. |
| Brick Making Machine | Cutting / Brick Separating Mechanism | Bearings for cutting blades or brick separating slides, supporting linear motion. Medium load, low speed. | Low maintenance, corrosion-resistant (suitable for moist clay), reduces cutting errors. |
| Brick Making Machine | Drying / Stacking Arm | Mounted on stacking robot or drying line pivot, enabling brick stacking and movement. Multi-axis rotation. | High fatigue resistance, supports heavy swinging loads, reduces energy consumption. |
Selection and Installation Recommendations
-
Material Selection: Choose alloy based on load and environment (e.g., corrosion-resistant for humid conditions, high-load for compacting mechanisms).
-
Dimensions: Standard sizes follow DIN/ISO norms; custom sizes available.
-
Installation Tips: Pre-coat the bearing surface with a thin lubricant layer for initial run-in; match shaft material (e.g., hardened steel) for optimal performance.
Case Reference: In similar equipment (e.g., Columbia or Masa block machines), these bushings have proven to extend bearing life by 2–3 times, suitable for heavy-duty global applications.
