In high-precision industrial machinery, guide ejector bushings play a crucial role in ensuring smooth, reliable motion of ejector systems. Traditional bushings often rely on external lubrication, which can lead to inconsistent performance, increased wear, and frequent maintenance.
JOSG solid self-lubricating guide ejector bushings combine a high-strength brass alloy base with embedded graphite plugs, providing continuous lubrication, high wear resistance, and long operational life. This article explores the material composition, working principle, advantages, and industrial applications of JOSG bushings using structured data, comparative tables, and technical insights.
Guide ejector bushings are cylindrical components designed to guide linear motion of ejector pins or rods in injection molding, die casting, and pressing machinery.
JOSG bushings distinguish themselves through:
Embedded graphite plugs covering 20–30% of the surface
High-strength brass alloy base (CuZn25Al5Mn4Fe3)
Maintenance-free operation under moderate to high loads
High wear resistance and dimensional stability
The graphite plugs provide a continuous lubricating film, reducing friction and extending the service life of both the bushing and the mating components.
JOSG bushings are made from a high-strength brass alloy (CuZn25Al5Mn4Fe3), which is often equivalent to C86300 or other high-strength bearing brass standards.
Key Material Properties:
| Property | JOSG Bushing (CuZn25Al5Mn4Fe3) | Standard Bronze | Steel |
|---|---|---|---|
| Tensile Strength (MPa) | 450–520 | 350–450 | 500–700 |
| Hardness (HB) | 150–180 | 120–150 | 180–220 |
| Thermal Conductivity (W/m·K) | 70–90 | 50–60 | 45–60 |
| Wear Resistance | High | Medium | Medium |
| Corrosion Resistance | Excellent | Medium | Low |
| Lubricant Integration | Graphite plugs 20–30% | Requires external | Requires external |
Analysis:
The combination of high-strength brass with embedded graphite plugs ensures high load capacity, excellent wear resistance, and low friction, even in high-speed or high-temperature environments.
Brass Alloy Matrix – Provides structural strength, thermal stability, and corrosion resistance.
Graphite Plugs (20–30% Coverage) – Act as a solid lubricant, releasing a thin lubrication layer during operation.
Friction Reduction – The graphite-lubricated surface maintains a low friction coefficient (~0.05–0.12), eliminating the need for external lubrication.
Illustrative Concept:
This design ensures consistent, maintenance-free performance, reducing downtime and operational costs.
Maintenance-Free Operation
Graphite plugs provide continuous lubrication without oil or grease.
High Wear Resistance
Brass alloy matrix resists wear and deformation under repeated cycles.
Corrosion Resistance
Suitable for humid, dusty, or chemically aggressive environments.
Dimensional Stability

Case Study Insight:
An injection molding plant replacing conventional bronze bushings with JOSG solid self-lubricating bushings reported a 35% reduction in maintenance intervals and improved dimensional consistency in molded parts.
| Selection Factor | Key Considerations |
|---|---|
| Load Capacity | Verify the maximum axial or radial load is within the brass alloy tolerance. |
| Motion Type | Linear vs. oscillating motion affects bushing selection. |
| Environment | Choose high corrosion resistance for wet or chemical exposure. |
| Temperature | Ensure graphite plugs and alloy tolerate peak operating temperatures. |
| Surface Coverage | Standard 20–30% graphite coverage is optimal for most applications. |
JOSG solid self-lubricating guide ejector bushings provide maintenance-free, high-precision, and durable performance for industrial machinery. By combining high-strength brass alloys with embedded graphite plugs, these bushings offer:
Continuous lubrication
High wear resistance
Corrosion resistance
Reduced maintenance and operational cost
