Flange bushings are critical components in machinery that support axial and radial loads while ensuring smooth rotational or linear motion. Traditional bronze or steel bushings often require external lubrication, which increases maintenance frequency and downtime.
JDBB solid self-lubricating flange bushings, made from nickel aluminum bronze alloy, provide oilless operation, superior load capacity, and corrosion resistance, making them ideal for demanding industrial applications. This article explores their material composition, working principles, advantages, and typical applications, enhanced with tables, charts, and technical insights.
Flange bushings are cylindrical bearings with an integral flange that prevents axial movement and distributes load more evenly.
JDBB bushes stand out for:
High-strength nickel aluminum bronze alloy matrix
Embedded solid lubricants for maintenance-free, oilless operation
Exceptional wear resistance and dimensional stability
High load-bearing capacity and corrosion resistance
The solid lubricants form a self-renewing lubrication layer, reducing friction and wear without external oil or grease.
JDBB flange bushings are made from nickel aluminum bronze (NiAl bronze), an alloy widely used in marine, chemical, and heavy-load applications due to its strength, wear resistance, and corrosion protection.
Key Material Properties:
| Property | JDBB NiAl Bronze | Standard Bronze | Steel |
|---|---|---|---|
| Tensile Strength (MPa) | 450–600 | 350–450 | 500–700 |
| Hardness (HB) | 160–200 | 120–150 | 180–220 |
| Corrosion Resistance | Excellent | Medium | Low |
| Wear Resistance | High | Medium | Medium |
| Thermal Conductivity (W/m·K) | 35–50 | 50–60 | 45–60 |
| Lubricant Integration | Embedded solid plugs | External required | External required |
Analysis:
The nickel aluminum bronze matrix ensures high load capacity and superior corrosion resistance, while solid lubricants provide maintenance-free performance, even in harsh environments.
Nickel Aluminum Bronze Matrix – Provides structural integrity and corrosion resistance, particularly in wet, salty, or chemical environments.
Embedded Solid Lubricants – Form a thin, durable lubrication film during operation.
Load Distribution – The flange ensures even axial load distribution, minimizing stress concentrations.
Friction Reduction – The solid-lubricant layer maintains a low coefficient of friction (~0.05–0.12), reducing wear on both shaft and bushing.
Conceptual Illustration:
This design allows long-lasting, oilless operation with reduced downtime and maintenance.
