What Are Solid Self-Lubricating Straight Bearings?

Solid self-lubricating straight bearings are bushings designed to provide low-friction rotational or sliding motion without external lubrication. Unlike conventional sleeve bearings, the lubrication is pre-embedded in the metal matrix, enabling consistent performance in harsh environments.

Key Features:

Embedded solid lubricants (e.g., graphite or PTFE)

High load-bearing capacity with dimensional stability

Wear and corrosion resistance

Operational efficiency in dry, contaminated, or high-temperature conditions

Why Bronze Alloy C86300?

Bronze alloy C86300 (CuZn25Al5Mn4Fe3) is specifically formulated for high-strength, corrosion-resistant, and self-lubricating applications.

Typical Applications

1. Heavy Machinery & Presses

JDB bronze sleeve bushes handle high loads with minimal friction, ideal for stamping, forging, or extrusion presses.

2. Hydraulic and Pneumatic Cylinders

Embedded lubrication ensures smooth movement in high-pressure cylinders without external grease.

3. Robotics & Automation

Low-friction operation reduces energy consumption and improves precision in repetitive motion systems.

4. Marine and Corrosive Environments

Alloy composition and self-lubricating properties protect against saltwater or chemical exposure.

Industry Insight:

In a medium-sized manufacturing facility using automated conveyor systems, switching to C86300 self-lubricating bushes reduced downtime caused by lubrication failures by over 60%, while extending operational cycles by 25%.
