Product Description
Product Overview
This flanged graphite embedded bronze bushing is a self-lubricating bearing made of high-strength brass alloy with solid graphite plugs embedded into the bushing surface. The integrated flange design provides axial positioning, simplifies installation and prevents axial movement during operation.
Graphite acts as a solid lubricant. This bush can work without oil refueling, suitable for high load, low speed, intermittent motion and hard-to-reach lubrication environments. It features excellent wear resistance, low friction coefficient, high compressive strength and good shock resistance. Widely used in plastic molds, automation machinery, hydraulic equipment, textile machinery, automotive and construction machinery hinge joints.
Main Features
- Self-lubricating performance: Embedded solid graphite lubricant, no frequent oil supply required. Works well under dry running conditions.
- Flange positioning design: One-piece flange shoulder, easy installation, anti-offset, saves assembly space.
- Premium material: High tensile brass / high strength bronze alloy matrix, strong load capacity and impact resistance.
- Low friction & long service life: Fine machined inner surface, low wear rate, stable performance under heavy load.
- Wide temperature adaptability: Operates within a broad temperature range, suitable for special working conditions.
- Customizable: Support custom inner diameter, outer diameter, length and flange size according to drawings.
