Product Description
Product Description
Our flanged graphite plugged bronze bushing is a type of self-lubricating oilless bearing, manufactured from high-strength brass/bronze alloy with solid graphite plugs embedded in the bearing surface. The graphite serves as a solid lubricant, which releases lubrication during operation. It eliminates the need for regular oil refilling, works well under high load, low speed, oscillating and intermittent motion conditions.
The integrated flange design simplifies mounting, provides axial positioning, and saves installation space. This bearing can maintain stable friction performance in high temperature, dust-prone and hard-to-lubricate environments. Widely applied in automation equipment, plastic injection molds, CNC machinery, textile machines, hydraulic cylinders and general mechanical hinge joints.
Product Features
✅ Oilless self-lubricating design, no frequent oil maintenance required
✅ High-strength bronze matrix, excellent wear resistance & compressive strength
✅ Embedded solid graphite lubricant, stable friction coefficient
✅ One-piece flange structure for easy installation and axial limit
✅ Good shock resistance, suitable for heavy load & low-speed working conditions
✅ Customizable sizes, tolerances and graphite layout according to drawings
